Taxonomic remark From Berta, 2018: A later diverging lineage more closely allied with pinnipeds than with Enaliarctos is Pteronarctos from the late Miocene (19–15Ma) of coastal Oregon. Pteronarctos is recognized as the earliest pinniped to have evolved the unique maxilla diagnostic of modern pinnipeds. ... Closely related to Pteronarctos from the same stratigraphic unit is Pacificotaria. Ecologically, the earliest pinnipedimorphs were coastal dwellers that evolved a pierce feeding strategy and likely fed on fish and other aquatic prey (Adam and Berta, 2002; Churchill and Clementz, 2016).
