Lower permian palaeoaplysinid bioherms and associated sediments from central Spitsbergen

Abstract

Bioherms found in the Lower Permian Tyrrellfjellet Member of Central Spitsbergen contain bindstones produced by the ?hydrozoan taxon Palaeoaplysina. We briefly describe the bioherms’stratigraphical and environmental setting and note their development on hardground surfaces. The association of these structures with bituminous limestones is interesting in view of the petroleum resources of similar buildups in the USSR.
