... of the Etendeka igneous province across much of the basin at 132 ± 1 Ma. The lavas “drowned” the dunes and, in doing so, preserved bed forms with heights and wavelengths of up to 100 m and 1.3 km, respectively. Subsequent erosion has resulted in the exposure of these bed forms and provides a rare opportunity...

... with the potential to ‘fossilize’ these continental environments. The Paraná–Etendeka Flood Basalt Province is one of the largest igneous provinces, covering an area of 1.3 × 10 6 km 2 ( Milner et al. 1995). The present‐day preserved extent of the province is shown in Fig. 1, where it has been placed in its...
