APPENDIX 3 in Cranial morphology and phylogenetic relationships of Amynodontidae Scott & Osborn, 1883 (Perissodactyla, Rhinocerotoidea)

APPENDIX 3. — Body masses were estimated using regression equations for perissodactyls and for ungulates of Legendre (1989) or/and regression equation for Rhinocerotidae Owen, 1845 and for all ungulates of Fortelius & Kappleman (1993).
