Taxonomy

Oxyacodon was named by Osborn and Earle (1895). Its type is Oxyacodon apiculatus. It was assigned to Periptychidae by Osborn and Earle (1895) and Carroll (1988); and to Conacodontinae by Archibald (1998), Eberle (2003) and Middleton and Dewar (2004).

Fossils have been found dating back to the Puercan stage in New Mexico, Colorado, Utah, Wyoming, Montana, North Dakota and Saskatchewan.

gollark: Yes, nim.
