Organic remains of tentaculitids have been recovered during palynological research on archival samples from the
Dobrzyca 2 borehole (Western Pomerania). Until now tentaculitids are widely known from their abundant mineralised
shells. As organic remains, on the other hand, they have only been known since 2004. The present discovery is currently the second one of this kind found in Upper Devonian strata. The shape and morphology of some recognized tentaculitid organic remains are similar to embryonic and juvenile forms of dacryoconarids belonging to orders Nowakiida and Stylionida. Based on palynomorphs, the age of the two samples investigated has been established as Frasnian, RB and RD local miospore zones.
