Grade paleoliths represent an advance over the eoliths. Eoliths are naturally-broken pieces of stone that are used as tools with little or no further modification. A working edge might be slightly retouched or it might simply show signs of wear. Paleoliths, however, are often deliberately flaked from stone cores and are more extensively modified.
 


THE FINDS OF CARLOS RIBEIRO IN PORTUGAL
The first hint of Carlos Ribeiro's discoveries came to our attention quite accidentally. While going through the writings of the nineteenth-century American geologist J. D. Whitney, we encountered a sentence or two about Ribeiro having discovered flint implements in Miocene formations near Lisbon, Portugal.


We found more brief mentions in the works of S. Laing, a popular English science writer of the late nineteenth century. Curious, we searched libraries, but turned up no works under Ribeiro's name and found ourselves at a dead end. Sometime later, Ribeiro's name turned up again, this time in the 1957 English edition of Fossil Men by Boule and Vallois, who rather curtly dismissed the work of the nineteenth-century Portuguese geologist. We were, however, led by Boule and Vallois to the 1883 edition of Le Prehistorique, by Gabriel de Mortillet, who gave a favorable report of Ribeiro's discoveries, in French. By tracing out the references mentioned in de Mortillet's footnotes, we gradually uncovered a wealth of remarkably convincing original reports in French journals of archeology and anthropology from the latter part of the nineteenth century.


The search for this buried evidence was illuminating, demonstrating how the scientific establishment treats reports of facts that no longer conform to accepted views. Keep in mind that for most current students of paleoanthropology, Ribeiro and his discoveries simply do not exist. You have to go back to textbooks printed over 30 years ago to find even a mention of him.


In 1857, Carlos Ribeiro was named to head the Geological Survey of Portugal, and he would also be elected to the Portuguese Academy of Sciences. During the years 1860-63, he conducted studies of stone implements found in Portugal's Quaternary strata. Nineteenth-century geologists generally divided the geological periods into four main groups:

(1) the Primary, encompassing the periods from the Precambrian through the Permian

(2) the Secondary, encompassing the periods from the Triassic through the Cretaceous

(3) the Tertiary, encompassing the periods from the Paleocene through the Pliocene

(4) the Quaternary, encompassing the Pleistocene and Recent periods

During the course of his investigations, Ribeiro learned that flints bearing signs of human work were being found in Tertiary beds between Canergado and Alemquer, two villages in the basin of the Tagus River northeast of Lisbon.


Ribeiro immediately began his own investigations, and in many localities found flakes of worked flint and quartzite in Tertiary beds. But Ribeiro felt he must submit to the prevailing scientific dogma, still current, that human beings were not older than the Quaternary.


In 1866, on the official geological maps of Portugal, Ribeiro reluctantly assigned Quaternary ages to certain of the implement-bearing strata. Upon seeing the maps, the French geologist Edouard de Verneuil took issue with Ribeiro's judgment, pointing out that the so-called Quaternary beds were certainly Pliocene or Miocene. Meanwhile, in France, the Abbé Louis Bourgeois, a reputable investigator, had reported finding stone implements in Tertiary beds. Influenced by de Verneuil's criticism and the discoveries of Bourgeois, Ribeiro began openly reporting that human implements were being found in Pliocene and Miocene formations in Portugal.


In 1871, Ribeiro presented to the Portuguese Academy of Science at Lisbon a collection of flint and quartzite implements, including some gathered from the Tertiary formations of the Tagus valley. In 1872, at the International Congress of Prehistoric Anthropology and Archeology meeting in Brussels, Ribeiro displayed more specimens, mostly pointed flakes. Scientific opinion was divided.


At the Paris Exposition of 1878, Ribeiro displayed 95 specimens of Tertiary flint tools. Gabriel de Mortillet, the influential French anthropologist, visited Ribeiro's exhibit and declared that 22 specimens had undoubted signs of human work. Along with his friend and colleague Emile Cartailhac, de Mortillet brought other scientists to see Ribeiro's specimens, and they were all of the same opinion—a good many of the flints were definitely made by humans.


De Mortillet wrote:

"The intentional work is very well established, not only by the general shape, which can be deceptive, but much more conclusively by the presence of clearly evident striking platforms and strongly developed bulbs of percussion."

The bulbs of percussion also sometimes had eraillures, small chips removed by the force of impact. Some of Ribeiro's specimens also had several long, vertical flakes removed in parallel, something not likely to occur in the course of random battering by the forces of nature.


