Mastodon meal scraps revise US prehistory
Stone tools and bones from a butchered mastodon, found at the bottom of a river in Florida, are shaking up the known history of humans in the region.
A four-year investigation of the site has firmly concluded that humans lived there and, in particular, made a meal of a mastodon 14,550 years ago.
This is more than a millennium earlier than humans were thought to have settled the south-eastern US.
The findings are reported in the open access journal Science Advances.
They reinforce the idea that humans settled the Americas well before the Clovis people arrived about 13,000 years ago. For many years, the Clovis were thought to have been "the first Americans".
In fact, the mastadon tusk that is the centrepiece of the Florida haul, complete with apparent cut marks and accompanying tools, was first found and dated in the 1980s - but the discovery gained little traction.
"[It] was an impossible date for the scientific community to accept at the time, because it was well accepted that the Americas were colonised by the Clovis people, who arrived on the continent over the Bering land bridge no longer than 13,500 years ago at the oldest," said Jessi Halligan, lead author of the new study and assistant professor of anthropology at Florida State University.
That view, however, has gradually been revised as more and more evidence accumulates that humans arrived thousands of years earlier - perhaps as early as 16,000 years ago, when the last ice age was only beginning to thaw.
But that evidence remains scarce, and the new study provides the best evidence yet for such a presence in the south-east of the US.

I'd be interested to hear the Creationist explanation.
