The clavicles fused in some theropod dinosaurs to form a furcula, which is the equivalent to a wishbone. [14] In birds, the clavicles and interclavicle have fused to form a single Y-shaped bone, the furcula or "wishbone" which evolved from the clavicles found in coelurosaurian theropods.

The shoulder girdle or pectoral girdle is the set of bones in the appendicular skeleton which connects to the arm on each side. In humans, it consists of the clavicle and scapula; in those species with three bones in the shoulder, it consists of the clavicle, scapula, and coracoid.
The clavicle consists of a medial end, a shaft, and a lateral end. The medial end connects with the manubrium of the sternum and gives attachments to the fibrous capsule of the sternoclavicular joint, articular disc, and interclavicular ligament. The lateral end connects at the acromion of the scapula which is referred to as the ...
Clavicles are infrequently found with dinosaur skeletons, which probably be due to their low preservation potential. [42] [25]: 49 coracoid The coracoid is a paired bone of the pectoral girdle that is attached to the lower end of the scapula. A flat and in dinosaurs typically semicircle- to square shaped element, it is endochondral in origin ...
Shankland was interested in the idea of studying clavicles, or collarbones, from the shipwreck because the bones showcase unique characteristics related to age, development and growth.
The scapula (pl.: scapulae or scapulas [1]), also known as the shoulder blade, is the bone that connects the humerus (upper arm bone) with the clavicle (collar bone). Like their connected bones, the scapulae are paired, with each scapula on either side of the body being roughly a mirror image of the other.