Leland W. Patterson, a modern expert on stone tools, holds that the bulb of percussion is the most important sign of intentional work on a flint flake. If the flake also shows the remnants of a striking platform, then one can be even more certain that one is confronted with a flake struck deliberately from a flint core and not a piece of naturally broken flint resembling a tool or weapon.


De Mortillet further observed:

"Many of the specimens, on the same side as the bulb of percussion, have hollows with traces and fragments of sandstone adhering to them, a fact which establishes their original position in the strata." But some scientists were still doubtful. At the 1880 meeting of the International Congress of Prehistoric Anthropology and Archeology, held in Lisbon, Portugal, Ribeiro displayed more specimens from Miocene beds.

 

In his report, Ribeiro stated: "

(1) They were found as integral parts of the beds themselves.

(2) They had sharp, well-preserved edges, showing that they had not been subject to transport for any great distance.

(3) They had a patina similar in color to the rocks in the strata of which they formed a part."

The second point is especially important. Some geologists claimed that Pleistocene flint implements had been washed into fissures in Miocene beds by floods and torrents. But if the flints had been subjected to such transport, then the sharp edges would most probably have been damaged, and this was not the case. The Congress assigned a special commission to inspect the implements and the sites. On September 22, 1880, the commission members boarded a train and proceeded north from Lisbon.

 

During the journey, they gazed at the old forts topping the hilltops, and pointed out to each other the Jurassic, Cretaceous, and Tertiary terrains as they moved through the valley of the Tagus River. They stepped off the train at Carregado. They then proceeded to nearby Otta and two kilometers (just over a mile) from Otta arrived at the hill of Monte Redondo. At that point, the scientists dispersed into various ravines in search of flints.


In his book Le Prehistorique, Gabriel de Mortillet gave an informative account of the events that took place at Monte Redondo:

"The members of the Congress arrived at Otta, in the middle of a great freshwater formation. It was the bottom of an ancient lake, with sand and clay in the center, and sand and rocks on the edges. It is on the shores that intelligent beings would have left their tools, and it is on the shores of the lake that once bathed Monte Redondo that the search was made. It was crowned with success.

 

The able investigator of Umbria [Italy], Mr. Bellucci, discovered in situ a flint bearing incontestable signs of intentional work. Before detaching it, he showed it to a number of his colleagues. The flint was strongly encased in the rock. He had to use a hammer to extract it. It is definitely of the same age as the deposit. Instead of lying flat on a surface onto which it could have been secondarily recemented at a much later date, it was found firmly in place on the underside of a ledge extending over a region removed by erosion. It is impossible to desire a more complete demonstration attesting to a flint's position in its strata."

Some modern authorities consider the Otta conglomerates to be Early Miocene, about 15-20 million years old. Altogether, there seems little reason why Ribeiro's discoveries should not be receiving some serious attention, even today.
 


THE FINDS OF L. BOURGEOIS AT THENAY, FRANCE
On August 19, 1867, in Paris, L. Bourgeois presented to the International Congress for Prehistoric Anthropology and Archeology a report on flint implements he had found in Early Miocene beds (15-20 million years old) at Thenay, in north-central France. Bourgeois said they resembled the types of Quaternary implements (scrapers, borers, blades, etc.) he had found on the surface in the same region. He found on almost all of the Miocene specimens the standard indications of human work: fine retouching, symmetrical chipping, and traces of use.


At the Paris congress, only a few scientists admitted they were actual artifacts. Undeterred, Bourgeois continued finding more specimens and convincing individual paleontologists and geologists they were the result of intentional work. Gabriel de Mortillet was one of the first to be so convinced.


Some scientists questioned the stratigraphic position in which the flints had been found. The first specimens collected by Bourgeois came from rocky debris along the sides of a small valley cutting through the plateau at Thenay. Geologists such as Sir John Prestwich objected that these were essentially surface finds. In response, Bourgeois dug a trench in the valley and found flints showing the same signs of human work.


Still unsatisfied, critics proposed that the flints found in the trench had come to their positions through fissures leading from the top of the plateau, where Pleistocene implements were often found. To meet this objection, Bourgeois, in 1869, sank a pit into the top of the plateau. During the excavation, he came to a layer of limestone one foot thick, with no fissures through which Pleistocene stone tools might have slipped to lower levels.


Deeper in his pit, at a depth of about 14 feet in Early Miocene strata, Bourgeois discovered many flint tools. De Mortillet stated in Le Prehistorique:

"There was no further doubt about their antiquity or their geological position."

