Abstract

New datings of calcareous sandstone lenses and olistolites exposed in the middle part of the siliciclastic Mouchenkour Formation indicate a Late Asbian/Early Brigantian age (Cfm7/Cfm8 Moroccan biozone). The calcareous microfossil assemblages are characterized by the problematic algae Ungdarella, Fasciella and Koninckopora and foraminifers Archaediscus (concavus stage), Pseudoendothyra and Eostaffella. An Asbian/Brigantian palaeogeography based on the depositional environments is reconstructed from northwest to southeast, from the Tizra to the Mouchenkour areas. The units, although in tectonic contacts, nearly preserve their initial location and relations. To cite this article: D. Vachard et al., C. R. Palevol 5 (2006). © 2006 Académie des sciences.
