   Abstract:
   Knowledge of African terrestrial mammals during the Paleogene is limited to 12 sites, most of which are in North Africa. Only one of these, the Fayum region of Egypt, has produced an extensive mammalian record. The Eocene/Oligocene boundary has been difficult to identify in Africa because of the high proportion of unique endemic taxa, the lack of radiometrically datable rocks at appropriate stratigraphic positions, and other problems. To obtain an estimate of the boundary, the geology and mammalian fauna of the Fayum is analyzed, especially with respect to: 1) faunal change through time; 2) faunal correlations between the Fayum and other sites in Africa; and 3) the stratigraphic positions of major erosional unconformities and inferred regressive events of the Tethys Sea. -from Authors
