Cretaceous Ornithosaurs sometimes differ from birds apparently in admitting the quadrato-jugal bone into the orbit.
In front of the palatine the cartilaginous snout is overlapped by three membrane bones, the jugal, maxilla and premaxillae.
The occurrence of a postfrontal and its union with the jugal behind the orbit, are characteristic reptilian features.
In poisonous snakes the place of the jugal is taken by the zygomatic ligament which connects the quadrate and maxillae.
In the skull (fig. 83) the postorbital processes of the frontal and jugal almost or quite meet.
