Pliopedia pacifica is an extinct species of walrus found in what is now Central Valley, California, United States, which lived during the late Miocene. It was an amphibious carnivore.[1]
The holotype specimen (USNM 13627) was collected in 1909 by Robert Anderson, and consists of pieces of both forelimbs.[2]
Known Pliopedia fossils include a humerus, pieces of radius and ulna from both forelimbs, metacarpals, metatarsals, and phalanges. They were discovered in the Paso Robles Formation of San Luis Obispo County, California.
