Kryptobaatar,[1] also known as Gobibaatar[1] or Tugrigbaatar,[2] is an extinct mammalian genus dating from the Upper Cretaceous Period and identified in Central Asia. This animal was a member of the extinct order of Multituberculata within the suborder Cimolodonta, and was a member of the family Djadochtatheriidae. It lived contemporaneously with some of the dinosaurs. Its skull had a length of perhaps 3 cm.

The generic name Kryptobaatar is derived from Greek κρυπτός: kruptós, "hidden," (alludes to the ventral position of infraorbital foramen) and Mongolian баатар: baatar, "hero" (alludes to the name of the capital of Mongolia, Ulan Baatar). The specific name dashzevegi is named in honour of Mongolian palaeontologist Demberelyin Dashzeveg. The derivation of its synonym Gobibaatar parvus is Gobi (occurring in the Gobi Desert, Mongolia) and baatar ("a hero", the same as Kryptobaatar).[1] Another synonym Tugrigbaatar saichanensis is a generic name derived from the Toogreeg and Ulan Baatar, and a specific name derived from a Gurvan Saykhan mountain range.[3]
