Mastodon markings

It looks like a history of human migration around the world will have to be completely rewritten as stone tool marks on mastodon remains point out to hominid presence in North America some 115,000 years earlier than previously thought.

It is generally accepted than modern humans arrived in New World around 15.000 years ago by crossing from Siberia into Alaska over Bering land bridge when sea levels were much lower than today.

“Teeth and bones of the elephant-like creature unmistakably modified by human hands, along with stone hammers and anvils, leave no doubt that some species of early human feasted on its carcass, they reported in the journal Nature.

Discovered in 1992 during construction work to expand an expressway, the bone fragments “show clear signs of having been deliberately broken by humans with manual dexterity,” said lead author Steve Holen, director of research at the Center for American Paleolithic Research.”
