Where: France (50.8° N, 1.8° E: paleocoordinates 22.1° S, 3.5° E)
• coordinate based on nearby landmark
• local area-level geographic resolution
When: Fiennes Member (Ferques Formation), Frasnian (382.7 - 372.2 Ma)
• middle asymmetricus conodont zone
• member-level stratigraphic resolution
Environment/lithology: marine; brown dolomite and dolomitic sandstone
• "The Blacourt Formation is a compact, massive bedded, black fossiliferous marine limestone, with argillaceous layers and some small reefs in the Griset Member. The lower [Cambreseque] and upper [Patures] member of the Beaullieu Formation are mainly terrigenous ["shale" mentioned in figure caption], except for its lowest beds, the so-called Cedule Limestone. The middle [Noces] member consists of dolomite lenses, passing upward into shales, and to a reef build-up capped by fossiliferous limestones. The base of the lower [Fiennes] member of the succeeding Ferques Formation is a biostromal dolomite overlain by yellow, then brownis-dark dolomite and dolomitic sandstones. These are overlain by the fully marine fossiliferous Ferques Limestone. The lower part of the [second-from-bottom] Bois Member and the upper part of the [third-from-bottom] Parisienne Member are biostromal. In the upper [Gris] member, sediments are more argillaceous..."
