Mariposas Fmn, submember d4b-gamma, Nogueras area, Aragon, Spain (Devonian of Spain)

Where: Aragon, Spain (41.1° N, 1.1° W: paleocoordinates 44.6° S, 34.1° E)

• coordinate based on nearby landmark

• local area-level geographic resolution

When: d4b Member (Mariposas Formation), Late/Upper Emsian (402.5 - 391.9 Ma)

• submember d4b-gamma. Lower part of Upper Emsian.

• member-level stratigraphic resolution

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

• "In submember d4b-gamma (11m) a number of greyish marl beds are intercalated into the [greenish gray] shales. Bioturbation occurs. The calcareous contents are largely due to tiny crinoid remains, but dacryoconarids...are also essential."
