Physeterula dubusi

Physeterula dubusi is an extinct sperm whale of the family Physeteridae, first named by Van Beneden in 1877 and placed in the genus Physeterula. The Paleobiology Database records it as an extinct, actively mobile marine animal that fed as a piscivore and carnivore, with ten fossil occurrences spanning a long interval from the Aquitanian of the early Miocene to the Late Pleistocene. The genus Physeterula was a prehistoric close relative of the sperm whale that lived in Europe and the United States and is classified as large-bodied. Its members kept functional teeth in the upper jaw, though the tooth enamel had degenerated, and the condylobasal length of the skull is estimated to have exceeded 137 centimetres, similar to Idiorophus, Zygophyseter and Brygmophyseter.
