Osteology of the thoracic limb of the African elephant (Loxodonta africana).
The forelimb bones of 8 elephants (7 adults, 1 juvenile) were studied. In addition, the bones of the digits were dissected and studied in situ in a mature specimen. The scapula, humerus and bones of the antebrachium (particularly the ulna) are massive in comparison to the short, relatively small bones of the manus. There are 8 carpal bones, 5 metacarpal bones and 5 digits. Digits 2-4 consist of 3 phalanges each. The 5th digit consists of 2 phalanges, while the 1st is represented by a single phalanx which is tusk-like and pointed. The distal phalanges of digits 2-4 are very small and do not articulate with the middle phalanges. The proximal sesamoids are well developed and are present on the palmar aspect of all 5 metacarpophalangeal joints. All the bones are illustrated from at least 2 aspects.
