Fig. 13 Ribs of individual 3, superior, x fragment has a maximum length of and a maximum width of One edge (either superior or inferior margin) is pre- served on the side concreted to the rock. Three small, non-diagnostic rib fragments were given museum designations (incorporating two fragments, GC 87 117 A & B) and (GC 87 246). In addition, GC 87 208 is the proximal half of a left rib which, because of a strong possibility that it may be non-human, was not given a museum designation. The articular surface of the head of this specimen is unfused and missing. The body below the tubercle is narrow superoinferiorly (7 to 8mm) out to the posterior angle, where the body flares to a superoinferior diameter of ca. 16mm. Just distal of the tubercle, the rib has a mediolateral diameter of and a superoinferior diameter of The rib bears a round articular tubercle (10mm in diameter) but no non-articular tubercle. A shallow subcostal groove is present. There is no trace of the iliocostalis line at the posterior angle. At the posterior angle, the shaft has a mediolateral diameter of and a superoinferior diameter of An abrasion (perhaps a cutmark) runs across the external surface distal of the posterior angle. Based on overall morphology (notably the SI flaring of the body distal of the posterior angle), if this rib does derive from a human, it may represent a 10th left side rib. Morphology Little can be added to a discussion of the morphology of the ribs to what has already been said above. It is clear that the ribs of Individual 1 derived from a relatively small person. The shaft dimensions of this individual's ribs are generally smaller than those of Individual 2 and the average values of a small sample of Euro-American males (Table 9). Given that vertebral remains described above also derived from a relatively small
