Abstract
The Triassic is a geological period that extended from about 250 to 200 Mya (million years ago). As the first period of the Mesozoic Era, the Triassic follows the Permian and is followed by the Jurassic. Both the start and end of the Triassic are marked by major extinction events. The extinction event that closed the Triassic Period has recently been more accurately dated, but as with most older geological periods, the rock beds that define the start and end are well identified, but the exact dates of the start and end of the period are uncertain by a few million years. During the Triassic, both marine and continental life show an adaptive radiation beginning from the starkly impoverished biosphere that followed the Permian - Triassic vertebrates, the pterosaurs, evolved during the Triassic. extinction. Corals of the hexacorallia group made their first appearance.
