Abstract

Conodont faunas are described from Triassic sections of Svalbard, and their occurrences are locally correlated with established ammonoid zones. With a synthesis of previous conodont-based publications the current work presents a taxonomically up-to-date compilation of conodont data for the Triassic of Svalbard, and is herein used to construct a conodont-based biochronology indexed to the current lithostratigraphic nomenclature. Twenty-eight taxa spanning the earliest Griesbachian – earliest Carnian are presented in a range chart. The examined conodont faunas are correlated with well established conodont zonations of the Canadian Arctic, and in turn also form the basis for regional correlations.
