伴随晚泥盆世弗拉期–法门期之交的Kellwasser和泥盆纪–石炭纪之交的Hangenberg生物灭绝事件, 泥盆纪的主要造礁动物层孔海绵消失、珊瑚多样性急剧减少, 之后的早石炭世是造礁珊瑚的关键复苏期。贵州雅水剖面下石炭统维宪阶上司组发育了丰富的原位珊瑚层, 即层状珊瑚礁, 依据有孔虫化石确定珊瑚层的时代为维宪晚期。上司组珊瑚层主要由丛状复体四射珊瑚组成, 多样性低, 可识别出2属2种: Siphonodendron pauciradiale 和Stylostrotion pentalaxoidea。其中, S. pauciradiale广泛分布于西欧和北非地区维宪晚期的珊瑚礁中, 而S. pentalaxoidea分布局限, 目前仅见于华南板块。雅水剖面维宪晚期全球广布的造礁珊瑚S. pauciradiale的出现, 指示华南地区珊瑚礁的复苏演化过程与全球具有一致性。

Accompanying the Late Devonian Frasnian-Famennian Kellwasser and the Devonian–Carboniferous Hangenberg mass extinction events, the main Devonian reef builders of stromatoporoid sponges and corals disappeared and dramatically declined, respectively. The subsequent Early Carboniferous is the critical recovery period for the reef-building corals. The Visean (Lower Carboniferous) Shangsi Formation at the Yashui section, Guizhou Province has yielded abundant coral autobiostromes (biostromal reefs). Based on foraminiferal biostratigraphy, the age of these coral biostromes was proposed to be late Visean. The Shangsi coral biostromes mainly consist of colonial rugose corals with low diversity. Two species belonging to two genera are identified: Siphonodendron pauciradiale and Stylostrotion pentalaxoidea. Siphonodendron pauciradiale is widely distributed in the late Visean coral reefs in Western Europe and North Africa, while S. pentalaxoidea is limited locally in the South China Block. The occurrence of the cosmopolitan reef-building coral S. pauciradiale during the late Visean at the Yashui section indicates that the recovery and evolutionary process of the coral reefs in South China is consistent with that of the globe after the Late Devonian extinctions.
