Late Givetian ammonoids from Oberberge (Middle Devonian; Rhenish Mountains)

Bockwinkel, Jürgen; Korn, Dieter


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.
