Triassic vertebrates during this time. A specialized subgroup of archosaurs, called dinosaurs, first appeared in the Late Triassic but did not become dominant until the succeeding Jurassic Period. The first true mammals, themselves a specialized subgroup of therapsids, also evolved during this period, as well as the first flying vertebrates, the pterosaurs, who, like the dinosaurs, were a specialized subgroup of archosaurs. The vast supercontinent of Pangaea existed until the mid-Triassic, after which it began to gradually rift into two separate landmasses, Laurasia to the north and Gondwana to the south. The global climate during the Triassic was mostly hot and
Mandla Plant Fossils National Park some work on the plant fossils of Mandla, though the study is yet in a preliminary stage. In Ghuguwa and Umaria the standing, petrified trunks of trees have been identified as Gymnosperms and Angiosperms- Monocotyledons and palms. There are certain Bryophytes also. There is some question about whether the fossils are from the late Jurassic or the early and mid Cretaceous age. This is because when the breakup of the single land mass, Pangaea occurred, it was split by the continental drift into Laurasia and Gondwana somewhere between the Jurassic and Cretaceous ages. India formed a part of Gondwana. Depending
