''Chulsanbaatar'' is a genus of mammal from the Cretaceous of Mongolia. It lived during the Mesozoic, also known as the "age of the dinosaurs." This small creature was a member of the extinct order of Multituberculata and is within the suborder Cimolodonta. The genus ''Chulsanbaatar'' was named by Kielan-Jaworowska Z. in 1974. Fossil remains of the species ''Chulsanbaatar vulgaris'' have been found in strata dating to the Campanian (Upper Cretaceous) in the Red Beds of Hermiin Tsav (also known as Khermeen Tsav, part of the Barun Goyot Formation) in Mongolia. This creature was a small multituberculate with a 2 cm skull. The jaw would fit on a fingertip. Remarkably, it has been possible to study the ear bones, which shows how well some of the fossils are preserved. ''Chulsanbaatar'' is now a resident of the Polish Academy of Science in Warsaw, Poland. (e.g. ZPAL MgM-1/84). There are a fair number of specimens in the collection, which doubtless accounts for the species name (vulgaris = common). == References == * Kielan-Jaworowska (1974), "Multituberculate succession in the Late Cretaceous of the Gobi Desert (Mongolia)".
