The Paleontologists, Jack Horner and John Scannella have just shattered everyone's thoughts about the famous Triceratops and Torosaurus that were seen in the late nineteenth century.

They claim that ,no, they are not evolutionary cousins but in fact are the same species with only different versions, for instance Triceratops is just a younger version of Torosaurus.

All this time, the scientists were holding the belief that these two were related species, but in reality the fact was that they were actually seeing the maturation phases of the same animal.

After having studied the fossils of these creatures', the two scientists established that the Triceratops dinosaur and its less-glamorous, holey-headed equivalent, Torosaurus were actually the same species.

The scientists studied and examined dozens of specimens and discovered a chain; a growing chain as the smallest juvenile Triceratops grew up to become the huge Torosaurus.

It was very easy to see the change in the frill of Triceratops with age; the variation was distinctive as the dinosaur grew up to become an adult.

When the scientists studied the bone structure of Triceratops brow horns, they concluded that what everyone had thought of, as grown up dinosaurs, were actually still growing since the Triceratops specimens did not have the required amount of dense, mature bone, which is necessarily there in adults.

This was found in the horns of Torosaurus.
