Kryptobaatar is a mammal genus known from the Upper Cretaceous of Central Asia. It lived alongside some of the dinosaurs. This animal was a member of the extinct order of Multituberculata.
For those of a technical disposition, it's within the suborder of Cimolodonta, and a member of the family Djadochtatheriidae.
Genus: Kryptobaatar Kielan-Jaworowska Z, 1970
'hidden hero'
Aka: Gobiaatar, Gobibaatar ('Gobi hero') Kielan-Jaworowska Z, 1970; Tugrigbaatar Kielan-Jaworowska Z & Dashzeveg D, 1978
Remarks: "Gobibaatar has page priority but was selected as the junior synonym by Kielan-Jaworowska in 1980," (McKenna & Bell, 1997).
Species: Kryptobaatar dashzevegi Kielan-Jaworowska Z, 1970
Place: Djadokhta Formation, Ukhaa Tolgod and Tögrög Shiree
Country: Mongolia
Age: ?lower Campanian, Upper Cretaceous
Remarks: The skull has a length of perhaps 3cm. I’m no expert, but the front teeth look impressively sharp and not much like those of a strict vegetarian.
