Issue Sourcebook Project Sourcebook Subjects The 50,000-year-old americans of pedra furada French archeologists (not American) have established to the satisfaction of most European archeologists (not American) that humans were present in Brazil at least 50,000 years ago. F. Parenti, with N. Guidon, presented their data at a recent Paris meeting. The main site studied was the sandstone rock shelter of Pedra Furada, which is one of several hundred painted rock shelters discovered in northeastern Brazil. Guidon began her work in 1978; Parenti, in 1984. The fourvolume, 7-kilogram report (actually Parenti's doctoral thesis) concentrates on three lines of evidence: A coherent series of 54 radiocarbon dates ranging from 5,000 to 50,000 years. Crudely flaked stones ... some 6,000 of which are deemed of human manufacture, even when the most stringent criteria are applied. Many of these came from Pleistocene strata 50,000 years old or older. Some 50 Pleistocene "structures" consisting of artificial arrangements of stones, some burned, some accompanied by charcoal. These are likely ancient hearths. (Bahn, Paul G.; "50,000-Year-Old Americans of Pedra Furada," Nature, 362:114, 1993.) Comment.

"At a conference here this week at the University of Maine, Niede Guidon, an archeologist at the Institute of Advanced Social Science Studies in Paris, startled scientists by reporting new results that she said showed the Brazilian rock shelters were occupied by humans at least as long ago as 45,000 years. The 'quantity, diversity and preservation' of materials at the sites, she said, shoud lead to 'profound changes in the knowledge of prehistoric America.'" The Brazilian rock shelters, particularly Pedra Furada, boast elaborate paintings, fireplaces, tools, and butchered-animal bones. (See SF ... 54 from 1987.) Although some American archeologists have edged back to 13,000 BP, others are still stonewalling at 12,000 BP or less. Actually, the debate has become unscientific on occasion, as revealed by R.

"The view that man did not arrive on the American continent before the last glaciation has been supported by the fact that until now the known and dated archaeological sites have not been of very great antiquity. But now we report radiocarbon dates from a Brazilian site which establish that early man was living in South America at least 32,000 years ago. These new findings come from the large painted rock shelter of Boqueirao do Sitio da Pedra Furada, the walls and ceiling of which are decorated with a rich set of prehistoric paintings.

In this sense, balanced rocks are measures of seismic stability. For example, says J. Brune, you won't find PBRs within 10 miles of spots where quakes have shaken the ground over the past few thousand years. To illustrate: "Rocks stacked in piles and balanced on their narrow ends on Yucca Mountain near the Nevada border with California, he said, have not moved in at least 10,000 years and perhaps as many as 100,000 years, judging from the depth of "rock varnish," or weathering, on their exposed surfaces." Looking for PBRs is not really as useless as it sounds, for they are indicators of stability to construction engineers planning nuclear waste disposal sites and similar projects requiring long-term seismic quiet.

And he has brought back some 4,000 stone tools collected at 15 sites in the Siberian permafrost to bolster his claim that Siberia, too, was a point of origin for hominids (see map). "Molchanov's controversial evidence is indeed striking: a collection of chipped and flaked rocks that are clearly artifacts fashioned by humanlike hands and that he contends are 2.5 million years old -- plus or minus a half-million years. "Remarkably, that same era marked the time when early human ancestors known as Homo habilis lived and left their remains in the tropical Olduvai Gorge of what is now Tanzania. Mochanov's collection of tools closely resembles the ones that ... in Africa." All this contrasts strongly with the dominant view of hominid evolution, which cites warm, verdant African forests and savannas as our most likely place of origin. Siberia, with its -50 winters and fleeting summers, hardly seems conducive to hominid speciation. Mochanov's rationale is that this severe climate actually stimulated ancient hominids to create tools, fashion warm clothing, and build winter shelters -- these Siberian hominids had to evolve or perish! In addition to the climate factor are two other problems: (1 ) The Siberian sites have yielded no hominid bones nor have animal bones of any kind been found; and (2 ) The dating of the tools is shaky.

