The humerus is flattened from front to back in a striking manner, so that, seen from the side, it looks most slender; while in reality it is a very broad bone, nearly straight, and with marked rugosities for the attachment of the muscles. We found but one specimen of the humerus, an isolated bone a little smaller than that described by Gaudry.
| Specimen 3218 | Gaudry’s Specimen | |
|---|---|---|
| Humerus, total length | 470 mm. | 500 mm. |
| Humerus, width at proximal end | 232 mm. | 232 mm. |
| Humerus, width at middle of shaft | 165 mm. | 170 mm. |
| Humerus, antero-posterior diam. of shaft | 61 mm. | |
| Humerus, width across epicondyles | 230 mm. | 240 mm. |
We found neither the radius nor the ulna, but Gaudry figures both, giving the following measurements.
| Radius, length | 245 mm. |
| Radius, proximal diam. | 127 mm. |
| Ulna, length (calculated) | 280 mm. |
| Ulna, width of olecranon | 140 mm. |
