The genus Kentriodon is the most diverse of all kentriodontids, which include three named species and five undescribed species. Kentriodontidae were small to medium-sized odontocetes (toothed cetaceans) with largely symmetrical skulls, and thought likely to include ancestors of some modern species. Kentriodon is the oldest described kentriodontid genus, reported from the Late Oligocene to the Middle Miocene. were found fossils in Argentina, Peru, Portugal, France, Italy, Belgium, Japan, Ukraine, Moldova, Russia, Romania, Turkey, Austria, Switzerland, Mexico and New Zealand. But also the USA, in California, Florida, New Jersey, Maryland, Pennsylvania, Virginia
Kentriodontines ate small fish and other nectonic organisms; they are thought to have been active echolocators, and might have formed pods. Diversity, morphology and distribution of fossils appear parallel to some modern species.