Ob-viously the Principle of Superposition is contradicted in such situations. Two possible explanations exist for these inverted strata: (1 ) The dating of the rocks is incorrect; or (2 ) Geological forces somehow slid the older rocks over the top of the younger rocks. Few mainstream scientists give any thought to the first possibility because it implies that evolution did not proceed as presently envisioned. (Rocks are often dated by their fossil contents.) So, geologists are left with the problems of sliding great masses of rock over rough surfaces for great distances. Sketch of the forces acting upon a thrust block being pushed by a wedge-shaped driver Low-angle thrust faulting is not a trivial geological process. To illustrate, the Lewis Overthrust in Montana and adjacent Canada involves the shoving of a block of old strata hundreds of feet thick, hundreds of miles long, over younger rock for a distance of possibly 50 miles. In contemplating such overthrusts, one immediately comes face to face with the Mechanical Paradox. Brief-ly, given the coefficient of friction between the layers of rock, the weight of the thrust block, and the mechanical strength of the rock being pushed, it can be shown that pushing the thrust block at the rear edge will crush it long before it begins to slide.

Recent divers have found boul-der alignments; but the visibility is so poor that organized structures cannot be identified. Truncated earthen pyramids exist at nearby precolumbian Aztalan; and strange rock piles exist elsewhere in Wisconsin.

"Sharply angular boulders as large as 320 kg [700 pounds] sit on the Racetrack Playa, Death Valley, California; trails leading to them indicate that the rocks have moved large distances. The process has never been witnessed. Although high winds and a wetted surface seem necessary, controversy persists about the need for other conditions, especially ice sheets.

Waller has visited rock art sites in Europe, North America, and Australia. Standing well back from the painted walls, he claps or creates percussion sounds, and records the echos bouncing back. A casual observer might be tempted to call 911. It turns out, though, that rock art seems to be placed intentionally where echos are not only unusually loud but are also related to the pictured subject matter. Where hooved animals are depicted, one easily evokes echos of a running herd. If a person is drawn, the echos of voices seem to emanate from the picture itself! "At open air sites with paintings, Waller found that echos reverberate on average at a level 8 decibels above the level of the background. At sites without art the average was 3 decibels. In deep caves such as Lascaux and Font-de-Gaume in France, echos in painted chambers produce sound levels of between 23 and 31 decibels. Deep cave walls painted with cats produce sounds from about 1 to 7 decibels. In contrast, surfaces without paint are 'totally flat'." What did the ancient artists have against cats?

Any oil that was created billions of years ago would have surely been destroyed by intense pressures and high temperatures over the eons. Yet, Precambrian oil in commercial quantities has been found in formations up to 2 billion years old (in Siberia, Australia, Michigan, for example). While some of this oil might have migrated in-to the Precambrian rocks from younger source rocks, some of it does seem indigenous and, therefore, ancient. (SF#48) Now, three Australian scientists (R . Buick, B. Rasmussen, B. Krapez) have discovered tiny nodules of bitumen (lumps of hydrocarbons) in sedimentary rocks up to 3.5 billion years old in Africa and Australia. These bitumen nodules were formed when natural hydrocarbons were irradiated by radioactive isotopes that coexisted in the ancient rocks. Futhermore, these African and Australian rock formations were never severely deformed or subjected to high temperatures. The possibility exists, therefore, that some of the earth's oldest rocks may contain substantial oil reserves. So far, no one has seriously looked for oil in Precambrian rocks because of the two preconceptions ...

