Abstract
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., Bollandoceras 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.
