    The discovery of a dinosaur skeleton complete with the heart region preserved in a fossiil has enabled scientists to make a startling discovery when comparing its CT scan to that of an alligator. Fascinating clip from the BBC natural history programme Walking with Dinosaurs: The Ballad of Big Al.

    Awww was that baby croc making that noise? :3 And daym dinosaurs, even the herbivores had to evolve warm-bloodedness cuz the predators, lik the theropods eventually evolved fast metabolism cuz the prey was slow. Dinosaurs occupied the same ecological niche as mammals. Willow's species was similar to a deer, a herbivore who was warm-blooded so it cuz run fast from predators.
