FIG. 2 in New ctenodactyloid rodents from the Erlian Basin, Nei Mongol, China, and the phylogenetic relationships of Eocene Asian ctenodactyloids

FIG. 2. Stratigraphic distribution of ctenodactyloid taxa in the Huheboerhe-Nuhetingboerhe area, plotted on a composite section modified from Wang et al. (2010). Fossil horizons are denoted as, in ascending order, NM-1 to NM-4 in the Nomogen Formation, AS-1 to AS-6 in the Arshanto Formation, and IM-1 to IM-2 in the Irdin Manha Formation) (modified from Wang et al., 2010: fig. 2). Black squares indicate occurrences of ctenodactyloid species from the fossil horizons that were described in this study.
