Microwear analyses of artifacts, dated to 100,000 B.P., from Pedra Furada:

Pedra Furada: a revision
Niede Guidon, Summary
"The main purpose of the article is to publish the photos made in the laboratory of the Texas & the M University, of the oldest líticas parts of the Pedra Furada, with a dating TL of 100.000 years, with the commentaries from the Prof. Robson Bonnichsen." (Translated with Babylon)

Presented at:
II INTERNATIONAL SYMPOSIUM
SERRA DA CAPIVARA NATIONAL PARK
PIAUÍ, BRAZIL
DECEMBER 16 TO 21 OF 2006
In 1993 the Foundation Museu do Homem Americano invited specialists of various countries to its headquarter in São Raimundo Nonato, Piauí, in order to evaluate the data known so far on the prehistoric peopling of the Americas.
Since then, fresh discoveries, analyses using new technologies and recent methods of dating created an important collection of new data. Consequently, complementary research work was realized at Serra da Capivara National Park. As an example we cite the data on the site Boqueirão da Pedra Furada which, by applying new C-14 techniques and thermoluminescence dating gives us a space of time of 100.000 years. There are also positive results of analyses carried out by electronic microscope, at Texas A & M University on the wear marks of lithic tools, dating back between 57.000 and 100.000 years. Other examples are the Topper site on the coast of South Carolina, as well as dates and traces in Mexico. We have new discoveries and fresh data in the Americas which deserve an actual reflection.
The Foundation Museu do Homem Americano, the Federal University Vale do São Francisco and the Department of Post-Graduation in Archaeology and the Preservation of our Patrimony of the Federal University of Pernambuco are organizing a Symposium on December 16 - 21, 2006 when interdisciplinary specialists dedicated to the problem of the peopling of the Americas will meet.
The objective of this symposium is to analyse the data available and to outline the version 2006 of the subject. The final synthesis will permit to define the items not yet fully explored in order to establish an international platform which will lead the research to a reconciliation by explaining the current problems and elaborating a coherent theory based on the actual information.
It is with great pleasure that we invite you to take part in this discussion. As soon as you confirm your interest, we will let you have the documents for your inscription and the details of your trip to Serra da Capivara National Park.
Kind regards,
Niède Guidon.

Chris Hardaker posted these at Archaeologica via Michelle. The pics were from your collection. Many thanks Charlie. Nice discussion at Maat also. |

Chris posted those at the Author of the Month forum at Graham Hancock's message boards. I also replied with Robert Lassen's reply which was not positive but he had actually examined some of the Pedra Furada cobbles while they were on loan at Texas A&M. Admitting he was no expert on wear use analysis, he noted that the cobbles he saw had cones all over the surface instead of concentrated on the flaked use edges. He thought that was the result of spalling from falling from a height. This was the same opinion Mike Collins gave when he went to Pedra Furada to examine the evidence. Chris on the other mentioned that quartzite is so hard that you don't see similar cones in river cobbles subjected to a great deal of abuse in stream transport. Chris also said that Robert may have been looking at cones in the cortex, a much softer "rind" on the outer surfaces. The conclusions of the experts on both sides of the Pedra Furada controversy are almost the direct opposite of one another but I lean toward Niede Guidon. The opposition, including Mike Collins and David Meltzer still won't accept the hearths as human products despite their scenario of natural fires is directly contradicted by the lack of evidence or even plausibility. Niede's students searched diligently for evidence of natural fires in the surrounding area coeval with the hearths and found zilch. The fact that the site is well up the canyon wall away from any source of natural fires puts the debunkers in the same sinking boat as those maintaining the barbecued mammoths of Santa Rosa are the result of naturally burning packrat nests. The fact that no Pleistocene packrats were present at that time has no bearing on the their argument. Pedra Furada is beginning to look a lot like Hueyatlaco in terms of the tactics used. _________________ David Campbell

The credit is due to Chris. He got permission to use the images and provided them to me. I simply uploaded them and provided links.
Thanks! _________________ Charlie Hatchett

Charlie, I noticed that Min was asking if iron oxide was supposed to be non-magnetic over on Archaeologica and you might refer him to our earlier discussions here on your magnetic artifacts from Brushy Creek. Short answer is that the massive deposits of iron oxide up here on the Red River display no magnetic properties that I've ever been able to detect. And that goes for the low grade iron ore southeast of here according to Mr. Turner, a retired engineer turned avocational archaeologist who is considered something of an authority on ferruginous sandstone (iron ore) artifacts found up here. _________________ David Campbell

My mistake. In rereading the discussion at Archaeologica, it was Digit who posed the magnetic iron oxide question. He states that the earth naturally magnetizes iron oxide but I have not found that to be the case locally. In fact some iron oxide spherules I picked up at Bonham State Park which were quite heavy were disappointingly non-magnetic. I thought I had a fortune in meteorites on my hands but I fear they are just additions to my extensive collection of weird but worthless rocks. _________________ David Campbell

Yeah Dave, without Charlie Archaeologica is woefully short of knowledge about lithics right now. I've been scanning posts from other websites to help with the discussion about this new batch of pics from Mexico.
But it's hard to get folks excited about this unless they can really understand the connection to the First Americans. That's what keeps some of us wanting to learn more about it. |

I've had the same experience, David. I've never found a piece of iron ore, which mainly comes in the form of iron sulfide (pyrite) here, that displays magnetic properties. _________________ Charlie Hatchett

Min has a good eye, Beags. If he would sit down and study different assemblages, he'd have no problem becoming very good at artifact analyses. _________________ Charlie Hatchett
