Fossil mammals of the Shinzhaly fauna occur in the Kolpak Formation, a sequence of Paleogene red beds exposed along the Shinzhaly River in Eastern Kazakstan. Most of the fossils are concentrated in a single bed 0.3 m thick. Screen washing of sediment from this bed has yielded small mammals, including several species of rodents: a zapodid, Aksyiromys dalos; two cricetids, Pappocricetodon kazakstanicus, sp. nov. and Zhungaromys gromovi, gen. et sp. nov.; and a chapattimyid, Saykanomys sp., cf. S. bohlini. Temporal correlation indicated by the rodents is in agreement with the middle Eocene (Irdinmanhan) age indicated by perissodactyls previously described from the Shinzhaly fauna.
