Wait, is that BC or AD...You aren't going to quibble about a mere 50,000 years, are you?

Yup. To paraphrase an English football chant - Charlie is our leader. Preclovis wise, he looks like he's coming up with the goods. Plus I've heard that only a fool would pick an argument with a Texan.stan wrote:I'm impressed by the way everyone is pitching in to help our friend Texas Charlie.

True, Bruce. That is the club interpretation. Can you shed light on any difficulties with their interpretations. I'm always ready to learn.Charlie, that's what the club has come with. I just love all the uplifting that went on! And what the hell is terrane accredition, that's a new one for me
I think it's when two tectonic plates collide, and build up terrane.And what the hell is terrane accredition
Me too!! I think we're all learning here!!I'm impressed by the way everyone is pitching in to help our friend Texas Charlie.

Right. The Hueyatlaco artifacts rest upon the Xalnene, which rests, uncomformably, upon the limestone bedrock. Waters and Gonzales disagree on the Xalnene dating (1,300,000 B.P. vs. 40,000 B.P.). The kicker, though, is the Hueyatlaco Ash, at the Hueyatlaco Site, securely covers the artifacts and the Xalnene (second diagram). At Hueyatlaco, no one has come up with a lower date than 200,000 B.P. for the Hueyatlaco Ash. Thus, it seems reasonable to assume the Xalnene is older than 200,000 B.P.Charlie,
looks like those artifacts are right on top of an "unconformitie" which I guess means they don't know how that layer got there, right?
they summariseIf the markings on the exposed surface of the tuff are human footprints recorded soon after its eruption, the obvious implication is that they are 1.3 million years old.
Note that the authors feel no need to reference the _consideration_ that the possiblity is "extremely remote".If the markings are hominid footprints, they would be most likely to have been made by a hominid that existed before H. sapiens,
and we consider such a possibility to be extremely remote. We conclude that the identification of any of these features as syndepositional hominid footprints is erroneous.
Ah, yes....meet Homo Erectus....If the markings are hominid footprints,
they would be most likely to have been made
by a hominid that existed before H. sapiens,
and we consider such a possibility to be
extremely remote.
http://en.wikipedia.org/wiki/Homo_erectusFossilized remains dating to 1.8 and 1.0 million years old have been found in Africa (e.g., Lake Turkana and Olduvai Gorge), Europe (Georgia), Indonesia (e.g., Sangiran and Trinil), and China (e.g., Lantian). H. erectus remains an important hominin since it is believed to be the first to leave Africa.
The authors explain away the problem of H. erectus not being in America at such an early date by conveniently isolating them in Asia. How the last African dispersal selectively picks up the American lice and transports them to the Americas to the ensuing, total lack of surviving lice in Asia is beyond me ... how did they do that? Ancient germ wars?American mystery
The paper's authors agree and instead suggest that it may fit a more ancient separation between the human lineage that led to Homo sapiens and one that led to a species known as Homo erectus.
This split probably occurred anywhere between 1.8 million years ago and 1.2 million years ago.
"If you do the calibrations on the split, that's the only one that makes any sense," co-author Dr Vince Smith, of the University of Illinois at Urbana-Champaign, told BBC News.
By one million years ago, Homo erectus was established both in Africa and in East Asia. In Asia, erectus could have remained isolated until a second wave of migration out of Africa brought modern humans into contact with them - and their lice - after 100,000 years ago.
I have got to say this post has got me thinking. Pretty much a no-brainer for "the flood" I would have thought?http://www.iht.com/articles/2006/11/14/news/meteor.php

For all you coastal dwellers. Don't know if these would cause 40 days and 40 nights of rain but certainly would cause a memborable event-for the survivors
