Three new species of Middle Devonian otarionine trilobites are described: Cyphaspis walteri sp. nov. from the Bou Dib Formation in Morocco, Cyphaspis rommersheimensis sp. nov. from the Freilingen Formation in Germany, and Cyphaspis heissae sp. nov. from the Ahbach Formation in Germany. Cyphaspis cf. heissae sp. nov. is described from the Hanonet Fo...
Proetid trilobites are described from Middle Devonian strata in the Dinant Synclinorium, Belgium. Astycoryphe arduinnae sp. nov., Dohmiella cf. dohmi (richter & richter), Longiproetus cf. tenuimargo (richter), Gerastos sp. C, and Quadratoproetus sp. A are recorded from the Jemelle Formation (Eifelian) in Boutonville. These taxa provide the first co...
Scutellum decipulum n. sp. and Scutellum protrusifrons n. sp. are described from the Frasnian Moulin Liénaux and Grands Breux Formations respectively in the Couvin area. Until recently, scutelluids from this time interval in Belgium were commonly identified as the Polish species Scutellum costatum Pusch but these assignments are now revised. Scutel...
Members of Ceratarges Gürich are known from Devonian strata in various countries but they have not yet been formally described from Morocco. Ceratarges ziregensis sp. nov., Ceratarges koumalii sp. nov. and Ceratarges aries sp. nov. are herein described from the El Otfal Formation (Eifelian) in Morocco on the basis of complete specimens. Supplementa...
Trilobites have long been known to occur in Belgium in strata of Ordovician, Devonian and Carboniferous age. Devonian rocks are the most widespread of Palaeozoic outcrops there, yet the trilobites that they yield are the least known by far. Records (usually lists of species without illustrations or type numbers) frequented the old literature until...
Proetids are common trilobites in the Middle Devonian of the Ardennes and Eifel. They are known from ample material and so provide an excellent basis for taxonomic and biostratigraphic studies. Seven new species are recorded from the Ardennes, Belgium (Gerastos arcus n. sp., Gerastos couvinensis n. sp., Gerastos snellingsi n. sp., Astycoryphe exili...
Trilobites of "Rhenish" and "Bohemian" type are recorded from the Longlier Formation (Pragian to possibly Lower Emsian) at several localities in the Neufchâteau Synclinorium (southeast Belgium) on the basis of material currently kept at the Royal Belgian Institute of Natural Sciences. The occurrences of Belenopyge sp. (= Lobopyge PŘIBYL & ERBEN), P...
Two trilobites, Pedinopariops hoelleri n. sp. (Phacopidae) and Tropidocoryphe bassei n. sp. (Proetidae), are recorded from middle Eifelian strata at the "Trilobitenfelder" near the village of Gees, Germany. Lithology of the Gees Subformation (Ahrdorf Formation) at Gees is briefly elucidated. The holotype of Tropidocoryphe barroisi (MAILLIEUX) from...
New data are presented on trilobites of the family Proetidae (subfamilies Proetinae, Dechenellinae, Cornuproetinae) from the Devonian of the Ardennes Massif and the Eifel Hills (Rhenohercynian zone). Preliminary stratigraphic distributions of the Proetidae from the southern border of the Dinant Synclinorium are introduced. Eight taxa are recorded,...
Specimens of Cyphaspis Burmeister are recorded from Eifelian and Frasnian strata in Belgium as well as from Eifelian strata in Germany, and are assigned to six taxa. Scant information has hitherto been available onCyphaspis from the Ardennes. From this region Cyphaspis unguloides belgica n. ssp., Cyphaspis sp. B, Cyphaspis sp. C, and Cyphaspis sp....
