Outcrop 1, sample 8136 (Devonian of Russian Federation)

Where: Russian Federation (53.1° N, 57.4° E: paleocoordinates 0.5° N, 16.3° E)

• coordinate estimated from map

When: hesperius-optima conodont zone, Lochkovian (419.2 - 410.8 Ma)

• Siyak Horizon

Environment/lithology: lithified, gray limestone

• Similarly to the sections along the Irgizly River, the Ust-Irgizly beds and Siyak Horizons on the banks of the Belaya River do not differ significantly by their lithologies. The boundary interval is represented by grey fine-grained medium-layered limestones with crinoid limestone interbeds. The total thickness of the uncovered interval in the Outcrop 1 is 15 m.

Size class: microfossils
