Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| Z. Kielan-Jaworowska and J. H. Hurum 1997 | Type species of Kryptobaatar that differs from K. saichanensis
in having the mandibular condyle placed at the level of the molars and facing posterodorsally, the palatal part of the premaxillary-maxillary suture placed at the level of P2, and consequently a longer premaxilla. The M1 is shorter than in K. saichanensis and there are 3:2 cusps in m2. | |
| Z. Kielan-Jaworowska and J. H. Hurum 1997 (Kryptobaatar saichanensis) | Differs from K. dashzevegi in having M1 slightly longer and 4:2
cusps in rn2 (3:2 in K. dashzevegi), in having the palatal part of the premaxillary-maxillary suture in front of P1 rather than at the level of PI, possibly a smaller glenoid fossa, placed more laterally, on a longer stem, and in having a smaller mandibular condyle, facing more dorsally, with its ascending ramus longer and directed more laterally |
