Coral fauna is moderately diversified (only 14 genera) associated with coralline algae and larger foraminifers (mainly dyscocyclinids). Tue sequence is represented by three main fades (from the bottom upwards): 
1 - Grainstone-packstone facies (ca. 15 m thick) rich in discocyclinids, nummulitids, scleractinian corals, and bryozoans. Large subglobose coral colonies (Actinacis, Antiguastrea, Astrocoenia, Favites and Agathiphyllia) and sublaminar and globose colonies of bryozoans are typically in life position. The displaced colonies are rare and typically bear no evidence of transport (bush-like colonies of e.g.,Actinacis seem to be only fallen down). Generally colonies preserved in situ are immersed in a bioclastic packstone that, with a sharp contact, passes to a grainstone wich disoriented discocyclinids. At the top of this fades present are also debris ßows with branching corals like Acropora, Stylophora and other large bioclasts. Abundant coralline algae and specimens of pectinids and other molluscs are also associated with this facies.
2 - Bioclastic limestone (rudstones and/or floatsrones) facies (ca. 4S m thick) rich in scleractinians and coraline algae. 
3 - Wackestone-mudstone facies (ca. 12 m chick) with planktonic foraminifers, in which are debris-flows composed mainly of larger foraminifers and broken coral colonies.
