Where: Tatawin, Tunisia (32.9° N, 10.3° E: paleocoordinates 16.1° N, 10.9° E)

• coordinate based on nearby landmark

• outcrop-level geographic resolution

When: Continental Intercalaire Formation, Barremian to Barremian (129.4 - 100.5 Ma)

• Beds are not easily dated but studies in the last few years agree that beds exposed in Tunisia are likely Barremian–Albian. See Fanti et al. 2012; Hamed et al. 2014; Fanti et al. 2016; Holwerda 2020
