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.

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.

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.

Members of the genera Archoceras and Beloceras are very rare representatives in the ammonoid assemblage from the Frasnian (Late Devonian) Büdesheim Shales. These two genera occupy a position at the margins of the morphological spectrum within the fauna; Archoceras is interpreted as a paedomorphic form characterised by a reduction in morphological complexity in conch shape and suture line, while Beloceras is characterised by an increasing complexity in conch shape and suture line. © 2013 E.

Prionoceras is the most important middle 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, nine new species can be separated, which occur in four successive rock intervals. Prionoceras can thus be used as a tool for an independent goniatite-based biozonation, best shown for sections in the Anti-Atlas of Morocco. The new species P. vetus, P. lamellosum, P. takhbtitense, P. subtum, P. jeranense, P. lentis, P. mrakibense, P. ouarouroutense, P. tetrans and P. triens are compared with the time-equivalent Central European species P. divisum and P. frechi. With the addition of these ten new species, the Anti-Atlas of Morocco shows the highest species richness for the genus. © 2014 E. Schweizerbart'sche Verlagsbuchhandlung, Stuttgart, Germany.

A small late Givetian (Middle Devonian) ammonoid assemblage from Oberberge near Schwelm is described. The co-occurrence of the genera Mzerrebites, Pharciceras, Epitornoceras and Tornoceras indicates reference to the base of the Pharciceras genus zone. Mzerrebites bifurcatus and Mzerrebites schwelmensis are revised with the proposal of neotypes; the new species Pharciceras oberbergense n. sp. and Tornoceras wunderlichi n. sp. are described. ©2015 E.
