Shuvuuia was a small and lightly built animal that was a genus of the Alvarezsaur dinosaurs.

Behaviour And AppearanceEdit

At 60 cm (2 ft) in length it is one of the smallest known dinosaurs. The skull is lightly built with long and slender jaws and minute teeth. Shuvuuia is unique among non-avian theropods in the skull's ability to perform prokinesis, that is,
it could flex its upper jaw independently of its braincase.The hindlimbs of Shuvuuia were long, slender, and short-toed, which may indicate significant running capabilities. The forelimbs, however, were unusually short and powerfully constructed. Although originally Shuvuuia and other alvarezsaurids were thought to have only a single digit on the front limb, newer specimens show the presence of reduced second and third fingers in addition to the massively enlarged thumb known from previous specimens. Like other alverezsaurids, Shuvuuia may have used its forelimbs to open insect nests, and its slender, unusually mobile jaws to probe after such prey.
