At least 10 (or more) mammal taxa have been identified from the Middle Jurassic (Callovian) Balabansai Formation in northern Fergana Depression, Kyrgyzstan, on the basis of mostly isolated and fragmentary teeth: docodontans cf. Simpsonodon spp., Paritatodon sp. [Paritatodon, gen. nov., is established for ‘Shuotherium kermacki’ Sigogneau-Russell, 1998, from the Bathonian of England], Tashkumyrodon desideratus, Tegotheriidae indet.; and Docodonta indet.; eutriconodontans Amphilestidae indet.; Ferganodon narynensis, cf. Ferganodon sp., and Triconodontidae indet.; ‘symmetrodontan’ Tinodontidae indet.; and cladotherians Paurodontidae indet. and Amphitheriidae indet. The occurrences of Triconodontidae, Tinodontidae, and Paurodontidae in the Balabansai Formation represent the oldest-known records of these groups. The Balabansai mammal assemblage is basically similar to the Bathonian mammals of the Forest Marble in England and the Itat mammal assemblage in Siberia respectively, revealing at present knowledge a marked uniformity of the Middle Jurassic mammal fauna across Laurasia.
