Abstract
A fossil monkey skull recovered from the "Old Alluvium" of presumed Pleistocene age near Wad Medani in the Central Sudan is described. This find represents a variant of Colobus polykomos abyssinicus, a living species whose habitat is restricted to forest canopy. Since this skull is not abraded and is unlikely to have been water-transported more than a few kilometers to its site of burial, it provides evidence that continuous forest cover once reached northwest across the Sudan to the vicinity of Wad Medani.
