The branch of the jugal towards the postorbital is notched. Contact between the postorbital and the excludes the flattened and wide from the supratemporal fenestra. The posterior part of the bone articulates with the postorbital bone and the parietal bone. Megabats have large orbits, which are bordered by well-developed postorbital processes posteriorly. The postorbital in side view is excluded from the supratemporal fenestra. It is characterized by features of the skull, namely of the quadrate and postorbital bones. The lacrimal and postorbital bones around the eye are textured with bumpy projections. The anterior part of the bone articulates with the frontal bone and the postorbital bone. With only a postorbital bar, lemurs have been unable to develop a fovea. The lower branch of the postorbital bone is transversely wide. Heesy shows that the postorbital bar stiffens the lateral orbit. With normal length of postorbital and orbital regions. The postorbital, or brow, horns are 228 (left) and 246 (right) millimetres long. A triangular postorbital horn was present. It is flattened and lacks a postorbital process.
