Number of spcies unknown due to dolomitization

Reef flats/caps contain mainly light gray crystal grain dolomites and sparry calcarenite. Reef cores are mostly sponge reef dolomites with the framework filled up by bioclasts and sand cuttings and contain a low content of calcilutite. Reef bases are less dolomitized and largely bioclastic limestones with bioclasts dominated by metacrinus and foraminifera.

Original Interval (Lopingian) was changed belated (Xuesong Tian, Yue Wang). 

Coordinates, environment and subenvironment changed according to Tian-Wang 2021 (see 3th. paper attached)

Reef builders:
Frame-building and baffling organisms: hypercalcified sphinctozoan and inozoan sponges, sclerosponges, bryozoans, and hydrozoans. Binding organisms: Archaeolithoporella, Tubiphytes, Fenestella, and cyanobacteria.

Reef dwellers:
Echinoderms, ammonites, bivalves, brachiopods, gastropods, benthic foraminifera, calcareous algae, and single rugose corals

Rock type and reef-related depositional characteristic:
Fore-reef slope: spiculitic-calcispherical cherty wackestone with reef breccias
Reef core: sponge framestone and bafflestone, Archaeolithoporella and cyanobacteria bindstone, and sponge framestone with the encrusting Archaeolithoporella
Reef flat (reef crest): packstone with reef breccia. 
Reef base: crinoidal packstone to grainstone. 
Back-reef: bioclastic dolostone with calcareous algae, gastropods, and foraminifers.

Reef type: 
Metazoan reef at the shallow carbonate platform margin