Despite this clear demonstration, many scientists retained their unreasonable doubts. A showdown came in Brussels, at the 1872 meeting of the International Congress of Prehistoric Anthropology and Archeology.


Bourgeois presented many specimens, figures of which were included in the published proceedings of the Congress. Describing a pointed implement, Bourgeois stated:

"Here is an awl-like specimen, on a broad base. The point in the middle has been obtained by regular retouching. This is a type common to all epochs. On the opposite side is a bulb of percussion."

Bourgeois described another implement, which he characterized as a knife or cutting tool:

"The edges have regular retouching, and the opposite side presents a bulb of percussion."

On many of his specimens, noted Bourgeois, the edges on the part of the tool that might be grasped by the hand remained unworn, while those on the cutting surfaces showed extensive wear and polishing.


Another specimen, was characterized by Bourgeois as a projectile point or an awl. He noted the presence of retouching on the edges, obviously intended to make a sharp point. Bourgeois also saw among the objects he collected a core with the two extremities retouched with the aim of being utilized for some purpose. He observed:

"The most prominent edge has been chipped down by a series of artificial blows, probably to prevent discomfort to the hand grasping the implement. The other edges remain sharp, which shows this flaking is not due to rolling action."

In order to resolve any controversy, the Congress of Prehistoric Anthropology and Archeology nominated a fifteen-member commission to judge the discoveries of Bourgeois. A majority of eight members voted that the flints were of human manufacture. Only five of the fifteen found no trace of human work in the specimens from Thenay. One member expressed no opinion and another supported Bourgeois with some reservations.


Bulbs of percussion were rare on the Early Miocene flints of Thenay, but most of the flints displayed fine retouching of the edges. The retouching tended to be concentrated on just one side of an edge, while the other side remained untouched; this is called unifacial flaking. De Mortillet, like modern authorities, believed that in almost all cases unifacial flaking is not the result of chance impacts but of deliberate work. In his book Musée Prehistorique, de Mortillet included reproductions of some Thenay flints that displayed very regular unifacial retouching.


Some of the critics of Bourgeois commented that among all the Early Miocene flint pieces he collected at Thenay, there were only a very few good specimens, about thirty. But de Mortillet stated:

"Even one incontestable specimen would be enough, and they have thirty!"

Modern authorities on stone stools, such as L. W. Patterson, say that parallel flake scars of approximately the same size are good indications of human work. Illustrations of the flints from the Early Miocene of Thenay show such flake scars.
Many of the flints of Thenay have finely cracked surfaces indicating exposure to fire. De Mortillet concluded that humans had used fire to fracture large pieces of flint. The resulting flakes were then made into tools.


Through the writings of S. Laing, knowledge of the Thenay tools from the Early Miocene reached the intelligent reading public of the English-speaking countries.

 

Laing stated:

"The human origin of these implements has been greatly confirmed by the discovery that the Mincopics of the Andaman Islands manufacture whet-stones or scrapers almost identical with those of Thenay, and by the same process of using fire to split the stones into the requisite size and shape. On the whole, the evidence for these Miocene implements seems to be very conclusive, and the objections to have hardly any other ground than the reluctance to admit the great antiquity of man."

Who made the flint implements of Thenay? Some thought they had been made by primitive, apelike human ancestors.

 

But in 1894, S. Laing said of the flints of Thenay:

"Their type continues, with no change except that of slight successive improvements, through the Pliocene, Quaternary, and even down to the present day. The scraper of the Esquimaux and the Andaman islanders is but an enlarged and improved edition of the Miocene scraper."

If humans make such scrapers today, it is certainly possible that identical beings made similar scrapers back in the Miocene. And, as we shall see in coming chapters, scientists did in fact uncover skeletal remains of human beings indistinguishable from Homo sapiens in the Tertiary.


It thus becomes clearer why we no longer hear of the flints of Thenay. At one point in the history of paleoanthropology, several scientists who believed in evolution actually accepted the Thenay Miocene tools, but attributed them to a precursor of the human type. Evolutionary theory convinced them such a precursor existed, but no fossils had been found. When the expected fossils were found in 1891, in Java, they occurred in a formation now regarded as Middle Pleistocene. That certainly placed any supporters of Miocene ape-men in a dilemma.

 

The human precursor, the creature transitional between fossil apes and modern humans, had been found not in the Early Miocene, 20 million years ago by current estimate, but in the Middle Pleistocene, less than 1 million years ago. Therefore, the flints of Thenay, and all the other evidences for the existence of Tertiary humans (or tool-making Tertiary ape-men), were quietly, and apparently quite thoroughly, removed from active consideration and then forgotten.


