贵州台江早寒武世台江生物群

THE EARLY CAMBRIAN TAIJIANG BIOTA OF TAIJIANG, GUIZHOU, PRC

台江八郎下、中寒武统界线之下的灰绿色粉砂质泥岩中存在一个布尔吉斯页岩型生物群 ,即台江生物群。现已发现的台江生物群含 8个门类 4 0多个属的生物化石。其中三叶虫特多 ,其次为刺胞动物、“蠕虫动物”、海绵动物等。非三叶虫节肢动物、软躯体化石很少。这一生物群形成于浅海内陆棚环境。

Numerous specimens of a large number of fossil taxa have been collected from the lower part of the Kaili Formation (Lower Cambrian) in the Balang section near the town of Taijiang, Guizhou Province, PRC. These fossils represent a distinct community, called the Taijiang biota (Zhao et al., 1998)
