The period after the Triassic is the Jurassic.
Dinosaurs lived in the Mesozoic Era, which is subdivided into the Triassic, Jurassic, and Cretaceous periods.
There were several groups of dinosaurs that were bipedal. The theropods, which included all carnivorous dinosaurs, are the beast known. But some ornithopods and prosauropods were bipedal as well.
Icthyosaurs and plesiosaurs are both known from Triassic strata. Crinoids were common then, but their history spans more than just the Triassic. Coelophysis appeared in the middle of the Triassic. Phytosaurs and aetosaurs did not survive past the end of the Triassic. Lystrosaurus was a Triassic dicynodont, about the size of a sheep, which has been found on every continent (including Antarctica). Podocarps and other gymnosperms (plants) survived beyond the Triassic period.
The Permian- Triassic extinction event was the greatest extinction on Earth. 95% of all organisms died during this time period, signaling the beginning of the Triassic.
