The postfrontal is a paired cranial bone found in many tetrapods. It occupies an area of the skull roof between and behind the orbits (eye sockets), lateral...

bone is situated, on each side, between the frontal bone and the maxilla, and may or may not be in contact with the nasal bone. The postfrontal bone,...

Boids are, however, distinguished from the pythons in that none has postfrontal bones or premaxillary teeth, and that they give birth to live young. When...

lacrimal bones are the only two remaining from the ancestral circumorbital series: the prefrontal, postfrontal, postorbital, jugal, and lacrimal bones. During...

al. (2003) identified a postfrontal bone in front of the postorbital, but CT data from Clack et al. (2019) argued that this bone was actually the postorbital...

autapomorphies (unique features) of the skull is the fact that the postfrontal bones, which typically occupy the upper rear corner of the orbits, are very...

The upper rim of the eye socket consists of a bone bar formed by the prefrontal and the postfrontal bones. The postorbital in side view is excluded from...
