First evidence that "Clovis" people, the first confirmed human inhabitants of North America (only some 13,000 years ago) hunted and butchered the gomphothere, a pretty wierd, elephant-like beast that was part of the North American Pleistocene megafauna that disappeared very rapidly just about that time.
Wikipedia suggests gomphotheres may have survived in South America as recently as 400 CE (1600 years ago), and butchered remains had previously been confirmed at the Chilean early settlement site Monte Verde. So now you know.
