Mesotrypa esthonica-Eoplectodonta penkillensis Comm., SW Byelorussia (Silurian of Belarus)

Where: Belarus (52.0° N, 24.0° E: paleocoordinates 27.3° S, 2.9° E)

• coordinate estimated from map

• local area-level geographic resolution

When: Monoclimacis griestoniensis - Monoclimacis crenulata graptolite zone, Zel’van Formation, Telychian (438.5 - 433.4 Ma)

• M. greistonensis-M. crenulata Zones.

• formation-level stratigraphic resolution

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

• "The Z. Formation rests unconformably, transgressively over Middle Ordovician sediments, and grades into the marls and nodular limestones and limestones of the overlying, Wenlock Lipno Formation. Brachiopods and bryozoans are very rare in the Lipno, which is why communities have not been described from it. (For the time being they are considered as a Leangella-Glassia Association.) This is probably a BA 4-5 unit..."
• "Occurs in greenish-gray shales and marls, in dark, grayish-green argillites with graptolites and in marlstones."

Size class: macrofossils

Collection methods: core

• Abundances given for dominant brachiopods and bryozoans.
