Ice Age Camels Butchered in Colorado

Stone tools found in Boulder, Colorado were used to butcher camels and horses 13,000 years ago, before the beasts became extinct in the region.

A new biochemical analysis of a rare Clovis-era stone tools was done at the University of Colorado at Boulder. It is the first study to identify protein residue from extinct camels on North American stone tools and only the second to identify horse protein residue on a Clovis-age tool, said CU-Boulder Anthropology Professor Douglas Bamforth, who led the work.

The Clovis culture is believed by many archaeologists to coincide with the time the first Americans arrived on the continent from Asia via the Bering Land Bridge, about 13,000 to 13,500 years ago.
