DESCRIPTION
Mandible
BPB 8 ( Fig. 22A, B View FIG ). This fossil (maximum length: 20.8 mm; height: 20 mm) is the distal part of the ascending ramus and the mandibular condyle of a right mandible. The median part of the condyle is damaged and the lateral part is very salient (length: 9.3 mm; breadth: 16.6 mm).
BPB 26 ( Fig. 22C, D View FIG ). The preserved part (maximum length: 26.1 mm; height: 24.7 mm) comprises the ascending ramus and the mandibular condyle (maximum length: 7.8 mm; preserved breadth: 6.4 mm) of a right mandible.
Post-cranial bone
BPB 19 ( Fig. 22E, F View FIG ). This right intermediate manual phalanx presents a big crack latero-distally to medio- proximally and it has lost a fragment latero-distally and a dorsal flake of bone latero-proximally which has damaged the proximal articular facet. The phalanx is short and presents a flat aspect (length: 15 mm; mid-shaft thickness: 3.2 mm). The intermediate phalanges of the hand and foot of colobines and Papio present nearly the same size and almost the same aspect except that they are slightly flatter in the hand ( Begun et al. 1994). The proximal extremity is slightly larger (preserved breadth: 6.9 mm, height: 5.4 mm) than the distal extremity (breadth: 6.1 mm, height: 4.1 mm). The proximal articular facet presents a double concavity as is usual in a median phalanx. In dorsal view ( Fig. 22E View FIG ), a small hole is present in the distal extremity and corresponds probably to a predator mark. In volar view ( Fig. 22F View FIG ), along all the shaft, there are extensions underlined by deep depressions which correspond to the insertion of collateral ligaments of the manual interphalangeal joint. The central part of the shaft is convex medio-laterally and forms a pillar. The proximal extremity presents a smooth bulge on each side. There is a small oval cavity which possibly corresponds to a mark of predation. The distal extremity presents a trochlear aspect. In plantar view, the medial condyle of this trochlea is the narrower and the more convex of the two condyles. It is not possible to say more about this phalanx.
