Kogiopsis
Kogiopsis is a genus of prehistoric, Middle Miocene pygmy sperm whales from the family Kogiidae. Kogiopsis had very long teeth, long, without root. These teeth are found mostly in Florida and South Carolina. In addition to its teeth, Kogiopsis is known primarily from mandibles. The anatomy of the teeth and lower jaws are similar to those of the extinct sperm whale genus, Orycterocetus.
