Where: Russian Federation (51.2° N, 142.7° E: paleocoordinates 52.4° N, 140.1° E)
• coordinate based on nearby landmark
• local area-level geographic resolution
When: Pilengskaya Formation, Late/Upper Oligocene (28.4 - 23.0 Ma)
• STRATIGRAPHIC RELATIONS: From the Pilengskaya suite of the lower "Daekhuriin" horizon, which lies below the "Uynin" (Early Miocene) and above the "Machigar" (Early Oligocene) horizons.
