130,700-year-old mastodon bones push back arrival in Americas
Shattered mastodon remains from a southern California site show patterns of bone breakage and cobble tool use that researchers interpret as evidence of early human activity dating to about 130,700 years ago. If confirmed, this could rewrite timelines of human migration to North America, suggesting pre-ice bridge crossings or seafaring.
