Computed results for Rhinoceros are also compared with previous results obtained by visual interpretation (the classic method). Each of the four transformations are interpreted separately as shape change from Subhyracodon. Coordinate data for 21 landmarks, defined in lateral view, are analyzed by the computer program Thinplate Splines. The early Oligocene genus Subhyracodon serves as the primitive shape from which the extant genera ( Dicerorhinus, Rhinocerso, Diceros, and Ceratotherium) have been transformed. Cartesian transformation, applied as a landmark morphometric method, is used to investigate some of the evolutionary shape changes leading to the skulls of the modern rhinoceroses.
