The range values of PTDa, PAPDa, DAPl, DTDa and TDfo for the humeri of D. megarhinus (N = 3) and S. jeanvireti (N = 4) are based on the material studied at NMB. The range values of PTDa, PAPDa, DAPl, DTDa and TDfo for the humeri of S. etruscus are from Fortelius et al. (1993)
PTD proximal transverse diameter, PAPD proximal antero-posterior diameter, PTDa transverse diameter of the proximal articular surface, PAPDa antero-posterior diameter of the proximal articular surface, TDM minimal transverse diameter of the diaphysis, APDM antero-posterior diameter of the diaphysis, DTD distal transverse diameter, DAPDm distal antero-posterior diameter of the medial side, DAPl distal antero-posterior diameter of the lateral side, DTDa distal transverse diameter of the throclee, TDfo transverse diameter of the oleocranic fossa
