Collection methods: bulk, quarrying, surface (in situ), mechanical, sieve,

• Itatodon tatarinovi material housed in the Paleontological Museum of Tomsk State

•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.

•The specimens described here are housed in the Borissiak Paleontological Institute of the Russian Academy of Sciences, Moscow (PIN).

•"...other specimens were collected in 2010–2012 during a joint Russian-German expedition to Berezovsk Quarry. The edentulous jaw fragments were found in the field while picking the coarse fraction of fossiliferous concentrate obtained from screenwashing of ∼12.5 tons of matrix" (Avaerianov et al. 2014)"
