In general discussions about the head of an animal. the upper portion is referred to as the “cranium”. while the lower part consists of the mandible. In lizards the foremost bone of the mandible is dentary; it is at the foremost point of the dentary bone that the two halves of mandibles are firmly united ( the symphysis). The mandible articulates with the cranium at the quadrate bone, located near the rear of the cranium. The coronium bone juts up behind the dentary bone and fits into a socket formed by the pterygoid bones of the cranium. The distance from the tip of the snout to the coronoid intersection determines the gape of the lizard.
