Abstract (German)

Zusammenfassung. Das unternamurische Goniatiten-Intervall E1 (= Zone des Tumulites pseudobilinguis) kann in Profilen im Rheinischen Schiefergebirge auf der Basis von Girtyoceraten in sieben Zonen untergliedert werden, von unten nach oben Edmooroceras pseudocoronula-Zone, Edmooroceras medusa-Zone, Sundernites horni-Zone, Tumulites angustus-Zone, Tumulites pseudobilinguis 1-Zone, Tumulites pseudobilinguis 2-Zone, and Tumulites pseudobilinguis 3-Zone. Seine Obergrenze gegen die E2-Zone ist gekennzeichnet durch das erste Auftreten von Eumorphoceras grassingtonense DUNHAM & STUBBLEPIELD 1944.

Abstract

In sections of the Rhenish Massif, the early Namurian E1 goniatite interval (= Zone of Tumulites pseudobilinguis) can be subdivided into seven goniatite zones on the basis of girtyoceratid ammonoids. These are from bottom to top Edmooroceras pseudocoronula Zone, Edmooroceras medusa Zone, Sundernites horni Zone, Tumulites angustus Zone, Tumitlites pseudobilinguis 1 Zone, Tumulites pseudobilinguis 2 Zone, and Tumulites pseudobilinguis 3 Zone. Its upper boundary with the E2 Zone is marked by the first occurrence of Eumorphoceras grassingtonense DUNHAM & STUBBLEFIELD 1944.
