Where: Agadez, Niger (16.6° N, 7.3° E: paleocoordinates 7.9° N, 2.2° E)

• coordinate estimated from map

• outcrop-level geographic resolution

When: Tiourarén Formation (Irhazer Group), Late/Upper Jurassic (161.5 - 145.0 Ma)

• Previously considered Bathonian–Callovian, but theropod remains suggest a Late Jurassic age for the fossiliferous horizons of the Tacuarembó Formation (see Serrano-Martínez et al. 2015 and Soto et al. 2020).

• bed-level stratigraphic resolution

Environment/lithology: levee; claystone

Size class: macrofossils
