| Description | Lophocetus ("crested whale") is an extinct genus of dolphin belonging to the clade Delphinida that is known fromm late Miocene (Tortonian) marine deposits in California and Maryland. Although usually placed in Kentriodontidae, recent studies have found it only distantly related to Kentriodon.
