Massive Dinosaur Skull Unveiled

The skull of a pachyrhinosaur—a four-legged horned herbivore that could grow up to 7 meters long—was unveiled today at the University of Calgary. Researchers dug up the 70-million-year-old fossil last year in Alberta, Canada, after realizing what looked like a bumpy rock was actually a dinosaur bone. The pachyrhinosaur’s head would have spanned well over 2 meters, about the size of a door and only a bit shorter than the skull of a triceratops. After the specimen has been completely cleaned and studied, it will go on display at the university.
