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]
Species identified
- Kryptobaatar dashzevegi Kielan−Jaworowska, 1969. At Djadokhta Formation, Ukhaa Tolgod, Tögrög Shiree and Bayan Zag or Baruungoyot Formation, Red beds of Hermiin Tsav, Mongolia. Stage: 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. Gobibaatar parvus Kielan−Jaworowska, 1969 and Tugrigbaatar saichanensis Kielan−Jaworowska & Dashzeveg, 1978 are now treated as synonyms of K. dashzevegi by Kielan-Jaworowska et al. (2003).[4]
- Kryptobaatar mandahuensis Smith, Guo & Sun, 2001. At Bayan Mandahu Formation, Urad Houqi Banner, Inner Mongolia, China. Based on several well-preserved skulls. This location is about the same stage as the Djadokhta Formation of Mongolia, Campanian (Upper Cretaceous).[4]
