Whale (Cetacean) Vertebra. From North Carolina, U.S.A. These are found along with Megalodon and Mako teeth in the same locations and make a good companion fossil. In life the Megalodon would have preyed on Whales, and this is evidence in the rib fossils that are found with shark tooth bite marks. Artwork by Nobu Tamura.
Whales are a widely distributed and diverse group of fully aquatic placentalmarine mammals. They are an informal grouping within the infra-order Cetacea, usually excluding dolphins and porpoises. Whales, dolphins and porpoises belong to the order Cetartiodactyla with even-toed ungulates and their closest living relatives are the hippopotamuses, having diverged about 40 million years ago. The two parvorders of whales, baleen whales (Mysticeti) and toothed whales (Odontoceti), are thought to have split apart around 34 million years ago.
Whale ear bone fossils from South Carolina Miocene in age (around 15 Million years old). Whales use these to hear underwater sounds, and some say they can hear for thousands and thousands of miles. Sound travels at around 4 times faster in water than it does on land. There are found in South Carolina, along with Megalodon and Mako sharks, as well as other marine species.
Kogiopsis is a genus of prehistoric, Middle Miocene pygmy sperm whales from the family Kogiidae. Referred to as Kogiopsis floridana in some texts.
