Figure 3 in Evolution of South American mammalian predators (Borhyaenoidea): anatomical and palaeobiological implications

Figure 3. General morphology of the manus in various borhyaenoids, focusing on the first metacarpal and associated proximal phalanx, showing the asymmetrical metacarpophalangeal joint. A, Cladosictis patagonica PU 015046 (manus as found in matrix); proximal phalanx in dorsal and proximal views, Mc I is in dorsal and ventral views. B, Sipalocyon gracilis PU 015154 (manus as found in matrix); proximal phalanx in proximal view. C, Lycopsis longirostris UCMP 38061 (association of phalanges is conjectural); proximal phalanx in dorsal, ventral and proximal views, Mc I in dorsal, ventral and distal views. D, Thylacosmilus atrox FMNH P 14531 (association of phalanges is conjectural); Mc I in dorsal, ventral and distal views. Not to scale.
