Dicoelosia biloba-Ptychopleurella lamellosa Comm. in Sutkai Beds, Grauzai-105 bo (Silurian of Lithuania)

Where: Lithuania (55.3° N, 23.2° E: paleocoordinates 20.9° S, 1.0° E)

• outcrop-level geographic resolution

When: Sutkai beds Member (Paprieniai Formation), Wenlock (433.4 - 427.4 Ma)

• group of beds-level stratigraphic resolution

Environment/lithology: marine; gray, green marl and limestone

• "Widespread in greenish-gray marls with microcrystalline limestone interbeds of the fourth facies zone. The articulation data indicates quiet to normal turbulence level, suggesting normal oxygen level (greenish-gray sed. color.). This is BA 4-5 community type."

Collection methods: I have lumped four levels in the borehole and have omitted the data on absolute and relative abundance.
