English: A fossil Dunkleosteus terrelli skull on display in the Sant Hall of Oceans in the Smithsonian Museum of Natural History.
Dunkleosteus terrelli was a prehistoric fish that lived about 380 to 360 million years ago. Unlike modern fish, it had heavy bones (not cartilage) in its skull. It was a carnivore, about 33 feet long, and the second-largest predator in the ocean at the time. Dunkleosteus terrelli was first discovered in 1873. At the time, scientists thought it was part of the species Dinichthys, but they have since realized it was a separate species. Dunkleosteus was renamed in 1956. The name honors David Dunkle, a paleontologist at the Cleveland Museum of Natural History. There are several sub-species, but Dunkleosteus terrelli is the largest. It has been found throughout the U.S. (Ohio, Pennsylvania, Tennessee, California, and Texas). This fossil was found in Red Hill, Pennsylvania. |