The extensive evidence for the presence of tool-making hominids in the Tertiary was in fact buried, and the stability of the entire edifice of modern paleoanthropology depends upon it remaining buried. If even one single piece of evidence for the existence of toolmakers in the Miocene or Early Pliocene were to be accepted, the whole picture of human evolution, built up so carefully in this century, would disintegrate.
 


IMPLEMENTS FROM AURILLAC, FRANCE
In 1870, Anatole Roujou reported that geologist Charles Tardy had removed a flint knife from the exposed surface of a Late Miocene conglomerate at Aurillac, in southern France. To describe the removal, Roujou used the word arraché, which means the flint had to be extracted with some force. De Mortillet believed Tardy's flint tool had only recently been cemented onto the surface of the Late Miocene conglomerate and therefore chose to assign it a Pleistocene date.


The French geologist J. B. Rames doubted that the object found by Tardy was actually of human manufacture. But in 1877 Rames made his own discoveries of flint implements in the same region, at Puy Courny, a site near Aurillac. These implements were taken from sediments lying between layers of volcanic materials laid down in the Late Miocene, about 7-9 million years ago.


In 1894, S. Laing gave a detailed description of the signs of human manufacture that Rames had observed on the flints:

"The specimens consist of several well-known palaeolithic types, celts, scrapers, arrow-heads, and flakes, only ruder and smaller than those of later periods. They were found at three different localities in the same stratum of gravel, and comply with all the tests by which the genuineness of Quaternary implements is ascertained, such as bulbs of percussion, conchoidal fractures, and above all, intentional chipping in a determinate direction."

According to Laing, French anthropologist Armand de Quatrefages noted fine parallel scratches on the chipped edges of many specimens, indicating usage. These use marks were not present on other unchipped edges. The flint implements of Puy Courny were accepted as genuine at a congress of scientists in Grenoble, France.


Laing also said about the tools:

"The gravelly deposit in which they are found contains five different varieties of flints, and of these all that look like human implements are confined to one particular variety, which from its nature is peculiarly adapted for human use. As Quatrefages says, no torrents or other natural causes could have exercised such a discrimination, which could only have been made by an intelligent being, selecting the stones best adapted for his tools and weapons."

Max Verworn, of the University of Gottingen in Germany, was initially doubtful of reports of stone tools from the Pliocene and earlier. So in 1905 he went to Aurillac to conduct his own investigations of the stone tools found there.


Verworn remained at Aurillac for six days, making excavations at a site called Puy de Boudieu, not far from Puy Courny.

 

Describing the results of his first day's work, he wrote:

"I had the luck to come upon a place where I found a great number of flint objects, whose indisputable implemental nature immediately staggered me. I had not expected this. Only slowly could I accustom myself to the thought that I had in my hand the tools of a human being that had lived in Tertiary times. I raised all the objections of which I could think. I questioned the geological age of the site, I questioned the implemental nature of the specimens, until I reluctantly admitted that all possible objections were not sufficient to explain away the facts."

The sharp-edged, chipped flint objects, apparently tools, were found in small groups, among stones that were very much rolled and worn. This meant that the flint objects had not been subjected to much movement since their deposition and that the flaking upon them was therefore of human rather than geological origin. The fact that the sharp-edged implemental flints were found in groups also suggested the presence of workshop sites.


Verworn then discussed at length various ways to identify human work on a flint object. He divided evidence of such work into three groups:

(1) signs of percussion resulting from the primary blow that detached the flake from a flint core

(2) signs of percussion resulting from secondary edge chipping on the flake itself

(3) signs of use on the working edges

Considering all the various characteristics of percussion and use, Verworn suggested that none of them are in themselves conclusive.

"The critical analysis of a given combination of symptoms is the only thing that will put us in a position to make decisions," he stated.

This is the same methodology suggested by L. W. Patterson, a modern expert on stone tools. Patterson does, however, give more weight than Verworn to bulbs of percussion and unidirectional flaking along single edges of flakes, especially when numerous specimens are found at a site. Patterson's studies showed that natural forces almost never produce these effects in significant quantities.


