Skulls of new dinosaur species found in Utah

Scientists have made a rare discover: four skulls of a new species of giant plant-eating dinosaur, one of them completely intact.

Skulls of plant-eating Dinosaurs were so light and fragile that they have hardly been preserved to be discovered by paleontologists. Reaction to the discover, made in Dinosaur National Monument in eastern Utah, was "probably not printable in a newspaper," said Dan Chure, a paleontologist with the monument.

Chure said that everyone was actually dumbfounded and can go your complete career without seeing one of these. .To find multiple heads was just phenomenal.

Abydosaurus, which lived about 100 million years before, is a type of sauropod, the largest kind of dinosaur to walk on land. Like its relative Brachiosaurus, the long-necked Abydosaurus had a massive body with 3-trunk legs but a relatively tiny head, about one-two-hundredth the size of its body mass. The smallest sauropods might weigh as little as 10 tons; the largest as much as 50 or 60 tons.

The skulls that were found out were those of juvenile dinosaurs, which were probably about 25 feet long when they died, Chure said.

The dearth of skulls among Dinosaur Fossils has posed a hurdle in discovering about the creatures' biology and evolution, researchers said.
