Kentriodon is an extinct genus of toothed whale related to modern-day dolphins. Fossils have been found in North America, Europe and Japan.[1] Several species have been described.
Description
[edit]
Kentriodon was the most diverse of all the kentriodontids, which are represented by seventeen described genera. These were small to medium-sized odontocetes with largely symmetrical skulls, and thought likely to include ancestors of some modern species.[citation needed] Kentriodon is also the oldest described kentriodontid genus, reported from the Late Oligocene to the Middle Miocene.
Kentriodontines ate small fish and other nectonic organisms; they are thought to have been active echolocators, and might have formed pods. The diversity, morphology and distribution of fossils appear parallel to some modern species.[citation needed]
