Facies with large Bryozoa

This facies is characterised by the frequent presence of big colonies of arborescent bryozoans, unattached or fixed to small substrata. These bryozoans are mainly Pentapora fascialis, Smittina cervicornis, Reteporella spp., Myriapora truncata, Cellaria spp. Cheilostomatids, and also Cyclostomatids such as Hornera lichenoides and H. frondiculata. These species are also frequent on ill-lit rock faces and are then associated with the coralligenous biocenosis. Colonies of large bryozoans can form plurispecific aggregates and are often associated with concretions and nodules of calcified algae, sciaphilous soft algae like Kallymenia spathulata, Osmundaria volubilis, and big fixed invertebrates like the hydrozoans, the alcyonarians and simple ascidians.
