Diagnosis
ReferenceDiagnosis
Z. Kielan-Jaworowska and J. H. Hurum 1997Family of Djadochtatheria that differs from all other multituberculates (and all other mammals) in having a subtrapezoidal snout in dorsal view, with wide anterior margin and lateral margins confluent with zygomatic arches rather than incurved in front of the arches. Djadochtatheriidae differ from other members of Djadochtatheria in having the snout extending for 50% or more of the skull length, anterior part of promontorium (sensu Hurum et al. 1996) irregular, with incurvatures on both sides, rather than oval (a character shared with Lambdopsalis). They share with Chulsanbaatar two pairs of vascular foramina on the nasals and share with Chulsanbaatar, Kamptobaatar, and Taeniolabididae lack of palatal vacuities.
