Tuvaechonetes Community, Baital Formation, W. Tuva (Silurian to of Russian Federation)

Where: Russian Federation (51.0° N, 92.0° E: paleocoordinates 36.1° N, 9.2° E)

• coordinate estimated from map

• local area-level geographic resolution

When: Pichishui Member (Baital Formation), Ludlow to Ludlow (427.4 - 419.2 Ma)

• Ludlovian-Pridolian; Baital Formation, Pichi-Shui beds.

• member-level stratigraphic resolution

Environment/lithology: marine; gray, green, calcareous siltstone

• "BA 2 'Chonetid Community' in Boucot's (1975) sense. Lithology suggests quiet conditions of only normal current activity consistent with largely disarticulated condition of most shells."
• "Occurs as mostly disarticulated specimens...in greenish-gray, calcareous siltstone.."

Size class: macrofossils
