26 set 25200000 ano antes da era comum - Triassic Period

Descrição:

The oceans had been massively depopulated by the Permian Extinction when as many as 95 percent of extant marine genera were wiped out by high carbon dioxide levels. Climate was generally very dry over much of Pangaea with very hot summers and cold winters in the continental interior. Plants and insects did not go through any extensive evolutionary advances during the Triassic. Due to the dry climate, the interior of Pangaea was mostly desert.
