The Fossil Lake Camelid Kill Site (35LK525) contained camelid bones (probably Camelops hesterenus). Typical representative: Camelops hesternus. The drop in sea level during the Ice Age caused the exposure of land that became known as the Bering Land Bridge or Beringia that linked the two landmasses.
