Abstract

Four spicule-bearing chaetetid sponges are described from Upper Triassic (Norian) reef carbonates of the WesternTaurids (Antalya-Region, SW Turkey): Atrochaetetes alakirensisCuif & Fischer, Blastochaetetes dolomiticusBizzarini & Braga, Ptychochaetetes sp. and ?Bauneia sp.. Spicules are preserved as calcitic pseudomorphs. They are either short and thick or long and slender, corresponding to typical styles; oxes are rarely present in Atrochaetetes alakirensis. The styles are mainly embedded in the secondary rigid skeleton, but their rounded ends appear to be attached to the primary wall. In Blastochaetetes dolomiticus and ?Bauneia sp. styles are also embedded in the primary wall. A comparison of these spicule-skeletons with those of other chaetetids, especially Paleozoic species, confirms the polyphyletic origin of the Taxon Chaetetida.
