A new species of dinosaur discovered in Utah's Grand Staircase was only recently released to the public. Dubbed Gryposaurus Monumentensis (derived from a combination of "hook-beaked lizard" and a tip of the hat to the discovery location) scientists estimate this duck-billed dino could have had as many as 800 teeth in his massive mouth. "While the diet is unknown, given the considerable size of the creature, the massive teeth and jaws are thought to have been used to slice up large amounts of tough, fibrous plant material. The teeth may hold important clues the dinosaur's eating habits. The Utah museum plans to study the composition of the dinosaur teeth, which when compared to other plant-eating dinosaurs from the Kaiparowits Formation, will help researchers decipher differences in diet."
