The Carnegie Museum of Natural History is expansive — a person could spend hours walking the different exhibitions. But what's on display is only a small portion of what's in the museum's possession.

The bones of a new species of meat-eating dinosaur have been discovered in the Patagonia region of Argentina, with the help of a local paleontologist.

Scientists believe the carnivorous Tratayenia rosalesi was about 30 feet long, with serrated teeth like a steak knife and hollow bones. It lived about 85 million years ago, during the Cretaceous period -- the last segment of the age of dinosaurs.
