It should be emphasized that the extinct forms that have been placed with remarkable unanimity in Dicerorhinus by palaeomammalogists (including myself) almost certainly represent various shorter and longer lineages, and that none of them apparently is intimately bound up with the extant Dicerorhinus sumatrensis (Fischer) whose pre-Pleistocene ancestry is as yet unknown. These fossil species are important stratigraphically, and certainly inter-related more closely with each other than with the species of rhinocerotids with which they may be found associated at the Old World Tertiary and later sites that yield them.
Among the surviving species of rhinocerotids we do find the greatest dental and skeletal resemblance to these fossil forms in the species Dicerorhinus sumatrensis (Fischer), which may truly be said to represent a Miocene stage in the evolution of the dicerorhine rhinoceroses, and which is definitely not the most advanced among the cluster of species in the genus Dicerorhinus as understood by palaeontologists.
