The eastern Anti-Atlas is famous for its 1.1. stratigraphy internationally celebrated geological heritage The Devonian was the first system in which (e.g., EL HASSANI et al. 2017), but, as presented all chronostratigraphic units (series and stages) in this volume, there are equally important and were formally defined, producing a stable time fossil-rich localities in the Western Meseta and frame work for detailed international and Middle Atlas basement. interdisciplinary correlation (e.g., BECKER et al. 2012, 2020). This also applies to the main 1.2.

Fossiliferous Devonian strata are mainly exposed in the eastern Jebilet (e.g., Bou Marhara and Smaha). They correspond to Lower Devonian allochthonous or para-autochthonous series (HUVELIN 1977; TAHIRI 1982). The litho- and biofacies shares similarities with the Skoura region, especially in the presence of griotte limestones with rich upper Emsian goniatites (anarcestids), and with East Central Morocco (Azrou-Khenifra zone). We logged and
