Titanogomphodon

Titanogomphdon is an extinct genus of diademodontid cynodonts from the Middle Triassic Omingonde Formation of Namibia. It is known from a single partial skull that was described in 1973 from the Omingonde Formation. The type and only species is "Titanogomphodon crassus". At about , the skull of "Titanogomphodon" was significantly larger than that of its closest relative, "Diademodon" (hundreds of skulls of "Diademodon" are known and none exceed in length). Its teeth are similar to those of another group of cynodonts called Traversodontidae, but the similarities are likely the result of convergent evolution. Aside from its larger size, "Titanogomphodon" differs from "Diademodon" in having a bony projection on the postorbital bar behind the eye socket.
Diet.
Like "Diademodon", "Titanogomphodon" was probably herbivorous. It is part of a very diverse fossil assemblage in the Omingonde Formation that includes several other types of cynodonts, including "Diademodon", "Cynognathus", and "Trirachodon", as well as other therapsids such as "Dolichuranus" and "Herpetogale". The Omingonde assemblage was part of a larger continental fauna that ranged across much of Gondwana during the Middle Triassic.
Other finds.
An isolated upper jaw of a diademodontid described from the Fremouw Formation of Antarctica in 1995 may also belong to "Titanogomphodon" based on its large size. However, since the only known fossil of "Titanogomphodon" is a lower jaw, the two specimens cannot be assigned with certainty to the same taxon.
