the 3rd or 4th vertebrae down to the last known caudals in the series. The cervical ribs are long and thin, becoming more robust and tapered as they move down the neck. Some of the cervical ribs from bottom half of the neck have a slight facet on the inside surface at their tips that may have held the tip of the preceding rib, forming a rigid cervical rib series (also suggested for the long necked Tanystropheus) that would stiffen the neck. The trunk ribs are long and curve outwards, indicating Azendohsaurus had a broad and deep barrel-shaped chest. The length and curvature of the ribs decreases down the spine, and the last rib is short, fused completely to the final dorsal vertebra, and points directly outwards to the sides. Only a single set of gastralia is known for Azendohsaurus, and their very delicate build and rarity compared to other bones suggests that it did not have a well developed basket of gastralia under the belly like some other archosauromorphs (e.g. Proterosuchus). Limbs and girdles The forelimbs and shoulders (pectoral girdle) of Azendohsaurus are well developed and robust. The scapula (shoulder blade) is long, about twice as tall as it is wide, matching the length and curvature of the ribs to accommodate the deep chest. The blade is concave on each side with a slightly expanded tip that is pointed at the back. The interclavicle is large and robust, and shares with Trilophosaurus and some rhynchosaurs a long "paddle-like" posterior process that is flattened and expanded towards the tip. It also has a unique forward-pointing process, a feature it shares only with Protorosaurus and some early diapsids (most other archosauromorphs have a notch instead). The coracoids are large and rounded, articulating with the scapula to form the glenoid (shoulder socket). The glenoid faces laterally, typical of sprawling reptiles, however, the scapular portion is directed slightly backwards, which could indicate the humerus was held in a more raised posture. The humerus itself is large and broadly expanded at both ends, leaving a relatively narrow "waisted" mid-shaft, with a very well developed deltopectoral crest. The radius is similarly stocky with slightly expanded ends, while the ulna is greatly expanded at both ends, though to a lesser extent distally. The hips (pelvic girdle) are not as deep as the shoulders, with the three hip bones being roughly equal in size. The ilium is
