The central reef facies (widespread in the Kalbling reef and Schildmauer reef) is defined by an autochthonous reef-framework (composed of corals,
calcisponges, algae, and many epizoans), which interfingers with quantitatively prevailing reef debris. The reef-framework consists of various biocoenoses (high growing corals, low growing corals, calcisponges, hydrozoa and bryozoa,
solenoporacean algae).
