Mammalodontidae

Mammalodontidae is a family of extinct whales known from the Oligocene of Australia and New Zealand. There are currently two genera in this family: Janjucetus and Mammalodon. After a new cladistic analysis by Fitzgerald (2010), Janjucetus was transferred into Mammalodontidae, thereby making Janjucetidae a junior synonym of Mammalodontidae. Analysing the jaw morphology of the toothed mysticetes, found eight mandibular characters unique to the members of Mammalodontidae:
