云南保山、施甸下石炭统可建立三个腕足动物组合,自下而上为:1.Unispirifer tornacensis-Marginatia burlingtonensis组合,大致可与英国Courceyan对比,时代为杜内中、晚期;2.Grandispirifer dazhaimenensis sp.nov.-Balackhonia yunnanensis组合,Grandispirifer大量出现于石花洞组底部,地理分布广泛,层位稳定,可作为杜内与维宪阶的分界标志。大致与英国的Arundian-Holkerian对比,时代为维宪早、中期;3.Delepinea comoides-Megachonetes papilionacea组合,大致与英国Asbian-Brigantian对比,时代为维宪晚期。
Three Brachiopods animal assemblages can be established in the Lower Carboniferous of Baoshan, Shidian, Yunnan. Bottom-up: 1.Unispirifer tornacensis-Marginatia burlingtonensis, which can be roughly compared with Courceyan in England and Middle and Late Durand; 2. Grandispirifer dazhaimenensis Sp.nov.-Balackhonia yunnanensis assemblage, Grandispirifer appeared in large numbers at the bottom of Shihuadong Formation, with wide geographical distribution and stable horizon, which can be used as the demarcation mark of Dune and Vysehrad. Roughly compared with the British Arundian-Holkerian, the era of Vixen morning and mid-term; 3.Delepinea comoides-Megachonetes papilionacea combination, roughly compared with the British Asbian-Brigantian, the era of the late Uighur.
