The joint is formed by the sternal end of the clavicle, the clavicular notch of the sternum, and (the superior surface of) the costal cartilage of the first rib. [1] The articular surface of the clavicle is larger than that of the sternum, and is invested with a layer of cartilage, which is considerably thicker than that of the sternum. [1]
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 sternum is a narrow, flat bone, forming the middle portion of the front of the chest. The top of the sternum supports the clavicles (collarbones) and its edges join with the costal cartilages of the first two pairs of ribs. The inner surface of the sternum is also the attachment of the sternopericardial ligaments. [2]
The Eagles tight end made something happen with the team's offense struggling. He made a nice catch on a pass behind him and then took Packers cornerback Carrington Valentine's soul.
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 ...
