[b]The succession of ammonites of the genus [i]Amoeboceras [/i]in the Upper Oxfordian – Kimmeridgian of the Nordvik section in northern Siberia[/b]
Journal Title: Volumina Jurassica - Year 2009, Vol 7, Issue 1
Abstract
A collection of ammonites of the genus [i]Amoeboceras [/i]located carefully in the section of Nordvik Peninsulain northern Siberia has enabled recognition of the standard Boreal ammonite zones of the Upper Oxfordian and Kimmeridgian. The recognition of the standard [i]Amoeboceras [/i]zones, well known in NW Europe and the Barents Sea area, in northern Siberia indicates the uniform character of the Late Oxfordian and immeridgian ammonite faunas across the whole Boreal Province. Some comments on the occurrence of Boreal oppeliids of the genus Suboxydiscites in the studied section are also given.
