The Almond Formation Ceratopsian is an unnamed genus of chasmosaurine ceratopsian dinosaur that lived in Wyoming and possibly Alberta during the Late Cretaceous.
Description[]
The Almond Formation Ceratopsian is a specimen from Sweetwater county in Wyoming. The specimen, FR 3652 is known from a partial skull, ilium, and assorted bone fragments. The Specimen was discovered during the 1937 joint expedition between the American Museum of Natural History and the Sinclair Oil Company. AMNH 3656 may represent a frill fragment from another individual, but since their is no overlapping material it is impossible to tell if it belongs to this genus, or it represents another new animal. Another individual from the Horseshoe Canyon formation of Alberta has also been referred to this species. Without more extensive frill material it is extremely difficult to name a new species from the specimen. All that is currently known taxonomically from the specimen is that it represents a Chasmosaurine Ceratopsian closely related to Arrhinoceratops and Anchiceratops. An analysis posted in 2021 identified a new taxon, Bisticeratops, that represents a sister taxon to the Almond formation Ceratopsian, whether or not it is the same specimen as the Horseshoe Canyon specimen is unknown.
