Diagnosis
ReferenceDiagnosis
Z. Kielan-Jaworowska and J. H. Hurum 1997Skull length about 50-55 rnm, ml cusp formula 4:3. Differs from Kryptobaatar in being distinctly larger; shares with Kryptobaatar and Catopsbaatar similar shape of the snout. Shares with Kryptobaatar presence of four upper premolars and arcuate p4. The p4 is only insignificantly longer than ml. Differs from Catopsbaatar and Tombaatar in having four, rather than three upper premolars. Shares with Catopsbaatar very long postorbital process and robust lower incisor, but differs from it in having the orbit placed somewhat more anteriorly, and relatively larger and arcuate p4 (subtrapezoidal in Catopsbaatar).
