Datos curiosos
Alxasaurus is one of the earliest known therizinosauroids, but it already had the long neck, short tail, and big claws of later relatives.1
Its hand claws were long, curved, and sharp, but it used them for gathering plants, not for hunting.1
Alxasaurus had a semilunate carpal bone in its wrist, a feature shared with birds and other maniraptoran theropods.1
Five specimens of Alxasaurus were found together in 1988 during the China-Canada Dinosaur Project.1
Its fossils come from the Bayin-Gobi Formation, which is about 113 to 100 million years old (Early Cretaceous).12
The discovery of Alxasaurus helped prove that therizinosaurs were actually weird theropod dinosaurs, not late-surviving sauropodomorphs.1
