Atrypa hedei Community, Dashtygoi Beds, W. Tuva (Silurian of Russian Federation)

Where: Russian Federation (51.0° N, 92.0° E: paleocoordinates 31.9° N, 14.0° E)

• coordinate estimated from map

• local area-level geographic resolution

When: Dashtygoi Beds Formation, Wenlock (433.4 - 427.4 Ma)

Environment/lithology: marine; siltstone and argillaceous, calcareous siltstone

• "[Well preserved, articulated shells.] [Preservation and occurrence] suggest soft substrate in relatively quiet area. BA 3."
• "Occurs in siltstone (aleurolite)...Less common Meristina, Eospirigerina, and Trimerella occur in calcareous, argillaceous siltstone."
