The skeleton including femora, tibiae, fibulae and incomplete parts of a scapula, humerus, ulna, left and right ischium, vertebrae, ribs, partial armor over the pelvic girdle plus at least 60 detached armor plates and 8 teeth was found in the Late Cretaceous (Upper Campanian) marine Point Loma Formation, near Carlsbad, California.
It is accompanied by the palmar interosseous branch of the median nerve, and overlapped by the contiguous margins of the flexor digitorum profundus and flexor pollicis longus muscles, giving off in this situation muscular branches, and the nutrient arteries of the radius and ulna.
Cubitus is known as Dommel in Flanders and the Netherlands, and his name derives from the French name of the ulna bone.
On the ulna, the trochlear notch is facing more anteriorly, the brachialis insertion is lower, the mid-shaft is larger, and the shaft is more sinusoidal.
X-rays showed that Zeller had broken both of the major bones in his lower left arm (the radius and ulna).
Ursus maritimus tyrannus is an extinct subspecies of bear, known from a single fragmentary ulna found in the gravels of the Thames at Kew Bridge, London.
