在对Dobrzyca 2钻孔（西波美拉尼亚）的档案样本进行孢粉学研究时，发现了触手虫的有机残留物。到目前为止，触手类动物因其丰富的矿化壳而广为人知。另一方面，作为有机遗骸，它们直到2004年才被发现。该发现是目前在上泥盆统地层中发现的第二个此类发现。一些已知的触手类有机残骸的形状和形态与属于Nowakiida目和Stylionida目的爪虫的胚胎和幼年形态相似。根据形态特征，确定了两个样品的年龄分别为Frasnian、RB和RD局部小孢子区。
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.
