Homiphoca is an extinct genus ofearless seals from the Pliocene of South Africa.

Taxonomy

[edit]

The type species ofHomiphoca,H. capensis, was originally described as a species of the dubiousdelphinoidPrionodelphis,P. capensis.^[1] Later analysis in 1980 showed thatP. capensis was a pinniped and not a cetacean, necessitating erection of the new genusHomiphoca.^[2] Cladistic analysis placesHomiphoca as a member of Lobodontini, which includes the crabeater, Weddell, Ross, and leopard seals.^[3]^[4]

Fossils

[edit]

Homiphoca remains are known with certainty only from Langebaanweg, South Africa. Remains from Pliocene deposits in Florida and the Lee Creek Mine, North Carolina, have been referred to the genus, although Berta et al. (2015) questioned this referral based on results of their cladistic analysis ofPliophoca.^[5]
