80cm below top of Unit 9 of the Evtropina Fm, Upper Devonian of Northern Urals (Devonian of Russian Federation)

Where: Northern Urals, Russian Federation (62.7° N, 54.4° E: paleocoordinates 7.7° N, 12.6° E)

• outcrop-level geographic resolution

When: lower to middle Palmatolepis crepida zone, Evtropina Formation, Early/Lower Famennian (376.1 - 370.6 Ma)

• "Evtropiny Noski outcrop is about 330m in length and is formed by a simple, wide syncline, the eastern limb of which is faulted just to the east of the synclinal axis."

Environment/lithology: deep subtidal; brown, gray, green, argillaceous, cherty/siliceous mudstone and shelly/skeletal, black, green, white lime mudstone

• "Evtropina Formation is interpreted as a relatively deep-water, bathyal sequence."
• "dark green, greyish or brownish green argillaceous, cherty shales, thin intercalations of green cherts and white limestones, and some layers of black foraminiferal limestones."