Verworn then provided an example to illustrate how his method of analysis might be applied:

"Suppose I find in an interglacial stone bed a flint object that bears a clear bulb of percussion, but no other symptom of intentional work. In that case, I would be doubtful as to whether or not I had before me an object of human manufacture. But suppose I find there a flint which on one side shows all the typical signs of percussion, and which on the other side shows the negative impressions of two, three, four, or more flakes removed by blows in the same direction. Furthermore, let us suppose one edge of the piece shows numerous, successive parallel small flakes removed, all running in the same direction, and all, without exception, are located on the same side of the edge. Let us suppose that all the other edges are sharp, without a trace of impact or rolling. Then I can say with complete certainty it is an implement of human manufacture."

Verworn, after conducting a number of excavations at sites near Aurillac, analyzed the many flint implements he found, employing the rigorously scientific methodology described above. He then came to the following conclusion:

"With my own hands, I have personally extracted from the undisturbed strata at Puy de Boudieu many such unquestionable artifacts. That is unshakable proof for the existence of a flint-working being at the end of the Miocene."

Most of the implements found by Verworn in the Miocene beds of Aurillac were scrapers of various kinds. "Some scrapers," he wrote,

"show only use marks on the scraping edge, while the other edges on the same piece are quite sharp and unmarked. On other specimens the scraping edge displays a number of chips intentionally removed in the same direction. This chipping displays quite clearly all the usual signs of percussion. Even today the edges of the impact marks of previous blows on the upper part of some implements are perfectly sharp. The goal of the work on the edges is clearly and without doubt recognizable as the removal of cortex or the giving of a definite form. On many pieces there are clearly visible handgrip areas, fashioned by the removal of sharp edges and points from places where they would injure or interfere."

About another object, Verworn said:

"The flake scars on the scraper blade lie so regularly next to each other in parallel fashion that one is reminded of Paleolithic or even Neolithic examples."

In the accepted sequence, Paleolithic and Neolithic tools are assigned to the later Pleistocene.


Verworn also found many pointed scrapers:

"Among all the flint objects, these show most clearly the intentional fashioning of definite tool shapes, at least in the area of the working edges. In fact, the points are generally made in such a way that one can speak of genuine care and attention in the technique. The edges have been worked by many unidirectional blows in such a way as to make the intention of fashioning a point unequivocal."

Also found at Aurillac were notched scrapers, with rounded concave openings on the working edge suitable for scraping cylindrical objects like bones or spear shafts. Verworn observed:

"In most cases the notched scrapers are made by chipping out one of the edges in a curved shape by unidirectional blows."

Verworn also uncovered several tools adapted for hammering, hacking, and digging. Describing one such tool, Verworn wrote:

"A large pointed tool for chopping or digging. It is formed from a natural slab of flint by the working of a point. One sees on the surfaces of the piece the cortex of the flint and at the top a point made from numerous flakes, mostly removed in the same direction."

About another pointed tool, Verworn stated:

"This tool has on the side directly below the point a handgrip made by removing the sharp, cutting edges. It might have been a primitive hand axe used for hammering or chopping."

Verworn also found tools he thought were adapted for stabbing, boring, and engraving.


Verworn concluded:

"At the end of the Miocene there was here a culture, which was, as we can see from its flint tools, not in the very beginning phases but had already proceeded through a long period of development. . . . this Miocene population of Cantal knew how to flake and work flint."

Verworn went on to say:

"The size of the implements points toward a being with a hand of the same size and shape as our own, and therefore a similar body. The existence of large scrapers and choppers that fill our own hands, and above all the perfect adaptation to the kind found in almost all the tools, seems to verify this conclusion in the highest degree.


Tools of the most different sizes, which show with a perfect clarity useful edges, use marks, and hand-grips, lie for the most part so naturally and comfortably in our hands, with the original sharp points and edges intentionally removed from the places where a hand would grasp, that one would think the tools were made directly for our hands."

Verworn then said about the makers of the tools:

"While it is possible that this Tertiary form might possibly have stood closer to the animal ancestors of modern humans than do modern humans themselves, who can say to us that they were not already of the same basic physical character as modern humans, that the development of specifically human features did not extend back into the Late Miocene?"

As we explain in Chapter 7, fossil skeletal remains indistinguishable from those of fully modern humans have been found in the Pliocene, Miocene, Eocene and even earlier. When we also consider that humans living today make implements not much different from those taken from Miocene beds in France and elsewhere, then the validity of the standard sequence of human evolution begins to seem tenuous.

 

In fact, the standard sequence only makes sense when a lot of very good evidence is ignored. When all the available evidence, implemental and skeletal, is considered, it is quite difficult to construct any kind of evolutionary sequence. What we are left with is the supposition that there have been various types of human and humanlike beings, living at the same time and manufacturing stone tools of various levels of sophistication, for tens of millions of years into the past.


