一个常见的石松属，Sigillaria Brongniart，在欧洲和北美的泥炭形成森林中最常被记录，但在中国很少被记录。尽管在中国的煤球中发现了矽孢菌，并将其作为成煤元素的证据，但它从未在泥炭形成环境中被记录为压缩/印痕。最近对内蒙古乌达地区太原组早二叠世原生泥炭植物群的研究表明，Sigillaria可能是中国泥炭植被的主要组成部分。Sigillaria是唯一作为泥炭/煤形成的主要贡献者的乔木石松。Sigillaria属是中国与欧洲和北美古生代低地植物区系的另一个共同元素，增强了古特提斯洋东部和西部热带沼泽植被之间的共同花卉方面。版权所有©2009 John Wiley & Sons， Ltd
A common lycopsid genus, Sigillaria Brongniart, has been recorded most frequently in peat‐forming forests in Europe and North America, but rarely in China. Although Sigillaria, in China, has been found in coal balls and used as evidence that it was a coal‐forming element, it has never been recorded as compression/impressions in peat‐forming settings. Recent investigation of an Early Permian autochthonous peat‐forming flora of the Taiyuan Formation near Wuda, Inner Mongolia, has provided evidence that Sigillaria could be a major element of peat‐forming vegetation in China. Sigillaria is the only arborescent lycopsid acting as a major contributor to peat/coal formation. The genus Sigillaria is another element that China has in common with the Palaeozoic low‐land floras of Europe and North America, enhancing the common floral aspects between the tropical swamp vegetations of the east and west regions of the Palaeotethys Ocean.
