Physeterula was a prehistoric close relative of the sperm whale that lived in Europe and the United States during the Late Miocene-Late Pliocene. This species is classified as a large-bodied species.
Description Physeterula retained functional maxillary teeth, although its tooth enamel had degenerated. Condylobasal length is estimated to have exceeded 137.5 cm. Physeterula was similar in size to Idiorophus, Zygophyseter, and Brygmophyseter.
