A critical restudy of the brachiopod Flabellothyris oranensis from Si Slimane ben Moussa in northwestern Algeria, and various places in the eastern High Atlas and Middle Atlas mountains of Morocco, with respect to its vertical stratigraphic range and its relationships to associated fauna indicates Dogger (middle Jurassic) age--perhaps upper or terminal Bajocian, or lower Bathonian. The species is redescribed in accordance with the material at hand. Attention is called to the similarity between F. oranensis and F. dichotoma of the Bathonian (upper middle Jurassic) and Callovian (lowermost upper Jurassic) of India and Madagascar.
