Peripolocetus is a genus of balaenid baleen whale from the middle Miocene of Kern County, California.[1]
Classification
Like other non-balaenopteroid thalassotheres, Peripolocetus was classified as a cetotheriid in the past. When named by American zoologist Remington Kellogg in 1931, it was assigned to Cetotheriidae,[2] an opinion followed by subsequent authors.[3][4][5] However, it was assigned to Mysticeti incertae sedis by one source,[1] and a cladistic analysis of Herpetocetus morrowi recovered Peripolocetus as a member of Balaenoidea.[6] The assignment of Peripolocetus to Balaenoidea was further reinforced by a new specimen from the type locality at Sharktooth Hill Bonebed.[7]
