The ammonoids from the Early Carboniferous (Mississippian) Dalle à Merocanites of Timimoun (Gourara, Algeria) are described. The following new ammonoid taxa are introduced: subfamily Hammatocyclinae n. subfam., Hammatocyclus pollex n. sp., Hammatocyclus corrugatus n. sp., Neopericyclus arenosus n. sp., Ammonellipsites pareyni n. sp., Ammonellipsites menchikoffi n. sp., Ammonellipsites conradae n. sp., Muensteroceras fabrei n. sp., Eurites commutatus n. sp., Eurites pondus n. sp., subfamily Trimorphoceratinae n. subfam., Trimorphoceras n. gen., Trimorphoceras crassilens n. sp., Trimorphoceras absolutum n. sp., Trimorphoceras molestum n. sp., Obturgites n. gen., Obturgites polysarcus n. sp., Obturgites oligosarcus n. sp., Dzhaprakoceras dzhazairense n. sp., and Merocanites merocanites n. sp. These species occur in one very prolific horizon and can be attributed to the North African Ammonellipsites-Merocanites Assemblage (Fascipericyclus-Ammonellipsites Genus Zone; Late Tournaisian to Early Viséan). They represent one of the most diverse ammonoid faunas known from this time interval. Source

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. © 2010 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim. Source


Four ammonoid species are described from the Early Carboniferous (Mississippian) Iridet Formation of the Ahnet and Mouydir (Central Sahara, Algeria); three of which are new: Eurites temertassetensis n. sp., Trimorphoceras teguentourense n. sp., and Trimorphoceras azzelmattiense n. sp. The species can be attributed to the North African Ammonellipsites-Merocanites Assemblage (Fascipericyclus-Ammonellipsites Genus Zone; Late Tournaisian to Early Viséan). Additionally, the two new species Ammonellipsites sguilmensis n. sp. and Muensteroceras beniabbesense n. sp. are described from the time equivalent Hassi Sguilma Formation of the Saoura Valley (north-western Algeria). © 2010 WILEY-VCH Verlag GmbH & Co.

Twenty-seven ammonoid species are described from the Argiles de Timimoun of Timimoun (Gourara, Algeria). The following taxa are newly described: Rhnetites n. gen., Rhnetites rhnetensis n. sp., Rhnetites ouladallalensis n. sp., Parahammatocyclus mutaris n. sp., Bollandoceras nitens n. sp., Bollandoceras subangulare n. sp., Bollandoceras politum n. sp., Bollandoceras aridum n. sp., Bollandoceras zuhara n. sp., ollandoceras mirrih n. sp., Benimehlalites n. gen., Benimehlalites benimehlalensis n. sp., Benimehlalites belkassemensis n. sp., Benimehlalites brinkmanni n. sp., Pachybollandoceras n. gen., Pachybollandoceras intraevolutum n. sp., Pachybollandoceras repens n. sp., Bollanditinae n. subfam., Gourarites n. gen., Gourarites hagaraswad n. sp., Gourarites hagarkarim n. sp., Gourarites mustari n. sp., Gourarites zuhal n. sp., Semibollandites n. gen., Semibollandites kamil n. sp., Semibollandites pauculus n. sp., Semibollandites qawiy n. sp., Timimounia n. gen., Timimounia timimounensis n. sp., Timimounia lunula n. sp., Daaitidae n. fam., Daaites n. gen., Daaites daaensis n. sp., Dimorphoceras lanceolobatum n. sp., Nomismoceras salim n. sp., and Nomismoceras waltoni n. sp. The species occur in three successive horizons and can be attributed to the Bollandites-Bollandoceras Genus Zone (Early and Middle Viséan). They represent the most diverse ammonoid fauna known from this time interval. © 2010 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim. Source

Mimimitoceras is the most abundant late Famennian goniatite genus in the Anti-Atlas of Morocco and the Saoura Valley of Algeria. Based on conch morphology, conch ontogeny, suture line and ornament, six new species can be separated, which occur in three successive rock intervals. The new species M. carnatum, M. comtum, M. endocuboide, M. taourirtense, M. alidrisii and M. ibnishaqi are compared with time equivalent Central European species. © 2015 E.
