Anzu had feathers on its arms and tail, making it look like a big flightless bird.1

Its forelimbs ended in large, sharp claws, unlike modern birds.1

Two of the Anzu skeletons show injuries: one had a broken and healed rib, and another had an arthritic toe bone.1

Anzu lived at the same time as Tyrannosaurus rex and Triceratops.1

The fossils were found in the Hell Creek Formation, which is famous for many dinosaur fossils.1

Anzu belongs to a group called oviraptorosaurs, which are closely related to birds.1
