expands upwards, though these changes are not as abrupt as in other loricatans. Above the glenoid (shoulder socket) is a prominent roughened area for the triceps muscle. The lower front portion of the scapula has a large acromion, which is unusually hook-shaped in the type specimen of P. chiniquensis due to an oval notch on its upper edge. A low notch is also present at the front edge of the scapula-coracoid suture in most Prestosuchus specimens. This notch has not been reported in any other loricatan and some have considered it an autapomorphy (unique distinguishing feature) of Prestosuchus. The coracoid is low, about twice as long as it is high. Its rear edge has a large contribution to the glenoid, which is preceded by a coracoid foramen and then a horizontal ridge. The horizontal ridge may be an autapomorphy of P. chiniquensis, yet it has also been reported in Procerosuchus and Batrachotomus. The rod-like clavicles have a tall vertical portion which connects to the front of the scapula and a shorter horizontal portion at their base which connects to the tie-shaped interclavicle. The humerus is thick and about two-thirds to three-fourths the length of the femur. It is flattened and very wide near the shoulder, as well as somewhat expanded near the elbow. Bony joints (such as the two distal condyles) and muscle scars (such as the deltopectoral crest) are well-developed. The ulna and radius are thinner but no less strongly developed, with the former having a large olecranon process and the latter having a conical medial process. The hand is a mostly unknown anatomical area in Prestosuchus; only a single metacarpal has been discovered and it is widest towards the wrist. The forelimbs as a whole are similar in structure (though not necessarily proportions) to those of other loricatans like Postosuchus. Hip and hindlimbs Several autapomorphies of Prestosuchus relate to the pelvis (hip). These traits are present in P. chiniquensis and P. nyassicus (Stagonosuchus), but notably absent in "P." loricatus, which is likely a different genus. The ilium has a deep bony acetabulum roofed by a horizontal supraacetabular crest. Unlike other loricatans, there is no vertical crest above the acetabular region. The postacetabular portion of the ilium has a distinctively concave upper edge and is markedly longer than the preacetabular portion. The pubis is straight, with a small contribution to the acetabulum above the obturator foramen. The tip of
