Schellwienia arctica [Fusulinidae] from the Carboniferous-?Permian strata of the Treskelodden Formation, south Spitsbergen

Le résumé fourni par la source

The fusulinid foraminifers of Schellwienia arctica (Schellwien, 1908) have been investigated from Polakkfjellet Mt., south Spitsbergen, and used as biostratigraphic marker for the latest Carboniferous-?earliest Permian strata of the Treskelodden Formation. A se− ries of thin sections enable to investigate the internal structure and growth pattern of indi− vidual specimens. The observed variation of growth suggests dynamic environmental con− ditions at the investigated location and most likely over one−year long life span of this foraminifer.
