some details. The squamosal bone, which extends behind the postorbital, is also poorly known in T. longobardicus, and many putative squamosal fossils in the species have been reinterpreted as displaced postorbitals. The quadrate bone, which forms the rear edge of the skull and upper half of the jaw joint, is wide and tall. It has a strong lateral crest and a low pterygoid ramus (a vertical internal plate, articulating with the pterygoid bone in the roof of the mouth). No fossils of T. longobardicus preserve a quadratojugal, a bone which normally lies along the quadrate at the rear lower corner of the skull. Nevertheless, a quadratojugal was likely present in the species, since it occurs in T. hydroides and nearly every other early archosauromorph. The frontals (skull roof bones above the orbits) have been described as “axe-shaped flanges”, projecting broad curved plates above each orbit. They are narrowest at the front, together terminating at a three-lobed contact with the nasals. The frontals connect to each other and their neighboring bones along coarse interdigitating (interlocking) sutures. A small triangular bone, the postfrontal, wedges behind the rear outer corner of each frontal. A pair of larger plate-like bones, the parietals, sit directly behind the frontals on the skull roof. In T. longobardicus, the parietals are fairly broad and flat, with a shallowly concave outer edge. Like the frontals, the paired parietals are seemingly separate bones, unfused to each other in every member of the species. A large hole, the pineal foramen (sometimes called the parietal foramen), lies along the midline of the skull at the front of the parietals. When seen from below, a pair of curved crests along the frontals and parietals mark the edge of the forebrain, as defined by a bulbous central hollow. The eye was supported by more than 10 rectangular ossicles (tiny plate-like bones) connecting into a scleral ring, though a full reconstruction of the ring, with 18 ossicles, is conjectural. Few details of the braincase and palate (bony roof of the mouth) are known for T. longobardicus. The scant available evidence suggests that these regions of the skull are rather unspecialized in this species. The vomers (front components of the palate) were narrow and dotted with at least nine tiny teeth. The succeeding palatine and pterygoid bones were also supplied with rows of teeth: up to six relatively large teeth in the former and at least
