Permian sponges from brachiopod cherts at Hornsund, Spitsbergen
Fourteen species of sponges are identified from brachiopod cherts of the Kapp Starostin Formation at Hornsund area. The new genus Spitsbergenia, five new species, and one subspecies are established: Haplistion hadrum sp.n., H. elongatum acremonicum n. subsp., Chaunactis kaera sp.n., Ch. malkowskii sp.n., Sptisbergenia patella gen. et sp.n. Members of the gen us Haplistion predominate. The general appearance of the preserved sponges, often the lack of traces of attachment to the substratum, and the presence of papillae, suggest that the environmental conditions must have been quiet and stable.
Key words: Spongiae, taxonomy, Permian, Spitsbergen.
