With the exception of some abrasion and erosion of the sternal end on the inferior margin and to a portion of the superior edge, and some very slight damage to the lateral edge of the acromial articular surface, the bone is in a perfect state of preservation. There is marked curvature to both the medial and lateral ends of the shaft. There is very little torsion to the shaft, except at the very proximal end, such that the long axis of the sternal articulation is oriented at 135° to the horizontal plane of the acromial end. Medially the shaft cross-section forms an isosceles triangle with the base superior, while laterally the shaft is more rectangular in section, with the superoinferior dimension being the Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Natural History Museum (London).
