Cetotheriidae is an extinct family of baleen whales in the suborder Mysticeti.[1] The family existed from the Late Oligocene to the Late Pliocene before going extinct.
Taxonomy
Since its description by Brant in 1872, Cetotheriidae was used as a wastebasket taxon for baleen whales which were not assignable to extant whale families.[2] Starting in the early 2000's a number of studies on the phylogeny has reduced the included genera down to thirteen in two subfamilies.[3]
