Before their formal designation as state reptiles, Florida's alligator, Maryland's terrapin, and Texas's ...
During the Triassic, corals were rare in North America. Nevertheless, some were present on the west coast, although these corals did not congregate into reefs. [49] Ichthyosaurs were one of the most important groups of marine reptiles during the Triassic. Important ichthyosaur fossils of this age were preserved in Nevada. [50]
