Kryptobaatar^[1] ("hidden hero," from Greek: kryptos, "hidden," and Mongolian: baatar, "hero" or "athlete") and also known as Gobiaatar, Gobibaatar ("Gobi hero")^[2] or Tugrigbaatar^[3] 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.

[edit] Species identified

• Kryptobaatar dashzevegi (Kielan-Jaworowska Z, 1970). At Djadokhta Formation, Ukhaa Tolgod and Tögrög Shiree, Mongolia. Age: lower Campanian or Upper Cretaceous. The skull has a length of perhaps 3 cm. The front teeth look impressively sharp and not much like those of a strict vegetarian.

• Kryptobaatar gobiensis, also known as Gobibaatar parvus (Kielan-Jaworowska Z, 1970), from the Upper Cretaceous, from the Gobi Desert, Mongolia.

• Kryptobaatar mandahuensis Smith T, Guo D-Y & Sun Y, 2001. It is from the Campanian (Upper Cretaceous) strata of the Bayan Mandahu red beds, Inner Mongolia, China. Based on several well-preserved skulls. This location is about the same age as the Djadokhta Formation of Mongolia.

• Kryptobaatar saichanensis (Kielan-Jaworowska Z & Dashzeveg D, 1978), also known as Tugrigbaatar saichanensis (Kielan-Jaworowska Z & Dashzeveg D. 1978) from the Upper Cretaceous of Mongolia.
