Huesa Fmn, Segura-Huesa del Comun area, Aragon, Spain (Devonian of Spain)

Where: Aragon, Spain (41.0° N, 1.0° W: paleocoordinates 33.3° S, 19.6° E)

• coordinate based on nearby landmark

• local area-level geographic resolution

When: Huesa Formation, Frasnian (382.7 - 372.2 Ma)

• formation-level stratigraphic resolution

Environment/lithology: marine; micaceous shale and sandstone

• see lithology
• "very fine dark grey to black shales with or without mica. In constantly changing amounts, coarser mica, silt, and fine sand may be diffusely present or may have been brought in to form well defined beds...Dark quartzites intercalate in black shales and seem to be turbitides...The sediments evoke the impression of an environment within a rapidly sinking trought with level bottom (uninterrupted beds)..."
