Ankylorhiza is the largest known Oligocene toothed whale and is one of the most completely known early members of this group, with characteristics intermediate between basal and derived cetaceans. The taxon would have had powerful jaw musculature and probably fed on large prey by seizing it and puncturing it with its robust teeth.
The toothed whales (also called odontocetes, systematic name Odontoceti) are a clade of cetaceans that includes dolphins, porpoises, and all other whales with teeth, such as beaked whales and the sperm whales. 73 species of toothed whales are described.
