Scaldicetus is an extinct genus of highly predatory macroraptorial sperm whale.Although widely used for a number of extinct physeterids with primitive dental morphology consisting of enameled teeth, Scaldicetus as generally recognized appears to be a wastebasket taxon filled with more-or-less unrelated primitive sperm whales.
Engraved on the tooth is a picture of the ship Francis, which artist Fred Myrick served on during the early 1800s. Now, sperm whales are protected under the Marine Mammal Protection Act. So, in ...
Zygophyseter had 28 teeth in the lower jaws and 26 in the upper jaws. [5] The curvature of the teeth increased medially, that is, the teeth in the front of the mouth were straighter than the teeth in the back of the mouth. The back teeth featured more wear than the front teeth.
In comparison, the modern killer whale has teeth around 8 cm (3.1 in) in height and 2.5 cm (0.98 in) in diameter. [3] Like the modern killer whale, the tooth lacks a coat of cementum. However, unlike the modern killer whale, O. paleorca had a circular tooth root as opposed to an oval, and the pulp extended more towards the back than the front. [2]
Frosty, estimated to be almost 5 years old, has only been spotted a handful of times while swimming with its CA216 pod, making sightings of the whale off the California coast “extremely rare ...
Brygmophyseter, known as the biting sperm whale, is an extinct genus of toothed whale in the sperm whale family with one species, B. shigensis. When it was first described in 1994, the species was placed in the genus Scaldicetus based on tooth morphology , but this was later revised in 1995.
A killer whale mom, who shot to fame after she carried her dead calf’s corpse with her for more than two weeks in a harrowing tale of grief, has lost another baby, scientists revealed.. The orca ...
Like the modern killer whale, the snout is broad and relatively short, and the eye socket is relatively small. [3] It had 28 conical teeth in either jaw, unlike the modern killer whale which has, on average, 24. [1] The holotype could have been 4 m (13 ft) long, [3] in contrast to the 7 to 10 m (23 to 33 ft) modern killer whale. [8] The ...