A few years ago the answer to this question would have been a resounding "no" from the experts on both volcanism and impact cratering, the only geological processes known to eject solid material at substantial velocities. Observation, however, has once again confounded expectation." In the snowy wastes of Antarctica, scientists have picked up meteorites that almost certainly came from the moon and Mars. And near St. Gallen, Switzerland, there was discovered a 22-centimeter block of Malm limestone that was apparently ejected from the Ries impact crater, almost 200 kilometers away, about 15 million years ago. We know all of these rocks are impact debris because they contain shatter cones indicating a violent origin. Not only did these bits of debris confound expectations, but their shatter cones implied shock-wave pressures far too low to achieve lunar and Martian escape velocities, or even the velocity necessary to propel that chunk of Malm limestone 200 kilometers. Something was wrong somewhere. It has turned out that shock-wave theory had been misapplied. It is not the pressure that is important in ejecting bits of debris from around the impact site, but rather it is the pressure gradient. Anomaly extirpated!

The crystalline sheets, perhaps kilometers in thickness, were forcibly shoved hundreds of kilometers over sedimentary deposits during continental collisions -- so the theory goes. One such crystalline sheet is under the Southern Appalachians. Seismic data say it is about 10 kilometers thick and was pushed westward some 225 kilometers. If it seems intuitively impossible for such a thin sheet to remain intact during 225kilometers of shoving over other rocks, consider a similar sheet in the Basin and Range province of Utah. This sheet was pulled down an inclined fault without coming apart! These sliding sheets with remarkable structural integrities are required to explain what geophysicists see in the seismic reflections; namely, transparent zones of crystalline rock sitting on top of rocks that return strong reflections typical of layered sedimentary strata. However, one such situation in Arizona was explored with a drill bit. When the upper crystalline layer was penetrated, the drill found only more crystalline rocks, nothing sedimentary. In fact, the crystalline rock was not layered and was homogeneous. Thus, the source of the misleading seismic reflections is unknown.

The ecosystems clustered around the deep-sea vents and the bacteria found in deep aquifers demonstrate that the sun is not essential to life -- chemical energy does just fine. In fact, the domain of chemosynthetic life has now been extended to a Romanian cave that has apparently been almost completely sealed off from surface influences for 5.5 million years. Air does leak in through tiny cracks, and water partially fills the cave. What is most remarkable in this sunless, sealed ecosystem is its biodiversity: 48 animal species, including 33 brand-new species. The roster includes isopods, a millipede, a centipede, a water scorpion, and a leech. Of course, bacteria and fungi thrive there, too. In contrast to unsealed caves, where insects, bats, and other sources of food filter in from the surface, life in the Romanian cave seems to derive entirely from hydrogen sulfide present in the cave's rocks. This compound is consumed by microorganisms, which are then grazed by cave occupants higher up the food chain. A NASA scientist has called Movile cave a "Mars analog site." And indeed it might be, for Mars has plenty of rocks and subsurface water. (Skinrud, E.; "Romanian Cave Contains Novel Ecosystem," Science News, 149: 405, ...

Well, it seems that seismologists may have discovered a previously unread chapter or two deep beneath the continental United States, in the guise of extensive stratified rocks in the Precambrian basement: "The extent of the layered rocks became evident last summer as the Consortium for Continental Reflection Profiling (COCORP) completed a major deep seismic reflection traverse across Ohio, Indiana, Illinois, and part of Missouri. The survey was conducted partly because industrial seismic data and studies by the Illinois Geological Survey showed basement layering in southern Illinois, partly because earlier COCORP surveys also showed such layering in Oklahoma and Texas, and partly because COCORP's broad program calls for comprehensive exploration of the entire continental basement of the United States. "Although the composition and precise age of the Precambrian rocks are yet to be determined, their seismic reflection character suggests a sedimentary assemblage, at least in part. These layers occur within the Proterozoic Granite-Rhyolite province, where drilling typically recovers undeformed granite or rhyolite with ages of 1.3 to 1.5 b.y .

But it is not the rock art that is controversial about Pedra Furada; it is the 595 pieces of quartz selected by French archeologist N. Guidon. These bits of stone closely resemble humancrafted choppers, scrapers, and cutting tools. Indeed, if they had been found in more recent deposits, they would have been judged "man-made" by everyone. The trouble is that Guidon has dated them at 50,000 BP - a date mainstream archeologists cannot swallow.

