Researchers have recently made a discovery about the famous triceratops: it may not be a separate dinosaur species but instead a younger version of a Torosaurus.
Due to their appearance, for many years the triceratops, with a three-horned skull and a shorter frill and the torosaurus, with a much bigger frill and two large holes through it, were believed to be different types of dinosaurs.
Now, in the July 14 edition of the Journal of Vertebrate Paleontology, John Scannella, a Montana State University paleontologist, and Jack Horner, dinosaur curator at the Museum of the Rockies, say a triceratops is actually a younger torosaurus.
