FIG. 9. A in A new specimen of the ornithischian dinosaur Haya griva, cross-Gobi geologic correlation, and the age of the Zos Canyon beds

FIG. 9. A. Comparison of IGM 100/3181 (top) with the holotype of Haya griva (IGM 100/2017, bottom). Shared diagnostic characters (Makovicky et al., 2011) are: (1) homodont unserrated premaxillary teeth, (2) the lack of a rugose rhamphothecal pad on the anterior surface of the premaxilla, (3) the presence of a triangular maxillary fenestra, (4) a jugal with a bifurcated (forklike) posterior ramus where it abuts the quadratojugal, (5) the presence of a quadratojugal foramen.

FIG. 4. A in A new specimen of the ornithischian dinosaur Haya griva, cross-Gobi geologic correlation, and the age of the Zos Canyon beds

FIG. 4. A. Premaxillary tooth of IGM 100/3181 in mesial and distal views. Its precise orientation cannot be determined as it was found as float during preparation. B. Cheek tooth of IGM 100/3181. Its precise orientation cannot be determined as it was found as float during preparation, and is compatible with the morphology of both upper and lower teeth of referred Haya specimens.
