at the cusp of the Ice Age

At http://phys.org/print346399429.html … people were hunting horses and camels 13,300 years ago (in N America) – prior to the Younger Dryas event. For some reason the news release chooses to say they were living in the Ice Age – which isn't true. They were living in a warm period between the end of the Ice Age and the Younger Dryas. However, they were living in the very late Pleistocene – which I suppose is all part of the Ice Age, depending how accurate you might want to be. The horse and camel remains were  found near Calgary in Canada, on the rolling priaires. The kill site was near a point where animals could safely cross a river.
