Chouigui section 1 (Triassic of Tunisia)

Where: Banzart, Tunisia (36.9° N, 9.8° E: paleocoordinates 0.1° N, 16.9° E)

• coordinate based on nearby landmark

• small collection-level geographic resolution

When: Ladinian (242.0 - 237.0 Ma)

• Successions have been preserved without statrigraphic disruptions along 'parts of continuous cross-sections' included within the chaotic, evaporite-dominated, formations forming large structures previously interpreted as Triassic diapirs. Triassic series are reconstructed from four principal sections, beginnings at the Lower Ladinian, exceptionally evidenced by ammonites, and reaches up to the Rhaetian dated by benthic foraminifera.

• group of beds-level stratigraphic resolution

Environment/lithology: marine; sandstone

• Thin sanstones, multicoloured clays and particularly yellow shelly dolomites containing a rich fossil assemblage

Size class: macrofossils
