Dunkleosteus was a fish that had armor-like plates that covered its body. It was enormous in size. It was as big as a school bus. The jaws of this fish were also enormous, but instead of teeth it had sharp plates in its jaws. It was a fearsome predator of the ancient seas. It was a lot bigger than a Great White Shark which is an awesome predator now in the Pacific and Atlantic Oceans. Paleontologists believe that Dunkleosteus might of been cannibalistic, meaning it ate its own species.
The Carnegie Museum of Natural History at 4400 Forbes Avenue in Pittsburgh has a fossil skull of Dunkleosteus in their newly renovated Dinosaur Hall. It can be viewed in the exhibit "Dinosaurs in Their Time" with other fossils.
The paleontologists at the Carnegie Museum have developed a model replica of Dunkleosteus. It was developed from partial fossil skeletons of Dunkleosteus.
