Coumiac Frasnian/Famennian boundary stratotype, Frasnian part (Devonian of France)
Where: Alsace, France (43.4° N, 3.1° E)
• Paleocoordinates: 32.9° S, 3.8° E (Wright 2013)
• coordinate based on nearby landmark
• outcrop-level geographic resolution
When: Coumiac Formation, Late/Upper Frasnian (375.2 - 372.1 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
