<p>Twenty months after announcing their discovery of a new species found in Alaska called the Pachyrhinosaurus perotorum, paleontologists from the Perot Museum of Nature and Science in Dallas have since uncovered a juvenile specimen that came from the same hole in the ground. The scientific paper describing the find – entitled “An immature Pachyrhinosaurus perotorum(Dinosauria: Ceratopsidae) nasal reveals unexpected complexity of craniofacial ontogeny and integument in Pachyrhinosaurus” –  was posted late yesterday on the prestigious science journal.
