vertebrae; 14 dorsal (trunk) vertebrae; three sacral (hip) vertebrae; and ca. 50 caudal (tail) vertebrae. In contrast to the later sauropods, the sides of the dorsal vertebrae did not show deep cavities caused by air sacs invading the bone (). The scapula (shoulder blade) was hourglass-shaped. In the holotype specimen, the scapula and coracoid were unfused, probably connected only via cartilage; this might indicate that the individual was not yet fully mature. The holotype specimen includes the sternum (breastbone) and the (collarbone), which are rarely found with dinosaur skeletons. The clavicula is a rod-like bone that articulates with the lower end of the scapula in an immobile joint. It has been controversial if the left and right clavicles of sauropodomorphs were attached to each other at their ends, thus connecting the left and right shoulder girdles, or if they were pressed against their scapulae along their lengths. The orientation of the clavicle in Sarahsaurus confirms that the former was the case; the ends of both clavicles would probably have been connected to each other by a ligament, though they were not fused. In side view, the scapula was tilted between 45° and 65° relative to the horizontal. This would have allowed the left and right coracoids to almost touch each other at the body midline, while the left and right sterna, which were attached to each other at the midline, would have been located directly behind the coracoids. The humerus (upper arm bone) was more than half the length of the femur (upper thigh bone), and had a large crest on its front side for muscle attachment, the , which extended for half the length of the bone and had an S-shaped edge. In the hand, the (claw bone) of the first finger was the largest. In the hip, the ilium had two downwards-facing bony projections, the ischial and pubic peduncle, which connected to the two lower hip bones, the ischium and the pubis, respectively, as in other dinosaurs. In Sarahsaurus, the ischial peduncle was only half the length of the pubic peduncle. The (hip joint) was formed by all three hip bones, as in other dinosaurs, though in Sarahsaurus the ischium contributed less than half as much as the pubis. The pubis was unique in having two separate openings, the and the pubic foramen; the latter was lacking in most other archosaurs. The femur was straight and elliptical in
