The paper is a report on the discovery of tubes of a fossilised cave serpulid in a roofless cave in the quarry near village Crnotice. The site and shape of the fossilised tubes are described. The animals lived attached to the scallops in the wall of the water filled passage. The passage was later filled with clay deposits, followed by a layer of sinter several metres thick. The roof of the passage has been removed by karst denudation and the sinter now reaches to the surface. Fragments of tubes of animals of various sizes have been preserved, attached to the rock wall; those tubes that grew at a right angle to the wall have broken off but been preserved in the sediment. In terms of their dimension and shape the tubes remind one of the tubes of the more recent cave serpulid Marifugia cavatica Absolon and Hrabe. The dating of the nearby sediments by palaeomagnetic method show that the minimum age of the serpulids is 1.7 Ma, but greater age is more probable. |
