Figure 1

The phytogeographical zone IV (Somalia-Masai steppe and shrubland) was occupied by P. boisei and is now occupied by the Papio cynocephalus population used in this study. I Guineo-Congolian humid forest, II Zambezian miombo woodland, III Sudanian woodland, IV Somalia-Masai steppe and shrubland, X–XII transition mosaic of forest/savanna/woodland, VIII Afromontane domain. The location of the A. bahrelghazali sites in Chad falls outside these recognised zones (stippled). Hence, no attempt was made to more accurately assess the possible dietary ecology of this species.
