Fig. 7. Bivariate plots of Phiomia sp. cheek teeth from the BOTM, early Oligocene, Minqar Tibaghbagh, Qattara Depression, Egypt (stars) compared with Phiomia spp. from the early Oligocene Jebel Qatrani Formation, Fayum Depression, Egypt (diamonds) and Phiomia major from the late Oligocene, Chilga Formation of the Chilga Region, Ethiopia (triangles). Comparative dimensions of Phiomia serridens from Matsumoto (1924: 48, tables B, C, E, G); dimensions of Phiomia major from Sanders et al. (2004: table 2). A. M3? (or M2?) and M3?, originally the latter molar would have been larger in width (see text). B. m3, the width is based on estimated dimensions.
