Where: France (46.3° N, 2.8° E: paleocoordinates 2.1° S, 15.4° E)

• coordinate based on nearby landmark

• outcrop-level geographic resolution

When: Commentry Shales Formation, Gzhelian (303.7 - 298.9 Ma)

• Stephanian

• group of beds-level stratigraphic resolution

Environment/lithology: lacustrine deltaic; lithified mudstone

• Fossiliferous layers are of fresh water origin and are allochthonous, apparently deposited by streams in delta-like, detritic sediments along the shore of a lake. Dextral strike-slip transtension in an intermontane setting following the Variscan orogeny.
• "The rock in which the insects occur is a very fine grained mudstone, which may well have accumulated by the deposition of fine sediment in enclosed or lake-like waters." Bolton, 1917

Size class: macrofossils

Preservation: mold/impression
