Kannemeyeriiform dicynodont from Antarctica

[Halichoeres]

Today in the department of "what can you learn from mere scraps of bone?" An occipital plate (fragment of the back of the skull surrounding the hole where the spinal cord passes), a small piece of maxilla (upper jaw) and a single tusk comprise the most complete dicynodont known from the Antarctic Fremouw Formation. It's enough to identify it as a kannemeyeriiform (related to animals like Placerias and Lisowicia), but not enough to bear a name itself. It's also \evidence that this site is about the same age as a Cynognathus-bearing formation in South Africa, where related dicynodonts are found.
