The fossil was that of a megalosaur's distal femur, which Robert Plot described as "the thigh bone of a man or at least of some other animal." In 1818 a tooth-bearing jaw was discovered in Oxfordshire, England (again), and the animal from which it Discovery and Classificati was supposed to have come was named Megalosaurus in Terrible Lizards Discovered 1824. Iguanodon was described in 1825.

The reason for the confusion is since the nineteent that although the division by pelvic structure is valid, tl resemblance of the ornithischian pelvis to that of There is something modern birds is only superficial. that can confuse pe Birds, as we have n As we have said, the famous carnivorous dinosaurs Dinosaur Rece predatory dinosaurs were from the saurischian order; the largest herbivoro dinosaurs were also from this order.
