About Anserimimus
What it was like
Anserimimus was an ornithomimid, a lightly built, toothless theropod shaped a bit like an ostrich. It was about 3.5 meters (11 feet) long. Its arms were strong for its group, with long, flat claws, which may have helped it dig or pull down branches.
Its world
It lived in the Late Cretaceous, in what is now Mongolia. The Nemegt Formation it comes from was a land of rivers and forests shared with Tarbosaurus, Therizinosaurus, Deinocheirus and the larger ornithomimid Gallimimus.
How it was found
Barsbold named Anserimimus in 1988, from one partial skeleton without a skull.
