1.3 Million Year Old Footprints of Modern Homo Sapiens In Mexico



"Our work at Hueyatlaco has been rejected by most archaeologists because it contradicts that theory [evolution], period." -- Virginia Steen-McIntyre, tephrochronologist, March 30th 1981

"The problem as I see it is much bigger than Hueyatlaco. It concerns the manipulation of scientific thought and the suppression of 'Enigmatic Data,' data that challenges the prevailing mode of thinking." -- Virginia Steen-McIntyre, tephrochronologist, March 30th 1981

Renne, P.R., et al., Geochronology: Age of Mexican Ash with Alleged 'Footprints', Nature, 438, E7-E8, Dec 2005

A report of human footprints preserved in 40,000-year-old volcanic ash near Puebla, Mexico (http://www.royalsoc.ac.uk/exhibit.asp?id=3616&tip=1), was the subject of a press conference that stirred international media attention. If the claims (http://www.mexicanfootprints.co.uk) of Gonzalez et al. are valid, prevailing theories about the timing of human migration into the Americas would need significant revision. Here we show by 40Ar/39Ar dating and corroborating palaeomagnetic data that the basaltic tuff on which the purported footprints are found is 1.30 +/- 0.03 million years old.
Feinberg, J.M., et al., Age Constraints On Alleged "Footprints" Preserved In the Xalnene Tuff Near Puebla Mexico, Geology, Volume 37, Number 3, Pages 267-270, Mar 2009

Impressions in a basaltic tuff located around Valsequillo Reservoir near Puebla, Mexico, have been interpreted as human and animal footprints along an ancient lakeshore, and are cited as evidence of the presence of humans in North America at 40 ka B.P. In this paper, we present new data that challenge this interpretation. Paleomagnetic analyses of the Xalnene Tuff, and lavas from the volcano from which it erupted, yield fully reversed magnetic polarities, indicating that the tuff was deposited prior to the last geomagnetic reversal (the Brunhes-Matuyama ca. 790 ka). 40Ar/39Ar dating of Xalnene lapilli and lava from the source volcano yields indistinguishable ages of ~1.3 Ma, consistent with a period of reversed magnetic polarity (C1r.2r).

I wonder why that "modern homo sapien" wasn't wearing shoes?

OilIsMastery said...

Do you also wonder why modern homo sapiens don't wear shoes today in 2009?

Quantum_Flux said...

Obviously that guy has a fetish with not wearing shoes.

OilIsMastery said...

Now do you believe me when I say the ancients were more advanced than people living in 2009?

OIM,

He does not wear shoes because he ran out of leather after covering his tool.

KV said...

OIM,

Besides Mexical don't do that! May be you might want to check some Maya stone carvings...

KV said...

OIM,

Finally, just let me know the city you are in, so I can avoid you strutting along without shoes and the rest.

When weighed against the volume of evidence that mankind is younger than 1.3 my old, this fades into background noise.

There is an explanation other than the bullshit Vedic Creationism that Oils spouts.

The easiest is that the prints are not human, but that remains to be seen.

The evidence from paleomagnetic analysis and 40Ar/39Ar dating show that the Xalnene Tuff is not 40 ka old. Instead, our data show unambiguously that the Xalnene Tuff is 1.3 Ma. If the marks identified by González et al. (2006a) were of human origin, then they would probably belong to early Homo erectus (Antón and Swisher, 2004). This is unlikely, based on the known geographic distribution of these early hominids (Antón and Swisher, 2004) and the genetic and archaeological evidence for the peopling of the Americas (Goebel et al., 2008). The marks observed by González et al. (2006a) were found in a stone quarry and are more likely to represent marks left behind from this quarrying, which were later enhanced by weathering and erosion.

There you go. Not footprints at all.

Nice try, Oils. Got anything else up there?

That guy could hydraulically jack up a vehicle.

Jeffery,

Unfortunately for you the footprints were found near the the 200,000+ year old city of Hueyatlaco where Homo sapiens skeletons and artifacts were found with extinct Pleistocene fauna.

"I determined fission-track ages on zircons from two of the tephra units overlying the artifacted beds. The Hueyatlaco ash yielded a zircon fission-track age of 370,000+/-200,000 years, and the Tetela brown mud yielded an age of 600,000+/-340,000 years. There is a 96 percent chance that the true age of these tephras lie within the range defined by the age and the plus or minus value. Now, there were four different geological dating techniques that suggested a far greater antiquity to the artifacts than anyone in the archaeological community wanted to admit." -- Charles W. Naeser, chemist, April 2007

Jeffery,

"The marks observed by González et al. (2006a) were found in a stone quarry and are more likely to represent marks left behind from this quarrying, which were later enhanced by weathering and erosion."

Who was quarrying stone 1 million years ago if not Homo sapiens?

The Zeta reticulans?

Evidence please.

"Not footprints at all."

Are you blind?

Raptor Lewis said...

Two possibilities exist: Homo erectus or Homo sapiens.

Jefferey- This change in thinking does not prove "Creationism" as you incorrectly claim. It merely suggests that we may have been wrong about when we actually arose as a species.

Quantum Flux- The term "modern" refers to physiology similar to us today and not in the context we normally think of. The first humans had a slightly different build than we do today. That is the difference.

Raptor Lewis said...

Homo erectus DID have the ability for stone carving and possibly some quarrying. So, don't dismiss Jefferey completely, OiM.

Jeffery- If those prints are an example of "quarrying," then what's with the shape? Hmm? If there was any quarrying done, and if you claim "erosion," then the prints would be GONE! Instead, these tracks fossilized.

OilIsMastery said...

Mr. Lewis,

In response to: "Homo erectus DID have the ability for stone carving and possibly some quarrying. So, don't dismiss Jefferey completely, OiM."

I don't discount Jeffery completely, just most of the time. You are correct in saying that it could possibly be an erectus foot, and you are correct in saying they are more like us than most people assume, the only problem is: we don't know what an erctus foot looked like. So the only foot we know that's like a modern Homo sapiens sapiens foot print is in fact Homo sapiens sapiens.

Arie Sheyn said...

I'm the only person here would would take their shoes off if they had to wade in a giant patch of volcanic ash mud?

Don't people pay big money to soak in this type of stuff at spas?

Perhaps going barefoot in this "mud" not only prolonged the life of shoes, but also felt therapeutic... whose feet wouldn't hurt if they had to walk everywhere?

One of Oil's central themes is that human kind predates the dinosaurs. It's like strawberry ice cream to him.

Any post involving the lifetime and/or origin of our species is aimed at furthering this particular nonsense of his.

He doesn't buy evolution. He thinks that all speciation is the result of artificial selection.

Clearly, this thinking underlay this post as well.

Raptor Lewis said...

OiM- That's true. We DON'T know exactly what their foot looked like but their foot design of most species of the genus Homo share a similar foot design. So, I believe it's either H. sapiens sapiens or H. erectus.

Raptor Lewis said...

Jeffery- Actually, we really don't know how far our species goes back, so don't jump the gun yet until we find more fossil evidence. I believe it may be H. sapiens, that or H. erectus.

Another thing, Jeffery, YOU'RE the one ignoring possibilities and evidence! Apparently, you're not just ignorant but a hypocrite as well.
