the Triceratops dinosaur—you know, the three horned one—was actually a juvenile form of a Torosaurus, the three horned dinosaur you don't know. Apparently, dinosaurs' skulls can shape-shift.
The scientists... believe that the Torosaurus and Triceratops are actually of the same species. According to the them, as a Triceratops aged, its horns and frill became more similar to that of a Torosaurus. Short becomes long, saw-edged becomes smoothed and so on. Having them be the same species would explain why there were never any young Torosaurus fossils discovered.
The duo say there is a clear transition from triceratops into Torosaurus as the animals grow older. For example, the oldest specimens of triceratops show a marked thinning of the bone where Torosaurus has holes, suggesting they are in the process of becoming fenestrated

Torosaurus will now be abolished as a species and specimens reassigned to Triceratops, says Horner.
