Hanssuesia sternbergi
(For Hans Sues and Sternberg)Etymology
Hanssuesia is named in honour of palaeontologist Hans-Dieter Sues.
The
species epithet,
sternbergi, honours discoverer Charles Mortram Sternberg.
Troodon sternbergi (Brown and Schlaikjer, 1943).
Stegoceras sternbergi (Sternberg, 1945).
Gravitholus sternbergi (Sullivan, 2000).
"
Hanssuessia" (Sullivan, 2003).
Discovery
The name-bearing remains of
Hanssuesia were discovered in the Dinosaur Park Formation (Belly River Group), southeast of Steveville, Alberta, Canada, by Charles Mortram Sternberg in 1928.
The
holotype (CMN 8817) is a skull dome that Barnum Brown and Erich Maren Schlaikjer named Troodon sternbergi in 1943.
In 2003, Sullivan referred a plethora of mainly skull domes to
Hanssuesia, including
UCMP 130051 (from the Judith River Formation of Montana), TMP 2000.26.01 (from the Oldman Formation), UALVP-3 (collected by George F Sternberg in the Oldman Formation at Steveville in 1920), MOR 453 and MOR 480 (from the Two Medicine Formation, Glacier County, Montana), CMN 192, CMN 1953, CMN 2379, CMN 8945, CMN 9148, TMP 79.14.853, TMP 87.36.363, CMN 1075, TMP 85.36.240 and UALVP-8502 from who knows where, TMP 89.69.21 and CMN 8944 (that he managed to assign to Pachycephalosauria indet. in the same paper) and TMP 98.93.125 (that he also referred to
Prenocephale brevis).
