Diagnosis
ReferenceDiagnosis
Z. Kielan-Jaworowska 1994Dental formula 2032/ 1022. Generally similar to Djadochtatherium, from which it differs in being larger, in having only three (instead of four) upper premolars (P2 being lost), and in having a smaller and less vaulted p4. Differs from Taeniolabis and Lumbdopsalis in having three rather than only one upper premolar. Differs from Catopsalis calgariensis, Taeniolabis, Prionessus and Lambdopsalis in having P4 double-rooted rather than single-rooted. Differs from Catopsalis, Taeniolabis, Prionessus and Lambdopsalis in having two (p3 and p4) lower premolars, rather than only p4, and in having the apical crest of p4 rounded rather than triangular. Differs from Catopsalis alexanderi, Taeniolabis and Prionessus in having I3 located near the middle part of the premaxillae, just lateral to the palatine fissures, rather than on the margins of the premaxillae. Differs from Prionessus, Catopsalis and Lumbdopsalis in having quadrangular rather than crescent-shaped molar cusps. Differs from Sphenopsalis in having quadrangular molar cusps, instead of slender, compressed and shearing. Differs from Catopsalis, Prionessus, Taeniolabis, and Lumbdopsalis in having a smaller number of cusps on the lower and upper molars. Differs from Kamptobaatar in being much larger, in having three rather than four upper premolars, in having M1 with three rows of cusps, rather than two rows and a medial ridge, and in having a greater number of cusps on the upper and lower molars.
