The ammonoids from the Grès du Kahla supérieur of Timimoun (Middle-early Late Tournaisian; Gourara, Algeria)
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: <i>Imitoceras altilobatum</i> n. sp., <i>Triimitoceras amplisellatum...

Summary: | 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: <i>Imitoceras altilobatum</i> n. sp., <i>Triimitoceras amplisellatum</i> n. sp., <i>Kazakhstania inequalis</i> n. sp., <i>Acrocanites imperfectus</i> n. sp., <i>Xinjiangites scalaris</i> n. sp., and <i>Becanites canalifer</i> n. sp. from the North African <i>Kazakhstania-Acrocanites</i> Assemblage as well as <i>Acrocanites recurvus</i> n. sp., <i>Becanites singularis</i> n. sp., and <i>Becanites inflateralis</i> n. sp. from the <i>Pericyclus-Progoniatites</i> Assemblage. The first of these is one of the most diverse ammonoid faunas known from this time interval.
