چکیده

Triassic successions of the present-day Arctic contain abundant and diverse assemblages nonmarine palynomorphs that have provided important biostratigraphic information. Dinoflagellate cyst are biostratigraphically useful in marine intervals Upper Triassic. Based on published records, we present a compilation 78 last occurrences (LOs), first (FOs), some abundance events anticipated to correlation potential region. Palynological work has been carried out many areas, with extensive palynological research Norwegian Barents Sea Svalbard. An updated, recent zonation scheme exists for region, integrating previous schemes illustrating chronostratigraphic value palynology For Lower Middle Triassic, good ammonoid control ties zones scale. Independent is sparse, resolution lower so commonly only discipline available dating correlation.
