A curious piece of bone spotted by a University of Pennsylvania professor in southern Montana led to the discovery of a 150-million-year-old dinosaur with a long neck, a whip-like tail and a mysterious extra hole in its skull.
The new find -- a Suuwassea emilieae -- is a sauropod, a classification of plant-eating dinosaurs with long necks and tails, small heads, and four elephant-like legs.
The creature’s most striking feature, described in the current issue of the journal Acta Paleontologica Polonica, is the second hole in its skull, never seen before in a North American dinosaur, said a researcher.
