The Permian-Triassic Extinction Event

Bipedal herbivorous basal sauropodomorph Thriving during the Rhaetian age of the Triassic Socket-tooth lizard filling fissures In the chalkstone quarries of Clifton Robust morph in the population Indicating secondary species unlikely Sexual dimorphism or autapomorphies Small size due to insular dwarfism Roots of its teeth not fused with the jaw bone But positioned in separate receptacles Long basipterygoid process on the skull Medium-sized serrated leaf-shaped teeth Short dentary in relation to the lower jaw Ilium subquadrate instead of rounded Hands long, narrow, with extended claws Its tail much longer than neck and body Exact cladistic analyses not decisive Placed in its own Thecodontosauridae Ancestral to Massospondylus Preceding the prosauropod-sauropod split Misassigned species as separate genera Carnivorous phytosaurians and Agrosaurus Scelidosauridae, Anchisauridae or synonyms Thecodontosaurus antiquus the valid species One of the first saurian remains discovered And one of the oldest that existed Once labeled a member of the Squamata Now the very epitome of Dinosauria

Ground dwelling coelophysid theropod, small sized Its name given by Fraas, before elegant jaws The tibia longer than the femur, habits cursorial Large clawed hands, stiff tail, good runner Discovered in the quarry of the Stubensandstein In white sandstone and blue marl sediments The fossils of its ilk were mostly found the same way Haphazard bone position, angular asymmetric limbs Its neck bent unnaturally backwards, grotesque During its last spasms of agony, before death
