The Pliensbachian takes its name from the hamlet of
Pliensbach in the community of
Zell unter Aichelberg in the
Swabian Alb, some 30 km east of
Stuttgart in
Germany. The name was introduced into scientific literature by German palaeontologist
Albert Oppel in 1858. The base of the Pliensbachian is at the first appearances of the ammonite species
Bifericeras donovani and
genera Apoderoceras and
Gleviceras. The Wine Haven profile near
Robin Hood's Bay (
Yorkshire,
England) has been appointed as global reference profile for the base (
GSSP). The top of the Pliensbachian (the base of the Toarcian Stage) is at the first appearance of ammonite genus
Eodactylites.
Biostratigraphy , France The Pliensbachian contains five ammonite
biozones in the
boreal domain: • zone of
Pleuroceras spinatum • zone of
Amaltheus margaritatus • zone of
Prodactylioceras davoei • zone of
Tragophylloceras ibex • zone of
Uptonia jamesoni In the
Tethys domain, the Pliensbachian contains six biozones: • zone of
Emaciaticeras emaciatum • zone of
Arieticeras algovianum • zone of
Fuciniceras lavinianum • zone of
Prodactylioceras davoei • zone of
Tragophylloceras ibex • zone of
Uptonia jamesoni == References ==
