Archaeology study says humans were in North America 100,000 years earlier than we thought - Business Insider: Amongst the mastodon remains, the researchers found what they believe are bones that had been fashioned into hammer-stones and anvils — two types of tools that early humans used in Africa as early as 1.7 million years ago. And those objects showed wear-and-tear that the researchers say could not have been caused by geological processes.

"At many sites you have evidence that bones were used for hammers or anvils," says Richard Fullagar, an archaeologist at Australia's University of Wollongong. "What’s truly remarkable at this site is you can identify a particular hammer that was hit on a particular anvil."

Together, all of this data paints a picture that Fullagar calls "incontrovertible" evidence that humans were around at the time this mastodon died.
