ICHTHYOSAUR EVOLUTION

During the early Triassic period, ichthyosaurs evolved from a group of unidentified land reptiles that returned to the sea.

They were particularly abundant in the later Triassic and early Jurassic periods before being replaced as a premier aquatic predator by another marine reptilian group, the Plesiosauria, in the later Jurassic and Cretaceous periods.
