Gomphotaria pugnax (†Gomphotaria (Barnes & Rashke, 1991))
Order: Carnivora
Suborder: Caniformia
Superfamily: Pinnipedia
Family: Odobenidae
Temporal range: late Miocene of North America (coast of California)
Dimensions: length - 3,5 m, weight - 1400 (?) kg
Gomphotaria pugnax was a species of very large shellfish-eating dusignathine walrus found along the coast of what is now California, during the late Miocene. It had four tusks, with one pair in the lower and upper jaws, and according to wear on the tusks, G. pugnax hammered shellfish open, rather than simply sucking them out of their shells as do modern walruses. In terms of the postcranial skeleton, Gomphotaria and other dusignathine walruses were built more like sea lions than modern walrus. Gomphotaria is a prime example of the extreme diversity that walruses once exhibited.
