Nutovskaya Suite (middle) - Nutovo River, Okha District, Sakhalin (Pliocene of Russian Federation)

Where: Russian Federation (52.6° N, 143.2° E: paleocoordinates 52.7° N, 142.6° E)

• coordinate based on nearby landmark

• local area-level geographic resolution

When: Nutovskaya Formation (Nutov Group), Early/Lower Pliocene (5.3 - 3.6 Ma)

• STRATIGRAPHIC RELATIONS: From the middle Nutovskaya suite of the "upper Nutov" horizon, which lies below the "Pomyr" (Pliocene) and above the "Okobykay" (Late Miocene) horizons. THICKNESS: Total thickness of unit is unknown. AGE: Pliocene, on the basis of classification into the "Pomyr" horizon. STRATIGRAPHIC POSITION: Composite checklist for middle part of the "formation" in this area.

• formation-level stratigraphic resolution

Environment/lithology: transition zone or lower shoreface; poorly lithified, fine-grained sandstone and poorly lithified claystone

• ENVIRONMENT: Not stated in text; assumed to be cool-water relatively shallow water coastal setting on the basis of faunal composition.
• SPECIFIC LITHOLOGY: Ranges from fine-grained sand to gravel, with layers of limey sandstones, gravels, conglomerates and lignites. LITHIFICATION: Poorly-lithified, assumed on the basis of age and facies.

Size class: macrofossils

Collection methods: COLLECTOR: Unknown, presumably Sokolov and Tikhonovich (c. 1925). REPOSITORY: Unknown repository.
