Mutationella podolica-Leptotrypella semiramosa Comm.,SW Byelorussia (Devonian of Belarus)

Where: Belarus (52.0° N, 24.0° E: paleocoordinates 17.2° S, 6.6° E)

• coordinate estimated from map

• local area-level geographic resolution

When: Lochkovian (419.2 - 410.8 Ma)

• "A Lochkovian analog of the Podolian Chortkov Horizon." Dubits and Orchov Formations.

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

• "The entire sequence clearly reflects up section regression of the marine basin."
• "The upper portion of the Dubits Formation (416.5 to 432.0 m) is composed of the same greenish-grey marls and shales, with laminae and lenses of marlstone, as its lower parts but fossils are less abundant. Up section their quantity gradually decreases. The Orchov Formation is made up of interbedded greenish gray marls and shales with intercalations of siltstones, sandstones, and dolomites. Fossils are practically absent."

Collection methods: core

• Abundances given for dominant brachiopods and bryozoans.
