Aulophyseter is an extinct genus of sperm whales from the Miocene formations of the west and east coasts of North America, as well as the Patagonian region of South America. It is a possible synonym of some fossils assigned to Orycterocetus.[citation needed]

Aulophyseter reached a length of 6 m (20 ft) with an estimated body weight of 1100 kg.[2]
