Where: Irkutsk, Russian Federation (53.1° N, 107.2° E: paleocoordinates 53.7° N, 106.8° E)
• coordinate estimated from map
When: Tagay Khalagay Formation, MN 5 (16.0 - 13.7 Ma)
• "While current data indicates correlation of Tagay fauna with Chinese Shangwangian faunas and its correlation with MN 5 of the European Neogene Mammal biochronological system (Steininger, 1999), wider estimates in the range of early to middle Miocene have also been published (Daxner-Höck et al., 2013; Qiu et al., 2013)." - Tentatively marked as MN5 here since in the GTS 2012 it spans the early to middle Miocene anyway.