They are "geofacts, not artifacts. They were created when quartzite rocks were released by erosion and fell off cliffs to be smashed upon impact below. Gravity and not the human hand broke the quartz into pieces that just happen to look like prehistoric tools. F. Parenti, a coworker of Guidon, has tried to exorcise the geofact argument, which is used wherever tools are "too old", by showing that the 595 pieces of quartz have characteristics quite unlike those created by natural flaking.

The usual explanation is that the layers of older rocks were thrust parallel to the bedding planes over the top of the layers of younger rock, sometimes for hundreds of miles. So numerous are these instances of inverted strata that a new branch of geology called Thin-Skinned Tectonics is arising to handle them. The present article deals with the complex stratigraphy in the Western Arbuckle Mountains in southern Oklahoma. Here are located many examples of old-on-young rock as well as completely inverted stratigraphic members. Much at-tention is paid to the evidence of sliding between beds (breccia, small overfolds, etc.). Some excellent photos of these contact planes are presented.

There one finds good-sized rocks at the ends of long tracks they have made when some force has propelled them across the flat playa surface. What has moved these rocks, some of which weigh 700 pounds? The current consensus holds that wind is the motive force, but that it is inadequate to move the rocks directly. Instead, the wind acts upon sheets of ice in which the rocks are frozen. As these sheets of ice are moved across the playa, the keels of the frozen-in rocks leave those curious trails that have intrigued Forteans for many decades.

It turns out in the end that a sweeping interpretation of this "Tiny Mystery" is called into question, but the mystery itself, like the smile on the Cheshire cat, remains. The "Tiny Mystery" is the existence of radiohalos from polonium-210, -214, and -218 in some biotites (micas), sans any detectable precursory uranium or halos thereof. Since the half-lives of the polonium isotopes are 138.4 days, 0.000164 second, and 3.04 minutes, respectively, it is certainly perplexing how the polonium halos got where they are! According to geological thinking, the igneous rocks containing the biotites must have been molten for a good deal longer than 138 days, thus destroying halos of short-lived isotopes. R.V . Gentry, a creationist, thinks that the polonium isotopes are primordial -- created by God some 6,000 years ago, in situ and without precursors. The rocks displaying the halos would, therefore, be among the oldest rocks on earth. What Wakefield does is exxamine the geology of some of the sites from which Gentry obtained his biotite samples. Basically, he finds that the supposedly primordial rocks are often just dikes and veins that were formed much later than the earth's oldest rocks.

Morris, an authority on prehistoric rock art, has contributed an article comparing the cup-and-ring motif, as found in Great Britain, with that found in North America. Since this stereotype motif decorates the rocks of all continents, save Antarctica, and since the hey-day of cup-and-ring engraving was 3-5 millennia ago, this unique design suggests the worldwide diffusion of culture thousands of years ago. A cup-and-ring engraving consists of a hollow or cup anywhere from 4 to 30 inches in diameter, surrounded by 1 to 9 rings. The rings may be gapped, with a narrow groove running through the gaps from the outside. (See the illustration,) Cups-and-rings have been found at over 700 sites in Great Britain. Most date between 2200 and 1600 B.C . The cup-and-ring is much rarer in the States. A few are known from Alabama, California, Georgia, Hawaii, Texas, and doubtless other states. In contrast to the ...

