Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| E. A. Zvonok and I. G. Danilov 2017 | (1) Orbits directed laterally and slightly anteriorly. (2) Frontals contributing to the orbital margins. (3) The secondary palate reaches between half and two thirds the distance between the anterior margin of the skull and the fossa temporalis inferior. (4) Labial ridge of the upper jaw is vertical and sharp. (5) Vomer hexagonal in outline and in a wide contact with the palatines on the secondary palate. (6) Pterygoids broad anteriorly and with posterolaterally oriented external processes. (7) Length of the mandibular symphysis about one third the length of the mandibular ramus. (8) Triturating surface of the lower jaw with labial, lingual, and sym- physeal ridges. (9) Plastron with wide axillo-inguinal distance (plastral bridge).
