PaleolithicThe Paleolithic or Palaeolithic (ˌpeɪl-,_ˌpæliəʊˈlɪθɪk), also called the Old Stone Age (from Greek: παλαιός palaios, "old" and λίθος lithos, "stone"), is a period in human prehistory that is distinguished by the original development of stone tools, and which represents almost the entire period of human prehistoric technology. It extends from the earliest known use of stone tools by hominins, 3.3 million years ago, to the end of the Pleistocene, 11,650 cal BP.
CougarThe cougar (Puma concolor) (ˈkuːˌgər, KOO-gər), also known as the puma, mountain lion, catamount or panther, is a large cat native to the Americas, second only in size to the stockier jaguar. They are not technically grouped with the “true” big cats, as they are slightly smaller than other big cats, and they lack the vocal physiology to roar (such as with lions, tigers, leopards and jaguars). Its range spans from the Canadian Provinces of the Yukon, British Columbia and Alberta, the Rocky Mountains and areas to the Western United States.