As late as 1924, George Grant MacCurdy, director of the American School of Prehistoric Research in Europe, reported positively in Natural History about the flint implements of Aurillac. Similar tools had been found in England by J. Reid Moir. Some critics argued that natural forces, such as movements of the earth, had fractured flints by pressure, thus creating stone objects resembling tools. But scientists showed that in the particular locations where Moir's flint tools were found, the geological evidence did not suggest the operation of such natural causes.


MacCurdy wrote:

"Conditions favoring the play of natural forces do not exist in certain Pliocene deposits of East Anglia, where J. Reid Moir has found worked flints. . . . Can the same be said of the chipped flints from Upper Miocene deposits near Aurillac (Cantal)? Sollas and Capitan have both recently answered in the affirmative. Capitan finds not only flint chips that suggest utilization but true types of instruments which would be considered as characteristic of certain Palaeolithic horizons. These not only occur but reoccur: punches, bulbed flakes, carefully retouched to form points and scrapers of the Mousterian type, disks with borders retouched in a regular manner, scratchers of various forms, and, finally, picks. He concludes that there is a complete similitude between many of the chipped flints from Cantal and the classic specimens from the best-known Palaeolithic sites."

William Sollas held the Chair of Geology at Oxford, and Louis Capitan, a highly respected French anthropologist, was professor at the College of France.
 


DISCOVERIES BY A. RUTOT IN BELGIUM
In Belgium, A. Rutot, conservator of the Royal Museum of Natural History in Brussels, made a series of discoveries that brought anomalous stone-tool industries into new prominence during the early twentieth century. Most of the industries identified by Rutot dated to the Early Pleistocene. But in 1907, Rutot's ongoing research resulted in more startling finds in sandpits near Boncelles, in the Ardennes region of Belgium. The tool-bearing layers were Oligocene, which means they were from 25 to 38 million years old.


Describing the tools, George Schweinfurth wrote in the Zeitschrift für Ethnologie:

"Among them were choppers, anvil stones, knives, scrapers, borers, and throwing stones, all displaying clear signs of intentional work that produced forms exquisitely adapted for use by the human hand. . . . the fortunate discoverer had the pleasure to show the sites to 34 Belgian geologists and students of prehistory. They all agreed that there could be no doubt about the position of the finds."

Rutot's complete report on the Boncelles finds appeared in the bulletin of the Belgian Society for Geology, Paleontology, and Hydrology. Rutot also said that stone tools like those of Boncelles had been found in Oligocene contexts at Baraque Michel and the cavern at Bay Bonnet. At Rosart, on the left bank of the Meuse, stone tools had also been found in a Middle Pliocene context.

"Now it appears," wrote Rutot, "that the notion of the existence of humanity in the Oligocene . . . has been affirmed with such force and precision that one cannot detect the slightest fault."

Rutot noted that the Oligocene tools from Boncelles almost exactly resembled tools made within the past few centuries by the native inhabitants of Tasmania.


Rutot then described in detail the various types of tools from the Oligocene of Boncelles, beginning with percuteurs (or choppers). These included: plain choppers, sharpened choppers, pointed choppers, and retouchers, which were used to resharpen the working edges of other stone implements. All categories of percuteurs displayed chipping to make the implements easier to hold in the hand and signs of usage on the working edge.


Also found at the Boncelles sites were several anvil stones characterized by a large flat surface showing definite signs of percussion.


Rutot then described some implements he called couteaux, best translated as cutters.

"One can see," he wrote, "that couteaux are made from relatively long flakes of flint, blunt on one side and sharp on the other."

Another type of implement was the racloir, or side scraper. The racloir was ordinarily made from an oval flake, with one of the edges blunt and the opposite edge sharp. After retouching for a suitable grip, the blunt edge was held in the palm of the hand, and the sharp edge of the implement was moved along the length of the object to be scraped. During this operation, small splinters were detached from the cutting edge of the implement and these use marks could be seen on many specimens.


Rutot then described other types of racloirs: the notched racloir, probably used for scraping long, round objects, and the double racloir with two sharp edges. Some of the double racloirs resembled Mousterian pointed implements from the Late Pleistocene.


Rutot also described a special category of tools, which he called mixed implements, because they looked as if they could have been employed in more than one fashion.

 

Rutot stated:

"They tend to have on the sharp edge a point formed by the intersection of two straight edges, or more frequently, two notches, made by retouching."

