Neovermilia gundstrupensis sp. nov. (Polychaeta, Serpulidae) from the Selandian (middle Paleocene) of Fyn, Denmark

Tubes of a new serpulid species, Neovermilia gundstrupensis sp. nov., from the lower part Kerteminde Marl Formation (Selandian, middle Paleocene) Gundstrup gravel pit, Fyn, Denmark, represent first serpulids this group Selandian Denmark. Within long-ranging genus (Oxfordian to Recent), finds extend last recorded occurrence an informal sub-group closely related upper Danian Selandian. is characterized by tube increasing only slowly in diameter reaching up approximately 5 mm and possessing small, often densely spaced annular striae occasionally merging into weakly but never strongly developed peristomes. Almost all specimens found so far are attached siliceous sponges Ventriculites. The morphology species microstructure wall, as well its palaeoecology discussed.
