Spinops sternbergorum

Spinops is an extinct genus of centrosaurine ceratopsian dinosaur from the Late Cretaceous of Alberta, southern Canada. It was a medium-sized ceratopsian, reaching in length and in body mass.

==Discovery and naming== left|thumb|Partial skull in left side, front, and upper views Spinops is known from the holotype NHMUK PV R 16307, a partial parietal bone, preserving most of the midline bar. Referred material include NHMUK PV R 16308, a partial parietal bone, partial dentary and unidentifiable limb fragments, NHMUK PV R 16306, an incomplete skull, preserving only the dorsal portion of the skull, and NHMUK PV R 16309, a partial right squamosal. None of this material was found in articulation, however it was all closely associated in the same bone bed, in the northwestern region ("Steveville Badlands") of the Dinosaur Provincial Park. Fossils of Spinops were first found in 1916, and were housed in the Natural History Museum in London. The material was not described until 2011, when the new species Spinops sternbergorum was erected. The material was probably collected from the upper part of the Oldman Formation or the lower part of the Dinosaur Park Formation, dating to the Campanian stage of the Late Cretaceous period.