The next type of implement discussed by Rutot was the grattoir, another category of scraper. He also described percoirs, which might be called awls or borers. Rutot also noted the presence at Boncelles of objects that appeared to be throwing stones or sling stones. Finally, Rutot suggested that certain flint objects bearing traces of repeated impacts may have been used by the ancient inhabitants of Boncelles to make fire. Such stones are found in Late Pleistocene tool collections.

"We find ourselves," Rutot said, "confronted with a grave problem—the existence in the Oligocene of beings intelligent enough to manufacture and use definite and variegated types of implements."

Today scientists do not give any consideration at all to the possibility of a human—or even protohuman—presence in the Oligocene. We believe there are two reasons for this—unfamiliarity with evidence such as Rutot's and unquestioning faith in currently held views on human origin and antiquity.
 


DISCOVERIES BY FREUDENBERG NEAR ANTWERP
In February and March of 1918, Wilhelm Freudenberg, a geologist attached to the German army, was conducting test borings for military purposes in Tertiary formations west of Antwerp, Belgium. In clay pits at Hoi, near St. Gillis, and at other locations, Freudenberg discovered flint objects he believed to be implements, along with cut bones and shells. Most of the objects came from sedimentary deposits of the Scaldisian marine stage.

 

The Scaldisian spans the Early Pliocene and Late Miocene and is thus 4-7 million years old. Freudenberg suggested that the objects he discovered may have dated to the period just before the Scaldisian marine transgression, which, if true, would give them an age of at least 7 million years.


Freudenberg believed some of the flint implements he found had been used to open shells. Many of these were found along with cut shells and burned flints, which Freudenberg took as evidence that intelligent beings had used fire during the Tertiary in Belgium.

 

Concerning the cut shells, Freudenberg stated:

"I found many intentional incisions, mostly on the rear part of the shells, quite near the hinge."

He said the incisions were "such as could only have been made with a sharp instrument." Some of the shells also bore puncture marks. In addition to cut shells, Freudenberg also found bones of marine mammals bearing what he thought were cut marks. He carefully considered and rejected alternative hypotheses such as chemical corrosion or geological abrasion. He also found bones bearing deep impact marks that could have been made by stone hammers.

 

Further confirmation of a human presence came in the form of partial footprints, apparently made when humanlike feet compressed pieces of clay. From a clay pit at Hoi, Freudenberg recovered one impression of the ball of a foot and four impressions of toes. According to Freudenberg, patterns of ridges and pores matched those of human feet and were distinct from those of apes.


Freudenberg was an evolutionist and believed that his Tertiary man must have been a small hominid, displaying, in addition to its humanlike feet, a combination of apelike and human features. Altogether, Freudenberg's description of his Flemish Tertiary man seems reminiscent of Australopithecus. But one would not, according to current paleoanthropological doctrine, expect to find any australopithecines in Belgium during the Late Miocene, over 7 million years ago. The oldest australopithecines date back only about 4 million years in Africa.


Then who made the footprints discovered by Freudenberg? There are today, in Africa and the Philippines, pygmy tribes, with adult males standing less than five feet tall and females even shorter. The proposal that a small human being rather than an australopithecine made the footprints is more consistent with the whole spectrum of evidence—stone tools, incised bones, isolated signs of fire, and artificially opened shells. Australopithecines are not known to have manufactured stone tools or used fire.
 


CENTRAL ITALY
In 1871, Professor G. Ponzi presented to the meeting in Bologna of the International Congress of Prehistoric Anthropology and Archeology a report about evidence for Tertiary humans in central Italy. The evidence consisted of pointed flint implements recovered by geologists from deposits of breccia from the Pliocene Acquatraversan erosional phase (over 2 million years old). A breccia is a deposit composed of rock fragments in a fine-grained matrix of hardened sand or clay.
 


STONE TOOLS FROM BURMA
In 1894 and 1895, scientific journals announced the discovery of worked flints in Miocene formations in Burma, then part of the British India. The implements were reported by Fritz Noetling, a paleontologist who directed the Geological Survey of India in the region of Yenangyaung, Burma.


While collecting fossils, Noetling noticed a rectangular flint object. He said its implement like form was "difficult to explain by natural causes."

 

Noetling noted,

"The shape of this specimen reminds me very much of the chipped flint described in Volume I of the Records, Geological Survey of India, and discovered in the Pleistocene of the Nerbudda river, the artificial origin of which nobody seems to have ever doubted."

Noetling searched further and found about a dozen more chipped pieces of flint.


