An extraordinary crocodile that terrorized the seas some 130 million years ago has been discovered, and scientists are going gaga.

Paleontologist Dr. Federico Fanti and his colleagues recently unearthed a skull and other fossilized bones in southern Tunisia that belong to the prehistoric beast Machimosaurus rex. Their research, which was supported by the National Geographic Society Committee for Research and Exploration, was published in the journal Cretaceous Research on Monday.

"We were very happy to find out that several skeletons of this new species were fossilized in very good condition," Fanti, a researcher at the University of Bologna in Italy, told The Huffington Post.
