Learn about life through time... Triassic

The Triassic period (208-245 MYA) began the Mesozoic era - the age of the dinosaurs. The enormous supercontinent Pangaea began to break up into smaller continents, while large inland seas formed and a warm climate prevailed.

Life began to revive from the massive extinction at the end of the Permian period. In the sea, ammonites and other molluscs flourished alongside various types of echinoderm. Marine reptiles such as ichthyosaurs and plesiosaurs appeared. On land mammals evolved, and the first small dinosaurs appeared alongside pterosaurs. Insects diversified and evergreen trees were abundant.
