A, occlusal view of right M'~3, B, occlusal view of left dP4, C, occlusal and lateral views of right P3, D, occlusal view of right M3 in mandible, E, lateral view of another right mandible with M, is a left dP4 in late middle wear with an occlusal length of 9-3 mm (Fig. 46B). It has a notably large parastyle and a cingulum on its lingual lobes. The strong parastyle and the convergent front and back walls of the tooth suggest it is a dP4 and not a molar. Thomas et al. (1982: 127) have reported a similar-sized Dorcatherium from Al-Sarrar. A right and a left astragalus (; , Fig. 48D), a left naviculocuboid plus ectocuneiform () and a proximal left metatarsal () have tragulid morphology and are about the size of D. pigotti. Dorcatherium, larger sp. Fig. 48A-C A further left astragalus, (Fig. 48C), is larger than those assigned to the above Dor- catherium sp. and matches the size of D. chappuisi Arambourg of the east African early Miocene (see Whitworth 1958: 4). Much of a left tibia including the distal end, (Fig. 48A, B), could also belong here. It is larger than the tibia of the living Hyemoschus aquaticus and the distal articular facet is longer anteroposteriorly and less wide transversely. These proportions are nearer to those of Suidae and therefore presumably nearer to the ancestral state. The total length of the tibia would have been in the region of 150 mm. Infraorder PECORA Linnaeus, 1758 Superfamily GIRAFFOIDEA Simpson, 1931 Genus CANTHVMERYX Hamilton, 1973 Canthumeryx sp. Fig. 48E A much damaged but practically complete giraffoid left metatarsal, , is about 320- 330 mm long and about 36 mm wide across its distal condyles. It is close in size to the.
