Aivukus is an extinct genus of walrus from the Miocene.

Etymology

The generic name is derived from the Inuit word for walrus, aivuk.

Description

From fossil records it was at least as big as, if not slightly bigger than, the modern walrus, and, like the modern walrus, was probably a molluscivore.
