After years of study, scientists have now given a name to a shark that lived over 300 million years ago.

Eastern New Mexico was once surrounded by a seaway that stretched all the way through North America. According to Hodnett and his associates, Hoffman's dragon shark most likely hunted crustaceans, squid, and other sharks in the shallows along the coast.

Many dinosaur bones have been discovered in New Mexico's high desert plateaus, including some species of tyrannosaurus that roamed the land millions of years ago when it was a tropical rain forest.
