Abelisaurus, which joins the distinguished likes of Ankylosaurus, Ichthyosaurus, Mosasaurus, Plesiosaurus, Stegosaurus, and Tyrannosaurus rex in having an entire group of animals named after it, is presently known from only an incomplete skull. But based on what we have learned about other abelisaurs such as Rajasaurus, Majungasaurus, and, of course, Carnotaurus, we have a reasonably good idea of what Abelisaurus looked like: a stocky brute with a boxy head, muscle-bound legs, and itsy-bitsy arms.
