A shark, Carcharias morricei, and a sperm whale, Aulephyseter morricei.
Named in honor of Charles Morrice:
A major highlight of the museum excavations was the discovery of an almost fully intact skeleton of the extinct sea lion, Allodesmus. Since articulated remains of marine mammals are extremely rare in the bone-bearing zone, such a complete specimen ranks as one of the most important finds in the history of explorations at Sharktooth Hill.

A shark, Carcharias morricei, and a sperm whale, Aulephyseter morricei.
Named in honor of Charles Morrice:
A major highlight of the museum excavations was the discovery of an almost fully intact skeleton of the extinct sea lion, Allodesmus. Since articulated remains of marine mammals are extremely rare in the bone-bearing zone, such a complete specimen ranks as one of the most important finds in the history of explorations at Sharktooth Hill.
from the Temblor Formation includes 10 types of dolphins and dolphin-like creatures, a porpoise, one sea lion, five kinds of whales, a sea cow, a walrus, a seal and an extinct hippopotamus-like fellow called Desmostylus--a 10-foot-long animal related to the elephant that evidently walked around on the sea floor crushing shellfish with its massive, powerful jaws. Also identified have been four extinct large turtles, a marine crocodile, many kinds of bony fishes, 20 species of birds, and some 27 species of sharks and rays.

In addition to the marine fauna, several skeletal elements from land mammals have also been taken from the fossil beds. These include bones from a sloth, a camel, a horse, a tapir and a mastodon. Such remains are exceedingly rare, though, and are usually considered anomalies in the local Middle Miocene fossil record. Their presence in proved marine-deposited rocks points to preservation in shallow sea waters, since it is unlikely that the carcasses of land animals could have been transported far from the ancient shoreline before they settled to the ocean floor.