Waller's acoustical measurements at ancient rock-art sites in Europe, North America, and Australia. Waller claimed that some rock art was intentionally placed where echos from the walls are not only exceptionally loud but are also qualitatively related to the art's subject matter, such as running hoofed animals. The Newgrange chamber, with acoustical nodes and antinodes. Antinode occur at the chamber's stone walls. In a similar venture, R.G . Jahn et al have taken sound generators and meters into the chambers of six ancient structures and measured their acoustical properties. The sites selected were: Wayland's Smithy, Chun Quoit, and Cairn Euny, all in the U.K .; Newgrange, and Cairns L and I, Carbane West, all in Ireland. All of these sites date back to about 3,500 BC. The chambers were all bounded by roughly hewn stones, but they had very different configurations. Newgrange was cruciform (see sketch); others were rectangular, beehive, and petalshaped. Quoting the abstract from the Princeton report, here is what the acoustical surveys found: "Rudimentary acoustical measurements performed inside six diverse Neolithic and Iron Age structures revealed that each sustained a strong resonance at a frequency between 95 and 120 Hz (wavelength about 3m). Despite major differences in chamber shapes and sizes, the ...

In nature it sometimes occurs in long prisms of hexagonal cross section. In fact, ancient Micronesians quarried multiton basalt prisms to build their fantastic megalithic complex of 92 artificial islets at Nan Madol. (SF#45) The inhabitants of ancient Mesopotamia had no basalt quarries at hand. Indeed, building stone of any kind was exceedingly scarce. What the Mesopotamians of the second century B.C . did have in abundance was alluvial silt. From this unpromising material they were able to make their pottery, writing tablets, and art objects. However, for grinding grain and engineering structures they needed something harder and stronger. Their innovative solution was: artificial basalt made from silt. They simply melted the silt and let it cool slowly. Sounds simple, but three remarkable intellectual and technical advances were required: The Mesopotamians first had to recognize that silt could be melted. This could not have been obvious in 1000 BC. Next, they had to develop hightemperature (1 ,200 C) smelters that were much larger than those they used for metallurgical purposes. Finally, they had to discover that slow cooling was needed for the growth of large crystals in the cooling melt. (Of course, they had no microscopes to see the crystals. So, it had to have been something learned from experience.) That ...

In our more recent library searches, we have come across an old article that provides additional examples of the socalled Bradshaw paintings -- more of those graceful human forms with long, billowing tresses. Very out-ofplace in today's Outback. The same article adds an even more puzzling human representation to the burgeoning file of mysterious Australian art. It is a carving found in a cave of northwestern Australia. Here is the text accompanying the sketch. "Another cave introduced a fresh problem. Fronting it, high up on the vertical face of a cliff, and unreachable without mechanical aid, had been carved out of the solid stone a human head in profile, which I show. It was 2 feet long and 16 inches across, and 1 -inch thick; and I leave my hearers to say whether it is not a striking and distinguished face. It is absolutely different from the heads of modern Aborigines. The worn edges of the cameo, where it joined the rock-surface, seemed to mark a long interval since it was carved; the difficulty of carving it where it stood must have been immense -- unless, indeed, the rock face had been near the ground at the time, and the ground had worn away since - ...

... archeologists are of the opinion that they are dealing with a quarry. MG investigated the matter. We visited this alleged early quarry and discovered a few things! We thought it odd that that it's been classified as a Roman or Celtic quarry. "The site itself is located in the Sternenfels district about 25 km west of Pfortzheim/Baden-Wurttemberg. "The structure consists of: An almost central dome-hill laid in brick, surrounded by natural, hewn stones. The dome-hill (height: 15-18 m; length: 100 m; width: 60-80 m) was stacked blockwise with Keuper sandstones and clay slate. The structure's volume is estimated at about 60,000 cubic meters, which corresponds to about 100,000 tons of rock. The encompassing artificial rock walls are thought to have served as a quarry for the manufacture of the dome stratification. These rock walls were hewn artificially with tools after the quarrying of the dome stones...a place of worship? According to the map, this dome structure forms a connecting axis with other Celtic sites in this area." Summarizing additional data from the translation: (1 ) This is the largest pyramid in Europe; (2 ) The surrounding rock walls show tool marks, several petroglyphs, and Celtic symbols; and (3 ) It is suspected that this site might have been used for ritual purposes.

