The two right scaphoids, , are less thickset than examples from Pikermi probably belonging to Diceros pachygnathus. There is only poor development of a downwards projection posteroventrally and this may be a resemblance to Dicerorhinus rather than to Aceratherium (see Bonis 1973: fig. 36). The complete left femur, , is about the size of Pikermi examples but more gracile especially at the distal end. The third trochanter is smaller and higher on the shaft and in lateral view the top of the great trochanter slopes downwards anteriorly. These are additional differences from the Pikermi bones and the downward slope of the great trochanter may be linked with the third trochanter appearing to be higher on the shaft. The Arabian femur is not quite so long as a cast of an Eppelsheim femur (, labelled D. schleiermacheri), on which the great trochanter has a similar slope and the third trochanter is about the same size as the Arabian one. The left tibia, , is the size of the Dicerorhinus leakeyi and D. orientalis listed in Hooijer (1966: 171, table 40) but a bit longer than the D. schleiermacheri. It is about the size of a rhinoceros tibia 27458 from Sansan, but less gracile as shown by the wider distal part of the shaft and distal articular surface. Compared with Pikermi rhinoceros tibiae it is slightly more gracile, the tibial tuberosity at the proximal end is less massive in proximal view and in anterior view there is less of a deep groove at the proximal end.
