Abstract: | The article reports the finding of some late Paleocene (Thanetian) species of Phaeodarian Radiolaria in phosphorite concretions occurring in the Holmehus Formation of Denmark. These species are associated with a rich assemblage of diatoms and sparse spherical radiolarians. Phaeodarians are very well-preserved in celestobarite (BaSrSO4) and consist of representatives of the families Challengeridae (Challengerebium triangulovum nov. sp. and Challengerebium sp.) and particularly Medusettidae (Medusetta danica nov. sp. and M. densicostata nov. sp.), which are the most frequent. A new genus of medusettid phaeodarians (Pseudochallengeranium nov. gen.) is also described. |
