Skeletal diagram of Veterupristisaurus milneri including all known remains. The middle vertebrae is the holotype (MB R 1938), the pair on the right are the paratypes (MB R 2166), and the far left caudal is the questionably referred vertebra (MB R 1940).
Selected unenlagiid traits: (A) maxilla and dentary of Austroraptor cabazai showing the rostral process of the maxilla, the anteroposteriorly elongated postantral wall, and the sub-parallel dorsal and ventral margins of the dentary. af, antorbital fenestra; mxf, maxillary fenestra; pan, postantral wall.

Achelousaurus horneri skull, collected in Glacier County, Montana, at the Museum of the Rockies in Bozeman, Montana. The Ceratopsidae are those dinosaurs with head frills. There are three large subgroups of Ceratopsidae: Centrosaurinae, Ceratopsinae, and Chasmosaurinae. The Triceratopsini are a "tribe" of the Chasmosaurinae -- a genus so vast that it gets the special name "tribe". The Pachyrhinosaurini are a "tribe" within the Centrosaurinae. Achelousaurus is a genus within the Pachyrhinosaurini. So far, only three skulls and some limited skeletal remains have been collected anywhere in the world -- and all of them in Montana. Their bony frills are quite similar to the Styracosaurus albertensis, although their other skull features (such as big bony bosses on the nose and behind the eyes) are not.
