Description
Running Thecodontosaurus antiquus, a basal sauropodomorph from the Late Triassic (Rhaetian) of Southern England. This reptile was described in 1836 from finds from a quarry in present-day Bristol. Then it was classified as squamate, and the name ("lizard with teeth in sockets" in translation) emphasized the differences in the fastening of teeth). It was only in 1870 that Thomas Huxley attributed Thecodontosaurus to dinosaurs (now it is obvious that all dinosaurs had thecodont teeth attachment). Later, many bones were found in the "fissure fillings", some of which were destroyed during the bombing of Bristol. Today, about 245 fragmentary fossils are known, from which it is possible to make up almost an entire skeleton. In 1891, the supposedly Australian material of Thecodontosaurus was separated into the genus Agrosaurus, but it turned out that it was incorrectly labeled. One juvenile specimen was describes as the genus Pantydraco in 2007. Thecodontosaurus was a small long-tailed dinosaur, the largest specimens were 2.5 m in length (and the average length was only 1.2 m). Michael Benton noted in 2000 that there was a robust morph among Thecodontosaurus. This may indicate sexual dimorphism.

Here I tried to convey the scaly integument with vertical hatching. Let's see how this method will manifest itself in future works. The filaments are speculative.
