tilt of the lower branch of the postorbital, though the magnitude of this tilt is variable between specimens. The jugal is relatively smooth in texture and has extensive sutures with the maxilla, lacrimal, and postorbital, as well as the V-shaped quadratojugal. The squamosal is complex in shape, with a bulbous front branch that is circular in cross-section and a lower branch that infringes on the infratemporal fenestra. The tall and broad quadrate extends from a socket on the rear branch of the squamosal to below the level of the quadratojugal. It also sends forward two large plates of bone which connect with the pterygoid and quadratojugal. The palate was solid, composed of flat and toothless bones. It incorporated long, slender vomers and rectangular palatines which extensively contact the rest of the skull. The pterygoids are standard for loricatans, with a long and plate-like front branch that curves upwards at its inner edge, a thicker laterally branch which curves down, and a two-pronged connection to the quadrate. The pterygoid was also connected to the jugal via a very thick, Y-shaped ectopterygoid. Curved, rod-like hyoid bones were present as well. The left and right lower jaws are relatively long and loosely attached to each other at the symphysis (chin). There are 14 teeth in the dentary, the main tooth-bearing bone of the lower jaw. This bone has a straight or slightly convex lower edge and expands upwards at the chin, unlike Saurosuchus. The splenial, which lies on the inner surface of the dentary, is unusually elongated in Prestosuchus and extends as far forward as the second tooth in the jaw. The rear of the dentary has a shallow incision which defines the front edge of the rounded mandibular fenestra. The lower edge of the mandibular fenestra is mainly bound by the angular, while the surangular forms its upper border. Bones at the rear of the lower jaw have proportions and structures similar to other loricatans. Such structures include a shelf at the rear of the surangular and a thick articular bone which has a tall retroarticular process with an inner prong pierced by a chorda tympani foramen. Vertebrae Cervical (neck) vertebrae are notably tall and their sides are excavated by large ventral depressions, which generates a keel on their lower edge. Many laminae (bony buttresses) are developed on the centrum (main spool-shaped portion of the vertebra). Most of these connect the diapophysis
