Pacificotaria is an extinct genus of basal pinnipediform that lived in Oregon during the early to middle Miocene epoch.[1] The only species of this genus is Pacificotaria hadromma making it a monotypic genus.[2]
It is a possible junior synonym of Pteronarctos. However, it is distinguished from its protruding orbits that is positioned further anteriorly on the cranium, its larger bony nares, a robust rostrum, a vaulted palate, and straighter upper cheek tooth rows.[1]
