Triassic Period , in geologic time is the first period within the Mesozoic Era . The Triassic is the first and shortest period of the Mesozoic Era. Both the start and end of the period are marked by major extinction events. It began 251 million years ago which is at the end of the Permian Period , and ended 199 million years ago, that was followed by the Jurassic Period .
The Triassic Period was labeled as the beginning of major changes. According to Logan (n.d.) it took place throughout the Mesozoic Era, specifically in the distribution of continents, the evolution of life, and the geographic division of living things.
At the beginning of the Triassic, most of the major landmasses were concentrated in the giant C-shaped supercontinent known as Pangaea. Terrestrial climate was predominantly dry over much of Pangaea with very hot summers and cold winters in the continental interior. According to Bagley(2014), a highly seasonal monsoon climate prevailed nearer to the coastal regions. Although the climate was more moderate farther from the equator, it was generally warmer than today with no polar ice caps.
At the late Triassic, however, plate tectonic activity occurred , and a period of seafloor spreading began. The Pangaea splitted into two that created two continents, Laurasia and Gondwana. Meanwhile, on the margins of the continents, shallow seas, which had dwindled in area at the end of the Permian, gradually rose, Logan stated that the waters of continental shelves were colonized for the first time by large marine reptiles and reef-building corals of modern aspect.
