Anchisaurus is a genus of dinosaurs
Discovery of Anchisaurus Dinosaur.
Today, parts of Anchisaurus Dinosaur skeleton are still missing. Reconstructions typically assume that the tail and neck are like that of other dinosaurs of the same family, prosauropods. Anchisaurus was quite characteristic of this group and so this assumption is probably justified.
Description Of Anchisaurus Dinosaur
On the new hand, paleontologists believe Anchisaurus may also have eaten meat, as it was in the transition between these two ultimately separate groups. The teeth were blunt but with file-like edges, suggesting mostly plant matter was eaten, and the jaw hinge was set in a way not entirely suited for tearing meat. Nevertheless, there is still some debate. The thumb had a huge claw, and the large eyes were not entirely on the side (as would be expected in an animal used to being prey).
As a quadropedal/bipedal crossover, Anchisaurus have flexible front legs. As hands, they could be turned inwards and be used for grasping. It had a simple reversible first finger, similar to a thumb. As feet, the five toes could be located flat against the floor and were strong at the ankle. This unspecialized design is typical of the early dinosaurs.
Classification of Anchisaurus Dinosaur
Anchisaurus is sometimes known as Yaleosaurus, due to Huene (1932). Marsh was initially happy with Hitchcock's name Megadactylus, but this name was already taken. Therefore, he renamed it Amphisaurus in 1882. However, this name was also worried! Therefore, it became Anchisaurus in 1885. The type species is Hitchcock's A. polyzelus. Marsh's A. major ("greater near lizard") is still measured among the Anchisaurs. However, his A. colurus of 1891 is now generally established as a female A. polyzelus, and his A. solus of 1892 is now reclassified as Ammosaurus major. However, Ammosaurus itself may well be a synonym of A. polyzelus. Broom named "Gyposaurus" in 1911, from the bones exposed in South Africa, but Peter Galton officially named it A. capensis in 1971. This genus has since been reclassified again, and is now Massospondylus carinatus. Other specimens are still pending reclassification. This confusion is typical of the first dinosaurs to be exposed, when classification was not considered such a significant process.
