Abstract: Limb bones (mainly distal elements) of Elasmotherium caucasicum, which belong to the Nihewan collection in Tianjin Natural History Museum , are described and discussed in detail herein. Previously , the material of Elasmotherium was relatively rare, especially its limb bones. The rhinocerotid fossils from the Nihewan fauna include Dicerorhinus yunchuensis , Coelodonta nihowanensis, and Elasmotherium caucasicum , but the first two species are much smaller than the last one in size. The material from Nihewan reveals additional limb bone characters for the genus Elasmotherium. Compared with the known limb bones of E. caucasicum, the specimens from Nihewan are identical with them. On the basis of the limb bones of E. caucasicum from Nihewan , a more complete comparison shows that E. caucasicum and E. sibiricum have many common characters but some differences in morphology. Most characters of the limb bones of E. caucasicum from Nihewan are derived , but some are primitive, which is consistent with its phylogenetic position.
