Allodesmus was a large seal-like pinniped that lived in the north Pacific Ocean region during the middle and late Miocene 15 to 10 million years ago (mya). At least three species of Allodesmus are known from California and one from Japan during this time period. A New Fossil Pinniped (Desmatophoca Oregonensis) from the Miocene of the Oregon Coast [Thomas Condon] on *FREE* shipping on qualifying offers. This is a reproduction of a book published before This book may have . The fur seals and sea lions (eared seals), the Otariidae, are diagnosed by single rooted P 3 and P 4, single rooted P 2 and P 4, pronator teres insertion positioned on the proximal 40% of the radius (forearm bone), and secondary shelf of the sustentaculum of the calcaneum (heel bone) developed as a wide shelf (Churchill et al., ; Fig. 5).Although otariids are often divided . A nearly complete pinniped skeleton from the middle Miocene Okoppezawa Formation (ca – Ma), Hokkaido, northern Japan, is described as the holotype of Allodesmus uraiporensis sp. nov.

This is a large and spectacular fossil canine fang with full root still embedded in the jaw of a large Miocene Era pinniped "sea lion" of the species Allodesmus kelloggi. The specimen comes from the famous Shark Tooth Hill deposits in California. The fang has colorful, speckled enamel of blue, gray, black and gold with a whitish gray root. Allodesmus, known by several complete skeletons, retains several features consistent with forelimb propulsion but also displays adaptations for hindlimb swimming (Berta and Adam, ).

Abstract Three new species of the pinnipedimorph Enaliarctos* are described from the marine late Oligocene and early Miocene (Arikareean and Hemingfordian or early Barstovian correlatives) of coastal Oregon. Enaliarctos tedfordi, new species, is based on a partial cranium from the late Oligocene Yaquina Formation.
