[D] Albertaceratops nesmoi [Su] [sG] [T]
Describer
Ryan, 2007
Time
Cretaceous Late, Campanian
Classification
Ornithischia Genasauria Cerapoda Marginocephalia Ceratopia Neoceratopia Ceratopidae Centrosaurinae
Diet
Herbivore
Fossilsite
Milk River badlands, south side of Milk River on the Pinhorn Grazing Reserve, approximately 15 km south of Manyberries, Oldman Formation, Alberta, Canada
Info
Genus - Typespecies - Skull
Etymology: Alberta (name of province where the holotype skull was discovered) ceratops (horned-face, Latinized Greek). A patronym in honor of Cecil Nesmo, a rancher from southern Alberta, whose assistance and hospitality has facilitated the collection of many important paleontological specimens, including the holotype of Albertaceratops n. gen.
Holotype TMP 2001.26.1. An almost complete skull, preserved in a friable, light grey, muddy siltstone.
The unfused, adult-sized nasal horncores of Albertaceratops (broken in the holotype) closely resemble the small, juvenile, unfused, nasal horncores of Pachyrhinosaurus canadensis but they are tenfold larger. The large parietal processes at the caudolateral margins of the parietal differ from those of Pachyrhinosaurus in being shorter but with longer bases, and having highly rugose surficial texture.
Referred specimens come from a bone bed in the lower Judith River Formation near Havre, Montana, along the west side of Kennedy Coulee bordering the Milk River.
