... according to research done by scientists at Montana's Museum of the Rockies, the familiar triceratops is really just the juvenile form of the more-elaborately be-frilled and be-horned torosaurus.How to put this gently? Almost all of you rely on the public to pay your salaries. The "Big 3" dinosaurs are (were?) Brontosaurus, Tricerators, and T. Rex. One's gone, and one's on the Endangered Species List. Keep this up, and your paycheck will join them.This extreme shape-shifting was possible because the bone tissue in the frill and horns stayed immature, spongy and riddled with blood vessels, never fully hardening into solid bone as happens in most animals during early adulthood. The only modern animal known to do anything similar is the cassowary, descended from the dinosaurs, which develops a large spongy crest when its skull is about 80 per cent fully grown.
