For over a century, the Triceratops dinosaur has been beloved by both children and adults. Now the existance of the Triceratops is in question based on new studies by John Scannella and Jack Horner. Their study states that Triceratops are actually juveniles of another ceratopsian dinosaur, the Torosaurus, and that their skulls change shape as they age.
The study was written by John Scannella and Jack Horner of the Museum of the Rockies and published in the July 2010 issue of the Journal of Vertebrate Paleontology. The study is a culmination of 10 years of research and examinations of over 30 Triceratops skulls and numerous Torosaurus skulls. The study shows that there is a clear transition from a Triceratops skull into a Torosaurus skull.
