When was evidence of the Catopsbaatar first found?
Catopsbaatar
Kielan-Jaworowska originally classfied Catopsbaatar as a member of the multituberculate family Taeniolabididae in 1974.[1] In 1994, she suggested that Djadochtatherium was close to Catopsbaatar's ancestry.[7] She and Hurum named a new family of multituberculates, Djadochtatheriidae (which they placed in the new suborder Djadochtatheria), in 1997. The family included the genera Djadochtatherium, Catopsbaatar, Kryptobaatar, and Tombaatar, all from the Gobi Desert. The family differs from other multituberculates (and other mammals) in that the front margins of its snout were confluent with the zygomatic arches (cheekbones), giving the snout a trapezoid shape when seen from above. In general, other mammals have snouts where the side margins are curved inward in front of the zygomatic arches.[13] Kielan-Jaworowska and Hurum revised the higher ranks within Multituberculata in 2001, replacing the suborder Djadochtatheria with the superfamily Djadochtatherioidea (placed in the suborder Cimolodonta).[14]
