At first sight it also looks narrower but this is not borne out by Ginsburg & Antunes' measurements of length x breadth (179 x 82 mm) nor by my own measurements from their picture. The dorsal concavity of the tusk is very evident but the width is not sufficient for it to fit an amebelodontine (Tobien 1973: fig. 15). The M3 in the mandible is better preserved and slightly more worn than the very similar Its lophids look less as if they are growing out of a shelf. It is more evenly wide along its length instead of having the third lophid noticeably the widest. The posterior lobes of the pretrite trefoils, consituting the conules which lie centrally between the lophids, are small as in and no larger than in Rusinga M. 15300. These conules appear to be smaller than in M3s from Bugti. The third lophid is less chevroned than in Bugti 1050. Its length/breadth proportion looks similar to the Artenay M3 of G. angustidens (see Gins- burg & Antunes 1966: pi. 3, fig. 2), but the latter looks as if it has less marked anterior conules of the pretrite trefoils and a more obvious shelf from which grow 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 British Museum (Natural History).
