Georgiacetus is an extinct genus of ancient whale known from the Eocene period of the United States.Fossils are known from Georgia, Alabama, and Mississippi and protocetid fossils from the right time frame, but not yet confirmed as Georgiacetus, have been found in Texas (Kellogg 1936) and South Carolina (Albright 1996).
The two common whales are the large Basilosaurus, and the smaller (3- to 5-metre) Dorudon. [10] At least two other species are known from rarer remains. The whales possess small hind limbs, that are not seen in modern whales, and a powerful skull with teeth similar to those of carnivorous land mammals. [9]

Species of the infraorder Cetacea A phylogenetic tree showing the relationships among cetacean families. [1]The evolution of cetaceans is thought to have begun in the Indian subcontinent from even-toed ungulates (Artiodactyla) 50 million years ago (mya) and to have proceeded over a period of at least 15 million years.

Fossil shark spines found in Michigan are usually the remains of ctenacanths and cladodonts. Bradyodont shark teeth have also been discovered in Michigan, however, it's also possible that these teeth were shed by animals more closely related to holocephalans than true sharks.
