Bizarre DinosaursDVD - 2010
Join world-renowned paleontologists and travel the globe to unearth some of the lesser-known but most surprising members of the dinosaur family, such as Mamenchisaurus, whose neck alone was longer than the rest of its body; Chasmosaurus, adorned with a fashionable crown of frilly spikes; Spinosaurus, with massive extensions from its vertebrae that could have supported a sail or hump; and Parasaurolophus, whose tube-like head crest look odd to us, but was a mating magnet. Find out why these animals adopted such strange appendages and what was their purpose.
