Tellian bed 1 (Triassic of Tunisia)

Where: Banzart, Tunisia (37.3° N, 9.9° E: paleocoordinates 0.1° N, 14.5° E)

• coordinate based on nearby landmark

• small collection-level geographic resolution

When: Bechateur Formation, Ladinian (242.0 - 237.0 Ma)

• 30m of limestone have been assigned to Ladinian-Carnian by Salaj and Bajanid, 1972. They overthrust Ypresian limestones towards the SW by may have been stratigraphically superposed to siliciclastics (Anisian ?), presently not visible. These Triassic limestones (herein called 'Bechateur Formation'), alternatively microrhythmic, are interrupted by three successive key-beds

• group of beds-level stratigraphic resolution

Environment/lithology: marine; limestone

• Calcareous tempestite storm deposit, ravining the inderlying limestone.

Size class: macrofossils
