摘要
在延边开山屯地区大蒜沟组地层中,发现的植物化石大部分在吉南—辽东地区太原组中所常见,具有明显的晚石炭世华夏植物群的色彩;动物化石也大多属石炭—二叠纪常见分子。将具有这种生物组合的大蒜沟组置于晚石炭世—早二叠世早期是合适的。
The plant fossils were discovered in the Dasuangou Formation strata, Kaishantun, Yanbian area, most of them are commonly discovered in the Taiyuan Formation, southern part of Jilin Province-eastern part of Liaoning Province, having an obvious characteristics of the late Carboniferous Cathaysian florizone; the most of the zoolites are also commonly discovered in the Carboniferous-Permian period. So, it is suitable for taking the Dashuangou Formation with this bioseries as the late Carboniferous-beginning of the early Permian.
