Albertochampsa
Albertochampsa is an extinct genus of globidontan alligatoroid (possibly a stem-caiman[1]) from the Late Cretaceous of Alberta. It was named in 1972 by Bruce Erickson, and the type species is A. langstoni.[2] It is known from a skull from the Campanian-age Dinosaur Park Formation, where it was rare; Leidyosuchus is the most commonly found crocodilian at the Park. The skull of Albertochampsa was only about 21 cm long (8.3 in).[3]
