Beginning 538.8 million years ago (Ma), it succeeds the Neoproterozoic (the last era of the Proterozoic Eon) and ends 251.9 Ma at the start of the Mesozoic Er
There were a few Paleo-Indian cultures, distinctive by the size of the tools they used and the animals they hunted. People in the first, Clovis complex period, had large tools to hunt the megafauna animals of the early Paleo-Indian period. [4] With time, the climate warmed again and lakes and savannas receded.
Irish elk.

Another huge animal of this group was Uintatherium, with skull length of 76 cm (30 in), 1.5 m (4 ft 11 in) tall at the shoulder, [143] 4 m (13 ft) in length and 2.25 t (2.48 short tons), the size of a rhinoceros. [144] Despite their large size, Eobasileus as well as Uintatherium had a very small brain. [143] [144]
Paleobotany. Paleobotany, also spelled as palaeobotany, is the branch of botany dealing with the recovery and identification of plant remains from geological contexts, and their use for the biological reconstruction of past environments (paleogeography), and the evolutionary history of plants, with a bearing upon the evolution of life in general.
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 ...
