Where: Russian Federation (52.6° N, 143.2° E: paleocoordinates 53.4° N, 141.2° E)

• coordinate based on nearby landmark

• local area-level geographic resolution

When: Pil'skaya Formation, Early/Lower Miocene (23.0 - 16.0 Ma)

• STRATIGRAPHIC RELATIONS: From the Pil'skaya suite of the lower "Dagi" and "Uynin" horizons, which lies below the "Okobykay" (Late Miocene) and above the "Kholmsk" (Late Miocene) horizons. THICKNESS: Total thickness of unit is 980 m. AGE: Early Miocene, on the basis of classification into the "lower Dagi/Uynin" horizon. STRATIGRAPHIC POSITION: Composite checklist for the "formation" in this area.
