Dromicosaurus Gracilis
''Dromicosaurus'' is a dubious genus of sauropodomorph dinosaur from the Late Triassic or Early Jurassic of South Africa. Its only species is ''D. gracilis''. ''Dromicosaurus'' was named by Egbert Cornelis Nicolaas van Hoepen in 1920 from a fragmentary skeleton he had discovered in the Elliot Formation in Free State. The name, , alludes to the slender legs compared to related genera such as '' Eucnemesaurus''. ''Dromicosaurus'' has repeatedly been considered as a synonym of a species of ''Massospondylus'', but was considered an indeterminate sauropodomorph in the two most recent reviews. Discovery The only known specimen was discovered by the palaeontologist Egbert Cornelis Nicolaas van Hoepen at Noupoortsnek, close to the road from Bethlehem to Clarens. At the time of discovery, weathering had already freed most of the two (the front bones of the pelvis) from the surrounding rock. During the excavation, the shaft of the (shin bone) scattered into pieces, but van Hoepen w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Late Triassic
The Late Triassic is the third and final epoch (geology), epoch of the Triassic geologic time scale, Period in the geologic time scale, spanning the time between annum, Ma and Ma (million years ago). It is preceded by the Middle Triassic Epoch and followed by the Early Jurassic Epoch. The corresponding series (stratigraphy), series of rock beds is known as the Upper Triassic. The Late Triassic is divided into the Carnian, Norian and Rhaetian Geologic time scale, ages. Many of the first dinosaurs evolved during the Late Triassic, including ''Plateosaurus'', ''Coelophysis'', ''Herrerasaurus'', and ''Eoraptor''. The Triassic–Jurassic extinction event began during this epoch and is one of the five major mass extinction events of the Earth. Etymology The Triassic was named in 1834 by Friedrich August von Namoh, Friedrich von Alberti, after a succession of three distinct rock layers (Greek meaning 'triad') that are widespread in southern Germany: the lower Buntsandstein (colourful ...

Thecodontosaurus Skirtopodus
''Hortalotarsus'' is a Nomen dubium, dubious genus of sauropodomorph dinosaur from the Early Jurassic of southern Africa. The only species is ''H. skirtopodus''. ''Hortalotarsus'' was species description, described by Harry Seeley in 1894 based on parts of a hind limb discovered in the Clarens Formation near Makhanda, South Africa. Originally, these fossils were part of the larger part of a skeleton, locally known as the , that had been destroyed using gunpowder in an attempt to remove the bones from the encasing slate. In 1906, Robert Broom assigned a second specimen to the species but later gave it a species of its own, ''Gyposaurus capensis''. In 1906, Friedrich von Huene classified ''Hortalotarsus skirtopodus'' as a species within the European genus ''Thecodontosaurus'', named ''Thecodontosaurus skirtopodus''. Other authors considered ''Hortalotarsus skirtopodus'' as a valid species within the family Anchisauridae, though Michael Cooper Synonym (taxonomy), synonymised it with ...
