Figure 11. Morphological comparison amongst right scaphoids of four coeval fossil rhinocerotids (Early Miocene) referred to the genera Pleuroceros Roger, 1898 and Mesaceratherium Heissig, 1969, in lateral view. A, Pleuroceros blanfordi (Lydekker, 1884), Zinda Pir Dome, Pakistan; B, Pleuroceros pleuroceros (Duvernoy, 1853), Aquitaine Basin, France. 1. posterior height nearly equals anterior height; 2. robust and low bone; 3. shallow radial notch; 4. mediodistal tuberosity (thick in P. blanfordi but absent in P. pleuroceros); 5. small trapezium-facet; 6. flat magnum-facet; 7. prominent postero-proximal semilunate-facet; 8. no edge between anterodistal semilunate- and magnum-facets; C, Mesaceratherium welcommi sp. nov., Zinda Pir Dome, Pakistan; D, Mesaceratherium paulhiacense (Richard, 1937), Aquitaine Basin, France. 1. posterior height much exceeding anterior height; 2. slender and elevate bone; 3. deep radial notch; 4. small mediodistal tuberosity; 5. large trapezium-facet; 6. concave magnum-facet; 7. no posteroproximal semilunate-facet (smooth pad); 8. sharp edge between anterodistal semilunate- and magnum-facets. (B) and (D) modified after de Bonis (1973). Scale bar = 2 cm.
