The Ammonite Zones of the Boreal Volgian (Upper Jurassic) in East Greenland

John H. Callomon, Tove Birkelund


Detailed collecting in the Upper Jurassic of Milne Land, central East Greenland, has established a succession of 24 ammonite faunas spanning the Lower and much of the Middle Volgian, up to a non-sequence extending into the Valanginian of the Lower Cretaceous. For the chronostratigraphic classification of the seven Lower Volgian faunas the standard zonation of Britain is used unchanged. The 17 faunas of the Middle Volgian are regionally distinct and form the biostratigraphic basis for a new Boreal provincial standard scale of nine zones. Correlations with Britain, Siberia and the Russian Platform are discussed: there has been great progress in the last 30 years, but many problems remain. Six new ammonite species of the family Dorsoplanitidae are described: three of Dorsoplanites, two of Pavlovia and one of Epipallasiceras.
