2280-III-A-1/2, Tarut Formation, Ash Shati area, N. flank of Murzuk Basin (Devonian of Libya)

Where: Libya (27.7° N, 14.7° E: paleocoordinates 40.6° S, 24.1° E)

• coordinate estimated from map

• outcrop-level geographic resolution

When: Tarut Formation, Famennian (372.2 - 358.9 Ma)

• "The age of the Tarut Fm. is only poorly documented by fossils...[pollen and conodonts discussed]"

• bed-level stratigraphic resolution

Environment/lithology: marine; ferruginous claystone and ferruginous siltstone

• "Extremely shallow-water environment is evident from the fact that truncated stems of lycophytes have been found standing upright, i.e. in-situ, in the ferruginous oolite (e.g., west of Quttah)."
• Formation as a whole: "The lower and middle parts...are prevalently...claystone with subordinate interbeds of siltstone. A prominent sst. layer, the so-called 'Bivalves key bed' is developed amidst the claystones. The upper part is mostly...ferruginous oolites and sst. which are connected with mutual lateral transitions. The total thickness of the Fm. varies between 45 and 10 m."
