恐竜説明:
Alxasaurus is often described as the most complete theropod so far found in Asia. It is a rather strange looking creature which, in some ways, resembles an early prosauropod. It is not a sauropod, though. Most of its characteristics suggest that it was a very primitive therizinosaur. The therizinosaurs were a group of medium to large theropod dinosaurs that had small heads, relatively long arms and thin, moderately curved claws on each hand. In primitive forms the claws were about 15 cm long but later therizinosaurs had flattened claws almost 1 m in length.

Alxasaurus had a relatively short tail and a long neck, and was very robustly built at the shoulders. It had more than 40 teeth in the lower jaw. While feeding, the animal may have leaned backwards on its hind legs and tail, reaching upwards to grasp leaves. When down on all four limbs, it may have dug into the ground in search of insects or succulent roots.
