Lithic period in Mesoamerica

Paleo-Indians (also spelled Paleoindians) were the first peoples who entered and subsequently inhabited the Americas towards the end of the Late Pleistocene period. The word comes from the prefix paleo-, taken from , and "Indian", which has been historically used to refer to Indigenous peoples of the Americas. The term Paleo-Indian applies specifically to the lithic period in the Western Hemisphere and is distinct from the term Paleolithic.
