parfive Rich, So they found some rounds rocks & a few broken bones, not that convincing IMHO. If they found cut marks on the bones & some flaked tools that would be more definitive. BTW, what are the earliest flaked tools that have been found?

[wampidytoo]

The last I read flaked tools were recently found that are over a million years old. I may have saved the source but I have pretty much quit saving sources because most people on here either won't read them or won't believe them after they read them. Too many boxed in brains on here that consider everything from the past is written in stone and could not possibly be wrong.

Well shoot, Louis Leakey found Homo habilis and other ancient hominids' flake tools and crude hand axes and choppers in Olduvai Gorge in Africa that were like 1.9 million years old. Buddy of mine went there to visit his son and he brought me back a couple of hand axes but somehow they didn't make the Texas move. Really crude and , to me, it took quite a lot of imagination to make them tools but I guess the Leakey research is very well accepted. I did read somewhere they have found stuff here in the Americas that goes back further than they thought too but I don't know how well accepted that is. I think accepted date of oldest man find in the Americas is something like 40-50,000 years old but there are getting to be a few folks thinking man go here much sooner..Mel

The first article rich presents puts them in San Diego at 130,000 years

Pretty cool if more finds can be made to corroborate it. I'm always a little skeptical about some of the things folks call tools. Based on my own experience, it is good to be skeptical about one off discoveries too. Here where I live, the ranch is full of Amerind dart points 3-4000 years old that are sitting on the surface adjacent to relatively recent arrowheads due to soil erosion which puts things in association that do not belong in association. Picture mastodon bones sitting eroded in a ravine or on the surface and water washing younger stone materials into association and then the whole mixed mess being buried over time. Looks like the stuff belongs together but they do not. And I gotta say lots of naturally occurring round rocks and flakes occur and resemble artifacts but are not. Of course, I'm the kind of guy who likes too see the mastodon bone with a point sticking out of it. Now that would be conclusive evidence *L*....Mel

Awe c'mon now, us brilliant people have all the ages defined. Why this here Silurian sea scorpion fossil is definitely 410-440 million years old. Possible. Can't deny...
They have difficulty dating an item from recorded history that is 1000 years old.
Devonian fossils found on top of Silurian and Ordovician fossils found below Silurian- yes - maybe, sounds feasible. But 420 million years ago ? Get real/laughable.
Perhaps 420 million +/_ 400 million. A lot of shit can happen in 20 million years, a million years for that matter.

Master the last ice age first. 4000 years ago ? 8000 years ago ? 20,000 years ago ? One million years is divisible by 10,000 years a hundred times. Do the numbers. See the absurdity.

To think they had the balls to teach us this crap in elementary school. Where's that science teacher ?

Did I read somewhere that we ate the mastodon or wooly mammoth into extinction? Apparently we stuck them with spears and then tracked them until they died. A lot of them got away and died later. I think the last of them.were in Florida? He my memory ain't right so somebody please straighten me out.

There remains are common in Florida. Repeatedly found in the layer containing spearheads. And a plethora of ice age mammals.
Long list of mammals in same layer. Made the Serengeti's of Africa look void of mammals. Maybe 5 variations of saber tooth cats alone.
Thanks to Florida's chemistry mineralization of mammal bones it preserved the ice age mammals well.
Florida ice age mammal bone collectors have detailed records and volumes of shared information on what bone goes to which animal.

from what I gather, it was probably/possibly an impact or near earth explosion in northern N America that was the primary cause of the major die off of all large animals in N America. Some vegetation will come back fairly quickly but starvation happens pretty fast.
