Avimimus
portentosus was a birdlike dinosaur
that lived in the delayed Cretaceous in what is now Mongolia.

Avimimus
Portentosus Dinosaur had a extended neck, a short
toothless mouth, and the bones in its wrists were compound
together, much like that of the current day cockatoo. It
had the ability to fold its whole arm next to its body,
much like the wings of a bird. Unlike a bird however, A.
portentosus had a long bony tail and its pelvis resembles
that of extra theropod dinosaurs.
It is probable that A. portentosus had feathers; however,
the deposits in which it was establish are too coarse for
such features to be preserved. Even if it did have fine
hair, it seems unlikely that it would be able to realize
flight, due to its large body.

It was discovered near the fossils of other theropod dinosaurs,
particularly sinosauropteryx and
caudipteryx.
