Hadrosaur Coracoid (Shoulder Bone), Alberta (disposition #001590)

A hadrosaur coracoid (shoulder girdle bone) measuring 11.5 × 6.5 × 5 cm. The coracoid joined with the scapula, or shoulder blade, and contributed to the shoulder socket where the upper arm articulated.

This specimen retains a broad, curved body and a conspicuous coracoid foramen, the natural opening passing through the bone. The opening and surrounding contours provide recognizable anatomical detail, visible from both sides. Stream erosion prior to burial (and/or erosion) has exposed porous bone along portions of the margins and surface, giving the fossil and overall rounded appearance. Certainly unique and rare; even for a hadrosaur (there are only two per animal versus 80 to over 100 combined bones in the vertebral column.

From the Harvey Negrich Collection, its distinctive opening and sculpted form make it an engaging addition to a collection illustrating the different parts of a dinosaur skeleton.
