Kekenodon is an extinct kekenodontid early whale from the Late Oligocene (Chattian) of New Zealand. Measuring 8–9 m (26–30 ft) long, it was a large raptorial whale which hunted marine mammals and penguins. Although at times classified as a basilosaurid, mysticete, or odontocete, recent work suggests that it represents a phylogenetic intermediate form between Basilosauridae and Neoceti.
