The shape of the posterior portion of the temporal fossa, the posterior development of the lambdoid crest, and the orientation of the squamosal fossa result in different arrangements and function of the temporal muscle in the two taxa.

Finally, the different relationships that the foramen pseudo-ovale has with the surrounding bones suggests different developmental paths of the ventrolateral surface of the skull posteriorly to the supraorbital process of the frontal.
