Description
Fig. 1. Didelphis marsupialis (AMNH 21439) and Metachirus nudicaudatus (AMNH 244617), axis in lateral view. The spinous process (Sp) in Metachirus is posteriorly extended (ch. 10[1]), whereas in Didelphis it is not extended beyond the neural arches (Na) (ch. 10[0]). In Didelphis, the anterior extension of the dens (de) is barely anterior to the anterior tip of the spinous process (ch. 11[0]), whereas in Metachirus the dens is cranialy extended (ch. 11[2]). The ventral tubercle (Vt) is a uniform crest in Didelphis (ch. 14[0]), whereas in Metachirus it forms two protruding lobes (ch. 14[1]). Other abbreviations: As, articular surface; Tc, transverse canal; Tp, transverse process. Scale bars: 10 mm.
