Radius

One of two bones which constitute the forearm. The largest portion of the radius is at the wrist joint where it articulates with the carpal bones of the hand. Above, the radius articulates with the humerus at the elbow joint. Bony injury (fracture) to the radius occurs most commonly at the wrist. A bone found in the forelimb of vertebrates.

Need help identifying these bones

Indeed, that does not look like a bone of your regular four-legged animal, since they usually have elongated radius and ulna, and shortened humerus (and the same applies for the hind legs as well). Unfortunately the palm is missing and without that my expertise is not enough ...
