4721EC2A4466FFC838B73A7FFEC7286A.taxon	discussion	DISCUSSION ffle specimens are assigned to? P. decorata, due to their characteristic fine perpendicular tube ornamentation.? Pyrgopolon decorata is a serpulid because of the chevron-shaped growth lamellae, and we tentatively ascribe this species to the genus Pyrgopolon because of its relatively thick walled and large tubes.? Pyrgopolon decorata differs from? P. aff. nodulosum by the presence of fine regular perpendicular ornamentation.? Pyrgopolon decorata differs from? Pyrgopolon sp. A in having fine regular perpendicular ornamentation and ampullacea-type peristomes.	en	Vinn, Olev, Hryniewicz, Krzysztof, Little, Crispin T. S., Nakrem, Hans A.

4721EC2A4466FFC838B73A7FFEC7286A.taxon	discussion	DISCUSSION ffle specimens presumably belong to Dentalium nodulosum Lundgren, 1883, because they have a similar general appearance and lack of fine perpendicular ornamentation. Dentalium nodulosum is a serpulid, not a scaphopod, because of the chevronshaped growth lamellae. ffle species is tentatively assigned to the genus Pyrgopolon because of the relatively large tubes.	en	Vinn, Olev, Hryniewicz, Krzysztof, Little, Crispin T.
