Valvasoria carniolica n.gen. n.sp., a Triassic Worm from Slovenia

Abstract

Carnian limestones exposed from Mojstrana to Triglav (the highestSlovenian mountain) are very important biostraligraphically, andespecially for the palaeogeographic interpretation of the Upper Triassic.Outcrops can be traced in the Vrata Valley extending in the narrow bell several kilometres in a nort h-eastward - eastward direction. A very quiet deposilional environment, with reducing conditions at the sea floorr, permited the preservation of soft-bodied animal. Valvasoria carniolica is a new genus and specics. It has a cylindrical body with an expanded anteriormost portion. The systematic position of Valvasoria is unknown, however it might be related to Nematoda or Sipunculida.
