Kryptobaatar
Template:Short description Template:Automatic taxobox
Kryptobaatar,Template:Sfn also known as GobibaatarTemplate:Sfn or Tugrigbaatar,[1] 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 Script error: No such module "Lang".: kruptós, "hidden," (alludes to the ventral position of infraorbital foramen) and Mongolian Script error: No such module "Lang".: 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).Template:Sfn 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.Template:Sfn
Species identified
- Kryptobaatar dashzevegi Kielan−Jaworowska, 1969Script error: No such module "Check for unknown parameters".. 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, 1969Script error: No such module "Check for unknown parameters". and Tugrigbaatar saichanensis Kielan−Jaworowska & Dashzeveg, 1978Script error: No such module "Check for unknown parameters". are now treated as synonyms of K. dashzevegi by Kielan-Jaworowska et al. (2003).Template:Sfn
- Kryptobaatar mandahuensis Smith, Guo & Sun, 2001Script error: No such module "Check for unknown parameters".. 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).Template:Sfn
Biology
Kryptobaatar was a hopping species, similar to a modern Jerboa.[2] It is thought to have been a carnivory-oriented omnivore.[3][4]
