Description

Compsodon helmoedi was originally described by Egbert Cornelis Nicolaas van Hoepen in 1934 on the basis of a single specimen from late Permian deposits in the Karoo Basin of South Africa.[1] Two additional specimens from South African museum collections and three new specimens from the Luangwa Basin of Zambia have elucidated new aspects of the morphology of this species and indicate that it occurred in the upper Cistecephalus and lower Daptocephalus assemblage zones. Compsodon can be diagnosed by features of its palate, but also the presence of maxillary postcanines and parietals fused and narrowly exposed between broad postorbitals on the dorsal surface of the skull.[2]

gollark: An interesting consequence of intellectual property and stuff is that since binary data (some of which is copyrighted) is isomorphic to very big numbers, some numbers can't be legally distributed (by everyone).
gollark: Probably a somewhat positive thing in general. But really weird.
gollark: Copyright and intellectual property are just really weird now we have computers.
gollark: Which has created all kinds of exciting problems.
gollark: Also there's a provision on it which bans working around DRM schemes.
