Abstract
Many previous studies have shown that the living calcifying Demospongiae build calcareous structures with clearly distinctive features. In all the cases, precise study of the biomineralization patterns enables us to recognize the taxonomic position of fossils at the family level. In the Carnian faunas from Dolomites (northern Italy), and also in the lower Norian from Turkey (Lycian Taurus), it is possible to identify several known species as Ceratoporellids. Some of them have been initially described as Hydrozoa, like the Triassic representatives of Atrochaetetes and Blastochaetetes genus: a new genus ( Blastoporella) is proposed for The triassic Ceratoporellids with perforated walls. But other types also occur among the reef-builder organisms, exhibiting strong architectural peculiarities like the complex wall structure of the Kemeria nov. gen. All these types provide evidences for the importance of the Ceratoporellids in the shallow-water faunas of the last Triassic period, in association with scleractinian Corals and Algae.
