Outcrop 1, sample 01943 (Silurian of Russian Federation)

Where: Russian Federation (53.1° N, 57.4° E: paleocoordinates 0.0° N, 14.7° E)

• coordinate estimated from map

When: eosteinhornensis s.l. conodont zone, Pridoli (423.0 - 419.2 Ma)

• Ust-Irgizly bed

Environment/lithology: lithified, dolomitic, gray limestone

• The Ust-Irgizly beds occur stratigraphically below the Siyak deposits of the Lochkovian age and correspond to the Přídolí (upper Silurian). They are represented by grey layered and selectively dolomitized organogenic limestones with scarce intercalations of siltstones. The thickness of the horizon ranges from 20 to 40 m.
