Non-pollen palynomorphs from the Devonian (Givetian/Frasnian) of south-central Poland

The first report of the Devonian non-pollen palynomorphs (NPP) from the Givetian/Frasnian of ­Poland reveals diverse assemblages that contain chitinozoans, scolecodonts, organic tentaculitoids, animal remains, phytoplankton, plant debris, nematophytes and fungi. Analysed material provided the first documentation of chitinozoans from this time interval in Poland and the world oldest occurrence of organic tentaculitoids. These palynomorphs hold significant palaeoenvironmental value. The differentiated palynomorph assemblage indicates a deposition in a shallow water-marine environment with high terrestrial input. The age of the analysed deposits was established as “Geminospora” extensa (Ex) Miospore Zone to Geminospora aurita (Aur) Miospore Zone (conodont zones hemiansatus to lower falsiovalis).
