Terry Gates a paleontologist from North Caroline State University reveals the secrets of Dinosaur life, including the secrets behind his fantastic size.

He had spent years researching a skull, until one day he had an enlightenment.

Only from the largest skull that had bumps, horns and crests, it suddenly occurred to him that the ornaments on the head were not just an ornament.

Yet it becomes an idea that has now shaken conventional wisdom about how dinosaurs grew to enormous size. Amazing @tanyaschutte
