New data on Late Devonian and Early Carboniferous brachiopods from NW Sahara: Morocco, Algeria

The new systematic data of this paper concern 60 taxa collected in the late Famennian and Early Tournaisian deposits from the southern Anti-Atlas, Ma'der-Tafilalt regions (Morocco) and Timimoun area (Algeria). The deposits yield representatives from: the Strophomenids (Leptagonia, Schuchertella), the Productids (Hamlingella, Whidbornella, Kahlella, Acanthatia (?), Productina, Mesoplica, Semiproductus, Spinocarinifera, Ericiatia), the Rhynchonellids (Centrorhynchus, Macropotamorhynchus, Hemiplethorhynchys (?), Paurogastroderhynchus, Megalopterorhynchus, Shumardella, Gastrodetoechia), and the Spiriferuds (Cystospirifer, Sphenospira, Dichospirifer, Prospira, Parallelora, Unispirifer, Eobrachythyris, Voiseyella, Hollardospirifer n. gen., Eochoristites, Eomartiniopsis Tylothyris, Syringothyris). The occurrence of these brachiopods, their systematic analysis, stratigraphic position, and their relatioships could be very useful for improving correlations between various neritic sedimentary series near the Devonian/Carboniferous boundary.
