Description

Figure 1. Holotype of Mirusodens caii gen. et sp. nov. (HT-B-PM-0001). A, main part (part A or 'less part' when referring to anatomic orientation of the split skeleton) in which most cranial structures and upper teeth were preserved; B, counterpart (part B or 'right part') in which most lower teeth were preserved. Red boxes 1–7 correspond to figure panels A–G in Figures 6 and 8–10 and to A–D in Figure 5. Note that the skeleton is preserved in association with numerous valves of conchostracans that are typical invertebrate fossils in the Daohugou strata. The dark area probably represents residues of the pelage, possibly the patagium (see Figs 5 and 6 for comparison with extant gliding mammals). Abbreviations: l-fe, less femur; l-fi, less fibula; l-hu, less humerus; l-I2, less and presumably the second upper incisor; l-ra, less radius; l-ti, less tibia; l-ul, less ulna; r-I2, right and presumably the second upper incisor.
