Another such fossa is present between the two parietals themselves. As for the underlying parietals themselves, they are slightly concave. The head is black, the black extending to the posterior border of the parietals. The frontal touches the parietals, supraoculars, prefrontals and preoculars. The walls of the frontal, occipital, parietals, and temporals, were very thick. The pineal foramen is large, oval in shape, and slightly sunken into the parietals. In tyrannosaurines, the sagittal crest on the parietals continues forward onto the frontals. This indicates that the parietals are perpendicular to the transmitting beam. The parietals of both species lacked rearward projections and nuchal fossae. The strong sagittal crest on the parietals of "Tarjadia" is not seen in any phytosaur. The parietals of "Kimmerosaurus" do not form a sagittal crest. The parietals have a notch on the front midline. Like in aardvarks, the parietals are relatively large. The parietals are flat, with a straight facial profile. The frontal bones are fused into one large bone, as are the parietals.
