Figure 6 in A Late Cretaceous diversification of Asian oviraptorid dinosaurs: evidence from a new species

Figure 6. Skull comparisons of oviraptorosaurs showing relative positions of the posterodorsal corner of the antorbital fenestra and the anteroventral corner of the external narial opening. (a) Incisivosaurus gauthieri; (b) Conchoraptor gracilis; (c) Wulatelong gobiensis; (no scale) (d) Banji long; (e) Anzu wyliei; (f) Khaan mckennai; (g) Citipati osmolskae; (no scale) (h) Huanansaurus ganzhouensis (reversed); (i) Yulong mini; (j) Oviraptor philoceratops; (k) Nemegtomaia barsboldi; l: “ Oviraptor ” mongoliensis; m: Tongtianlong limosus gen. et sp. nov. (a, b, f, g, j, k) and l are from Lü 23; (c) is modified from Xu et al. 18; (d) is modified from Xu and Han 26; (e) is modified from Lamanna et al. 41 (reversed), (i) is from Lü et al. 10 and (h) is from Lü et al. 29. External narial opening is in red, and antorbital fenenstra is in yellow. Note: The horizontal line projected through the posterodorsal corner of the antorbital fenestra is parallel to the line linking the articular end of the quadrate and the ventral margin of the premaxilla.
