5.66 Hadrosaur Coracoid Bone (Judith River)

The coracoid is a crucial shoulder bone found in dinosaurs, birds, and many reptiles. The coracoid paired up directly with the scapula (the shoulder blade) to create the shoulder joint (the glenoid cavity), which held the dinosaur's front arm bone in place.

Hadrosaurs, or duck-billed dinosaurs, were a diverse group of large, herbivorous ornithischian dinosaurs that thrived during the Late Cretaceous Period, known for their broad, duck-like beaks and complex, tooth-battery chewing mechanisms. Often living in herds, they were dominant herbivores across North America, Asia, and Europe, ranging from 30 to over 50 feet in length
