Diagnosis
ReferenceDiagnosis
Z. Kielan-Jaworowska and J. H. Hurum 1997Member of Djadochtatheria with a relatively wide and rectangular anterior part of the snout and anterior part of the zygomatic arches varying in position from roughly transverse to posterolateral. Differs from other djadochtatherians in having up to five, asymmetrically arranged pairs of vascular foramina on the nasals and the foramen ovale divided into five foramina. Differs from all the djadochtatherians in having M1 with a smooth inner ridge extending along the length of the tooth, rather than a short ridge extending for a half of the tooth length, or a row of cusps. Differs from Sloanbaatar and Djadochtatheriidae in having the zygomatic arches moderately expanded laterally and in this respect it resembles Nemegtbaatar and Chulsanbaatar. Shares with Sloanbaatar and Nemegtbaatar a relatively narrow glenoid fossa, although the details of its shape are different than in these taxa (Fig. 11). Shares with Sloanbaatar and Nessovbaatar a relatively low coronoid process, that flares laterally. Shares with most djadochtatherian, except for Kryptobaatar, Nemegtbaatar, and Chulsanbaatar, the mandibular condyle situated above the occlusal level of the molars and facing dorsally.
