Aivukus cedrosensis

Mammals

Aivukus cedrosensis is an extinct walrus of the Miocene. The genus name comes from the Inuit word for walrus, aivuk. From the fossil record it was at least as big as the modern walrus, and perhaps slightly bigger, and like the modern walrus it was probably a molluscivore, an animal that eats shellfish. Repenning and Tedford named the species in 1977, and the Paleobiology Database records it from Baja California and Baja California Sur in Mexico, in rocks of the Messinian stage, about 7.2 to 5.3 million years ago. Aivukus belongs to the subfamily Odobeninae, the lineage that also includes the living walrus.
