Both otariids and odobenids are known from the North Pacific, diverging approximately 19 Ma, with phocids originating in the North Atlantic or Paratethys region 19–14 Ma. Many of these putative reversals may nowbe reinterpreted, in light of the present analysis.

Eared seals (Otariidae) are some of the more common modern pinnipeds on the west coast of North America, and are some of the more common pinniped fossils.

However, as thiswas offered as a pinniped synapomorphy, it should theoreticallya transitional odobenid to lack odobenid synapomorphies, butit would be unconceivable to observe a transitional odobenidlacking several pinniped synapomorphies, considering how fewFrom the results of the present study, we reject many of thesynapomorphies previously used to diagnose Pinnipedia, asmany were founded on hypotheses of sister group relationshipsof Pinnipedia-Ursidae and Phocidae-Odobenidae.

Over the last few Recently, comprehensive morphological datasets including nearly all the well-recognized Mesozoic birds became available, making it feasible for statistically rigorous methods to unveil finer evolutionary patterns during early avian evolution. The oldest definitive pinniped fossils date from approximately 30.6–23 million years ago (Ma) in the North Pacific.

These results provide further support for prolonged freshwater and nearshore phases in the evolution of pinnipeds, prior to the evolution of the extreme level of aquatic adaptation displayed by extant taxa.

However, biochemical studies (Sarich, 1969) challenged this hypothesis suggesting the monophyletic origin, of pinnipeds. (2010). A similar topology was recovered in a parsimony analysis of the same dataset. PinnipedimorphDonoghue, P. C., and Purnell, M. A.
