The carpals (wrist of the arm- the thoracic limb) and tarsals (ankle or hock of the leg- the pelvic limb) are made of several smaller bones that lie just proximal to the metacarpals and metatarsals (also seen here, and known as the cannon bones). These bones came from a cow. The accessory sesamoid bones are also seen here.
