Desmatophocidae is an

pinnipeds closely related to the eared seals and walruses.[1] These animals were the first group of large-bodied pinnipeds to evolve, first appearing in the Early Miocene, with no direct modern descendants.[2] Desmatophocids have only been found to live in the North Pacific, with fossils being found in Baja California, California, Oregon, Washington, and Japan.[3]

The group is generally known for having large orbits, bulbous cheek teeth, and forelimbs similar to extant eared seals.[2]
