Behind either condyle is a depression, the condyloid fossa, which receives the posterior margin of the superior facet of the atlas when the head is bent backward; the floor of this fossa is sometimes perforated by the condyloid canal, through which an emissary vein passes from the transverse sinus.

They receive the blood from the superior petrosal sinuses at the base of the petrous portion of the temporal bone; they communicate with the veins of the pericranium by means of the mastoid and condyloid emissary veins; and they receive some of the inferior cerebral and inferior cerebellar veins, and some veins from the diplo?

The significance of Struthers'ligament, as Darwin and Struthers understood, is that the vestigial organ has no function in humans, but is inherited from a structure, the supra-condyloid foramen, which certainly had a function in other mammals including marsupials and homologous with the foramen in other mammals, and that therefore humans and other mammals had a common ancestor.

Furthermore, although overlapping materials between the genera are limited to their partial skulls, according to Godefroit " et al . " ( 2012 ) " Kundurosaurus " can be differentiated from " Kerberosaurus " on the basis of the rostrocaudally longer and more robust dorsal maxillary process, more robust and more curved downwards nasal, much more robust and proportionally higher quadrate and the strong ridge extends obliquely along the lateral side of the exoccipital condyloid in " Kundurosaurus ".