It is less well known that life's domain extends down much further. The hard rocks and strata of earth's crust -- seemingly sterile and inert -- are continuously being transformed by bacteria and other life forms. In fact, it was easy to find three examples of such processes from the literature collected from the past two months. Although the discoveries reported below may seem dull to anomalists ued to more exciting fare, it may well be that life from "inner space" has been and will be more important to humankind than life from "outer space," as implied in third item! Bacteria and placer gold. "Lacelike networks of micrometresize filiform gold associated with Alaskan placer gold particles are interpreted as low-temperature pseudomorphs of a Pedomicrobium -like budding bacterium. Submicron reproductive structures (hyphae) and other morphological features similar to those of Pedomicrobium occur as three-dimensional facsimiles in highpurity gold in and on placer gold particles from Lillian Creek, Alaska." In short, bacteria help create placer gold deposits. The author believes that bacterioform gold is widespread.

Martin quoted as saying: "If humans lived in the New World more than 12,000 years ago, there'd be no secret about it." This was from an article in which archeologists (some of them at least) were trying to roll forward the date at which humans entered the Americas from 12,000 to 11,500 years ago. In just a few months, we have collected four new items from the general scientific literature (not the U.S archeological literature!) that seem to be swimming against the current. The Meadowcroft Rockshelter . J.M . Adovasio and R.C . Carlisle, in a letter to Science, argue that better dating techniques have consistently pushed the date at which humans arrived in the New World. Using their own work at the Meadowcroft Rockshelter, in Pennsylvania, they cite many radiometric dates earlier than 12,000 years. At this Pennsylvania site, the six deepest dates definitely associated with cultural material indicate that humans were here 13,955 to 14,555 years ago.

... stands an enigmatic array of stone blocks. It "looks" like a wall; a human-built wall. It also "looks" old; perhaps 2,000 years old according to some. Who built it? Passions are running high in New Zealand, where three hypotheses are being advanced: The wall was built some 2,000 years ago by the first settlers of New Zealand, the Waitahas, who were subsequently nearly exterminated by the Maoris, who arrived only 800 years ago. There are political problems with this theory, for the Maoris insist they are the original New Zealanders and therefore are due compensation for lands expropriated by later Europeans. The wall is merely what's left of a sawmill built only 50 or so years ago. The wall is simply a natural rock formation that has happened to split neatly into rectangular blocks -- like those slabs of beach rock that comprise the controversial Bimini "road" in the Bahamas. Future study of the "wall" will doubtless narrow the list to one. Meanwhile, let's take a look at the wall itself. B. Brailsford, of Christchurch, has been the chief investigator of the Kaimanawa wall, aided by American D.H . Childress, and others. The stones that make up the wall are 4-ton blocks of ignimbrite, a soft volcanic rock that could have been easily dressed with stone tools. The wall is topped by a red beech tree 2.9 meters in circumference and over a meter of accumulated humus. According to Brailsford, who was interviewed by the Listener ...

The bubblings of Old Faithful geyser give rise to an enduring and engaging "harmonic tremor." As for the more "exotic" sources of seismic signals, they had an entire session devoted to them at the Fall 1996 meeting of the American Geophysical Union. Here are two of the unusual seismic events presented there. July 10, 1996. Yosemite National Park. "At 6:52 pm PDT Wednesday, July 10, 1996, a large block of granite, with an estimated mass of 80,000 to 184,000 tons, detached from the cliff between Washburn Point and Glacier Point, in Yosemite Valley. The rock mass subsequently launched from the cliff and free-fell ballistically an estimated 550 m before impacting approximately 30 meters from the base of the cliff in the Happy Isles area of the valley floor in Yosemite National Park...This rock fall was well recorded by 3 UC Berkeley (BDSN) and Caltech (TERRAscope) broadband seismographic stations and 15 shortperiod seismographic stations (operated by the USGS in Menlo Park and the University of Nevada, Reno).
