Reef fabric comprises mainly explanate and in some cases conical Rankenella, encrusted by more or less distinctly laminated, generally non-skeletal stromatolites. Angulocellularia-type microbial mesoclots and Angulocellularia locally intergrades into Taninia. Stromatolites appear to encrust upper surfaces of Rankenella skeletons, as well as those of other bioclasts such as calciate brachiopods, hyoliths and molluscs.