How certain was the stratigraphic position of Noetling's flints?

 

Noetling offered this account:

"The exact spot where the flints were found . . . is situated on the steep eastern slope of a ravine, high above its bottom, but below the edge in such a position that it is inconceivable how the flints should have been brought there by any foreign agency. There is no room for any dwelling place in this narrow gorge, nor was there ever any; it is further impossible from the way in which the flints were found that they could have been brought to that place by a flood. If I weigh all the evidence, quite apart from the fact that I actually dug them out of the bed, it is my strong belief that they were in situ when found."

In conclusion, Noetling said:

"If flints of this shape can be produced by natural causes, a good many chipped flints hitherto considered as undoubtedly artificial [i.e., human] products are open to grave doubts as to their origin."
 

TOOLS FROM BLACK'S FORK RIVER, WYOMING
In 1932, Edison Lohr and Harold Dunning, two amateur archeologists, found many stone tools on the high terraces of the Black's Fork River in Wyoming, U.S.A. The implements appeared to be of Middle Pleistocene age, which would be anomalous for North America.


Lohr and Dunning showed the tools they collected to E. B. Renaud, a professor of anthropology at the University of Denver. Renaud, who was also director of the Archaeological Survey of the High Western Plains, then organized an expedition to the region where the tools were found. During the summer of 1933, Renaud's party collected specimens from the ancient river terraces between the towns of Granger and Lyman.


Among the specimens were crude hand axes and other flaked implements of a kind frequently attributed to Homo erectus, who is said to have inhabited Europe during the Middle Pleistocene.


The reaction from anthropologists in America was negative. Renaud wrote in 1938 that his report had been "harshly criticized by one of the irreconcilable opponents of the antiquity of man in America, who had seen neither the sites nor the specimens."


In response, Renaud mounted three more expeditions, collecting more tools. Although many experts from outside America agreed with him that the tools represented a genuine industry, American scientists have continued their opposition to the present day.


The most common reaction is to say the crude specimens are blanks (unworked flakes) dropped fairly recently by Indian toolmakers. But Herbert L. Minshall, a collector of stone tools, stated in 1989 that the tools show heavy stream abrasion even though they are fixed in desert pavements on ancient flood plain surfaces that could not have had streams for over 150,000 years.


If found at a site of similar age in Africa or Europe or China, stone tools like those found by Renaud would not be a source of controversy. But their presence in Wyoming is certainly very much unexpected at 150,000 or more years ago. The view now dominant is that humans entered North America not earlier than about 30,000 years ago at most. And before that there was no migration of any other hominid.


Some suggested that the abrasion on the implements was the result of windblown sand rather than water.

 

In reply Minshall observed:

"The specimens were abraded on all sides, top and bottom, ventral and dorsal surfaces equally. That is extremely unlikely for windblown dust to achieve on heavy stone tools lying in heavy gravel but expectable on objects subjected to surf or heavy stream action."

Minshall also noted that the tools were covered with a thick mineral coating of desert varnish. This varnish, which takes a long time to accumulate, was thicker than that on tools found on lower, and hence more recent, terraces in the same region.
The cumulative evidence appears to rule out the suggestion that the implements discovered by Renaud were blanks dropped fairly recently on the high desert floodplain terraces.

 

But Minshall noted:

"The reaction of American scientists to Renaud's interpretation of the Black's Fork collections as evidences of great antiquity was, and has continued to be for over half a century, one of general skepticism and disbelief, even though probably not one in a thousand archaeologists has visited the site nor seen the artifacts."

According to Minshall, the tools found by Renaud were the work of Homo erectus, who may have entered North America during a time of lowered sea levels in the Middle Pleistocene. Minshall believed this was also true of stone tools found at other locations of similar age, such as Calico and his own excavation at Buchanan Canyon, both in southern California.
Minshall was, however, skeptical of another Middle Pleistocene site. In January 1990, Minshall told one of us (Thompson) that he was not inclined to accept as genuine the technologically advanced stone tools found at Hueyatlaco in Mexico (Chapter 5).

 

The advanced stone tools found at Hueyatlaco were characteristic of Homo sapiens sapiens and were thus not easy to attribute to Homo erectus. Minshall's response to Hueyatlaco was to suggest, without supporting evidence, that the stratigraphy had been misinterpreted and that the animal bones used to date the site, as well as the sophisticated stone artifacts, had been washed onto the site from different sources.

 

This shows that researchers who accept some anomalies may rule out others using the double standard method.
