Paleo-Indians were the first peoples who entered and subsequently inhabited the Americas towards the end of the Late Pleistocene period. The prefix paleo- comes from the Ancient Greek adjective: παλαιός, romanized: palaiós, lit. 'old; ancient'. The term Paleo-Indians applies specifically to the lithic period in the Western Hemisphere and is distinct from the term Paleolithic.
The Paleo-Indians, also known as the Lithic peoples, are the earliest known settlers of the Americas; the period's name, the Lithic stage, derives from the appearance of lithic flaked stone tools.
The Mammut americanum (American mastodon) became extinct around 12,000–9,000 years ago due to human-related activities, climate change, or a combination of both. See Quaternary extinction event and Holocene extinction.
