Where: Alsace, France (43.4° N, 3.1° E: paleocoordinates 30.8° S, 23.5° E)

• coordinate based on nearby landmark

• outcrop-level geographic resolution

When: Coumiac Formation, Late/Upper Frasnian (379.5 - 376.1 Ma)

• Frasnian part is in Middle Coumiac Formation, beds 23 through 31, zones "12" and "13". Famennian part is mainly in Upper Coumiac Formation, but also a bit of the Middle Coumiac Formation, and extending up into the Lower Griotte Formation, Triangularis Zone and extending up into the Crepida zone.

• formation-level stratigraphic resolution

Environment/lithology: marine; red lime mudstone

• "The sequence is one of pelagic calcilutites, mostly red tinted and well bedded..."

Size class: macrofossils
