Hanssuesia is based on a skull dome originally named Troodon sternbergi by Barnum Brown and Erich Maren Schlaikjer in 1943. The specific name honoured Charles Mortram Sternberg who found the dome in 1928 near Steveville in south Alberta.[1] In 1945, it was transferred to Stegoceras by C.M. Sternberg himself, as a Stegoceras sternbergi.[2]
The genus Hanssuesia was first named by Robert M. Sullivan in 2003. It honours paleontologist Hans-Dieter Sues.[3] In the publication also the spelling variant "Hanssuessia" appeared; the same year Sullivan chose for Hanssuesia as the valid name.[4] Its type species is Troodon sternbergi, the combinatio nova is Hanssuesia sternbergi.
Like other pachycephalosaurs, Hanssuesia had a thick skull roof. However, Hanssuesia is distinguished from other pachycephalosaurs by having a depressed parietal region, a frontoparietal dome that is wide in front as well as in the rear, a broad nasal boss on the frontals, reduced but swollen prefrontal lobes, and a reduced parietosquamosal shelf at the dome rear.[3] A 2020 CSVP abstract found Gravitholus and Hanssuesia to be synonymous with Stegoceras.[5]
