H. sternbergi (Brown & Schlaikjer, 1943) |
Hanssuesia is a genus of pachycephalosaurid dinosaur from the late Cretaceous period. It lived in what is now Alberta and Montana. Like other pachycephalosaurs, Hanssuesia had a thick skull roof. However, Hanssuesia is distinguished from other pachycephalosaurs by having a depressed parietal region, wide frontoparietal dome, broad nasal characteristics, reduced prefontal lobes, and a reduced parietosquamosal shelf.
The type species, Hanssuesia sternbergi was named by Sullivan in 2003, based on material originally named Troodon sternbergi by Barnum Brown and Erich Maren Schlaikjer in 1943. It also briefly went by the name Stegoceras sternbergi, due to a perceived conflict in cladistic analyses (Ryan and Evans, 2005).
