Washington, Oct 3: Fossils excavated in Pipestone Creek, Alberta, Canada, have revealed a new dinosaur species 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.
According to Dr. Philip Currie, renowned palaeontologist and Canada Research Chair of Dinosaur Palaeobiology from the University of Alberta who was involved in the excavation, Northwest Alberta was not previously known for dinosaur material.
