It forms a biostrome that is 5 m height and 1000 m long. The bottom 1.5 m consists of small lenses of crowding Thamnoporida. Some of lenses are 10 m long, and they rise up to 20-40 cm in the center. The upper 1.5 m of the biostrome consists of lenses full of Thamnoporida as well. In the middle part of the biostrome, there are massive colonies of Stromatoporoidea and Favositida with Thamnoporoida in the interstices. The following taxa were also found in the biostrome: brachiopods, single trilobites, solitary and fragments of massive colonies of Rugose, Crinoidea and Algae.
