•University, Tomsk, Russia (PM TGU), and in the Paleontological Institute of the Russian Academy of Sciences, Moscow, Russia (PIN)

•2010-2012 collection by a Joint Russian-German expedition: "The newly collected mammal specimens were obtained during screen-washing of ~12.5 tons of matrix. The jaw fragments were found in the field by picking the coarse fraction of fossiliferous concentrate. The teeth were recovered during sorting of the fine fraction in the laboratory.
