File this one under better late than never. Canadian scientists have identified a new species of dinosaur from fossils that were originally collected in 1958.
Paleontologists have discovered a new species of dinosaur with a softball-sized lump of solid bone on top of its skull, according to a paper published in the April issue of the journal Cretaceous Research.
The fossils revealed a herd of dinosaurs that perished in a catastrophic event 72.5 million years ago. The animals are characterized by a bony frill on the back of the skull ornamented with smaller horns. They also had large bony structures above their nose and eyes which lends them their name: Pachyrhinosaurus (thick-nosed lizard). These structures probably supported horns of keratin.
