Diagnosis
ReferenceDiagnosis
Z. Kielan-Jaworowska and J. H. Hurum 1997Type 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
