The teeth of Livyatan were among the biggest of any animal at over 31 cm (12 in) in length. [1] Unlike the modern sperm whale, Livyatan had functional teeth in both jaws. The wearing on the teeth indicates that the teeth sheared past each other while biting down, meaning it could bite off large portions of flesh from its prey.
Unlike the modern sperm whale which only has teeth on the bottom jaw, Scaldicetus had teeth in both jaws. The lectotype for S. caretti had at least 45 teeth in total in its mouth in life. Like other macroraptorial sperm whales but unlike the modern sperm whale, the teeth were covered in a thick enamel coating, about 1.2–1.3 mm (0.047–0.051 ...

Like in other raptorials, and unlike in the modern sperm whale, Zygophyseter had tooth enamel. [8] [9] [10] Like in Acrophyseter, the mandibular foramen takes up about 40% of the lower jawbone. The teeth of the upper jaw form an angle of nearly 120 degrees between the crown and the root, which is possibly a characteristic shared by all ...
Albicetus, unlike the modern sperm whale (Physeter macrocephalus), possessed functional and enamel-coated teeth in both jaws. This suggests that it is related to the group of macroraptorial sperm whales which includes Acrophyseter, Brygmophyseter, Livyatan, and Zygophyseter.
