Thrinaxodon, cynodont (therapsid) Compsognathus populator skull rivaling it inThrinaxodon (pronounced thrin AX ah DON) was a cat sized cynodont, an ancestor of the mammals, but not a mammal itself. Thrinaxodon was not a dinosaur. This therapsid lived during the late Triassic period, roughly 240 million years ago. Small holes in the snout bones suggest that it may have had whiskers, a mammalian characteristic. Its teeth were also similar to those of mammals. The skull was about 1. 5 inches long. Fossils have been found in South
