How many types of dinosaurs are found on the Island?
There are about 20 properly established Island dinosaurs. The best known are two species of Iguanodon, large herbivores; two unique carnivores, Neovenator and Eotyrannus; the small bipedal herbivore Hypsilophodon; the armoured Polacanthus and a large brachiosaurid. Unfortunately, all of the many names invented for the other Island dinosaurs are based on a few fragments, often upon a single bone!
