Scientists at the University of California, Berkley, are saying that the plates that line the back of dinosaurs such as Stegosaurus and Tuojiangosaurus. are just a display that allows animals to recognize other members of their species. They even go so far as to say that many of the unusual characteristics of many dinosaurs - the horns of the ceratopsians, the helmet-heads of the pachycephalosaurs or the crests of the hadrosaurs or dinosaurs such as Monolophosaurus or Dilophosaurus also likely served little function other than to help the animals recognize members of their own species. The scientists are stating that their studies of dinosaur bone histology is leading them to this conclusion.

There have been a number of other ideas proposed for the purpose of the Stegosaur's plates in the past. Some scientists compared them to the ears of elephants - designed to help cool or warm the animal. Other scientists proposed that perhaps they are for protection or for mating displays.

What do you think was the purpose of the plates of the Stegosaur and similar dinosaurs?
