The infraorder Pinnipedia consists of 3 families containing 34 extant species belonging to 22 genera and divided into 48 extant subspecies, as well the extinct Caribbean monk seal and Japanese sea lion species, which are the only pinniped species to go extinct since prehistoric times. This does not include hybrid species or extinct prehistoric ...
In the case of pinnipeds (in particular phocid seals) a lot of fossils are fragmentary, yet given names to known or new taxa based on ecomorphotype groupings. Rule, Burin & Park (2024) find that such categorization is not reliably useful for assigning isolated fossils names and consider the majority of extinct phocid seal species to be nomina ...

Enaliarctos [2] is an extinct genus of pinnipedimorph, and may represent the ancestor to all pinnipeds. The five species in the genus Enaliarctos have been recovered from late Oligocene and early Miocene (ca. 28-17 million years ago) strata of California and Oregon. [1]
Puijila darwini is an extinct species of stem-pinniped (seal) which lived during the Miocene about 21 to 24 million years ago. About a metre (3 feet) long, the animal had only minimal physical adaptations for swimming.
Odobenidae is a family of pinnipeds, of which the only extant species is the walrus (Odobenus rosmarus). In the past, however, the group was much more diverse, and includes more than a dozen fossil genera.
Desmatophocidae is an extinct family of pinnipeds closely related to either the eared seals and walruses [1] or to the earless seals. [2] [3] These animals were the first group of large-bodied pinnipeds to evolve, first appearing in the Early Miocene, with no direct modern descendants. [4]
Atopotarus is an extinct genus of pinniped from the middle Miocene known from one specimen (holotype LACM 1376) from Los Angeles County, California.It belongs to the extinct family Desmatophocidae, an early lineage of seal-like pinnipeds from the North Pacific.
