本文系统描述了产自我国新疆塔里木盆地晚奥陶世晚期的管状体 ,包括 2属 8种 ,其中一个新种。通过对比研究 ,本管状体组合与 Burgess和 Edwards( 1991)的下组合相当。根据本组合的研究 ,对 Burgess和 Edwards的组合进行了补充 ,其组合由不同类型的光壁管、低分异度的内壁加厚管组成 ,未见外壁加厚管和丝状体 ,组合的时代从中奥陶世到早志留世 (晚 L landovery)。根据植物学的对比研究 ,管状体主要产自 Nem atophytales L ang。
This paper systematically describes the Late Ordovician Tuber from the Tarim Basin in China, including 8 species of 2 genera and one new species. Through comparative studies, this tubular combination is comparable to that of Burgess and Edwards (1991). The combination of Burgess and Edwards is complemented by a combination of Burgess and Edwards combinations consisting of different types of light-walled tubes, low-profile inner-wall thickened tubes, no outer thickened tubes and filaments, and a combination of Era from the Middle Ages to early Zhiyu (late L landovery). According to a botany comparative study, the tubular body is mainly produced from Nem atophytales L ang.
