Fig. 12 in The last erythrosuchid-a revision of Chalishevia cothurnata from the late Middle Triassic of European Russia

Fig. 12. Reconstruction of maxilla and left nasal of erythrosuchid archosauriform Chalishevia cothurnata Ochev, 1980, in articulation as preserved (A), and close to the articulation reconstructed by Ochev (1980). This reconstruction produces a strongly downturned nasal, but is incorrect due to damage to the nasal between the main body and the ventral process. An alternative reconstruction (B) shows a more anteriorly directed nasal, providing space to accommodate a Shansisuchus-like premaxilla and a larger accessory antorbital fenestra.
