This is the only thing I’ve learned: There’s only us. There’s no them. Despots and authoritarians need to make a “them” to have a straw man whom you are against. If you need to make an enemy of “them,” you’ve lost the spirit of us. - Ken Burns of PBS
cnc66luxury_boxIce 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 Mahaffy Cache, named for the owner of the property on which it was found, consists of 83 stone implements ranging from salad plate-sized, elegantly crafted bifacial knives and a unique tool resembling a double-bitted axe to small blades and flint scraps. Discovered in May 2008 by Brant Turney — head of a landscaping crew working on the Mahaffy property — the cache was unearthed with a shovel under about 18 inches of soil and was packed tightly into a hole about the size of a large shoebox. It appeared to have been untouched for thousands of years, Bamforth said.

All 83 artifacts were shipped to the anthropology Professor Robert Yohe of the Laboratory of Archaeological Science at California State, Bakersfield for protein residue tests that were funded by Mahaffy. The protein residue on the artifacts was tested against various animal anti-sera, a procedure similar to standard allergy tests and which can narrow positive reactions down to specific mammalian families, but not to genera or species.

One of the tools, a stunning, oval-shaped bifacial knife that had been sharpened all the way around, is almost exactly the same shape, size and width of an obsidian knife found in a Clovis cache known as the Fenn Cache from south of Yellowstone National Park, said Bamforth. "Except for the raw material, they are almost identical," he said. "I wouldn't stake my reputation on it, but I could almost imagine the same person making both tools."
