[Gobiconodon sp.(2) PSS-MAE 137, anterior fragment of a right dentary; PSS-MAE 138, posterior fragment of a right dentary, PSS-MAE 137 and PSS-MAE 138 , represent a second gobiconodontid taxon at Oshih. Both were found at the same locality where the lower jaw fragment of Gobiconodon hopsoni was discovered. These two specimens, the proximal and distal portions of a right lower jaw, were found a few inches away from each other and may belong to the same individual.
The original name of the Oshih Formation (Berkey and Morris, 1927) is considered in the Russian literature (Shuvalov, 1975) as part of the Tevsh (Undurukhin) Svita.
