At many of these Camelops sites, no fossils have been found of carcasses that were evidently processed, but rather small fragments and pieces of remains. Researchers originally thought that Camelops species were in fact hunted and butchered by early humans in North America because of these reasons: the fragmenting of bones into shapes that look like tools, damage or weathering of the “working” edge of said tools, having attributes that were similar to the making of chopping tools, and scarred fragments from possible chopping tools.[1] Further examination showed, though, that these assumptions were misguided, and that while humans did coexist and associate with Camelops, human use has yet to be completely proven as the sole cause of extinction.[13]
