The ammonoids from the Grès du Kahla supérieur of Timimoun (Middle-early Late Tournaisian; Gourara, Algeria)
Abstract. The ammonoids from two very prolific horizons in the upper Kahla Sandstone (Tournaisian, Early Carboniferous) of Timimoun (Gourara, Algeria) are described monographically. Nine new ammonoid species are introduced: Imitoceras altilobatum n. sp., Triimitoceras amplisellatum n. sp., Kazakhstania inequalis n. sp., Acrocanites imperfectus n. sp., Xinjiangites scalaris n. sp., and Becanites canalifer n. sp. from the North African Kazakhstania-Acrocanites Assemblage as well as Acrocanites recurvus n. sp., Becanites singularis n. sp., and Becanites inflateralis n. sp. from the Pericyclus-Progoniatites Assemblage. The first of these is one of the most diverse ammonoid faunas known from this time interval.
