"Megalosaurus had large blade-like teeth set in sockets, not adhering to the bone of the jaw as is the case among lizards. Buckland noted this important diagnostic feature, yet he failed to appreciate its importance. For it gave unassailable proof that Megalosaurus was not a gigantic lizard; it was a gigantic reptile with socketed teeth, such as are possessed by the crocodiles, yet it was not a crocodile, either—Buckland was sure of that. In short, Megalosaurus was something new, a reptile the like of which had never before been imagined."
