本文根据宽中柱和密木型次生木质部的解剖结构，描述了采自中国北方呼尔泰煤田Guadalupian下石盒子组的一个银杏植物新分类群--Palaeoginkgoxylon zhoui gen. nov. etsp. nov.。新的木本树干的解剖结构类似于早期裸子植物的Eristophyton-Pitus类型和现代银杏。因此，新的树干被解释为代表的过渡阶段，银杏从早期的木本植物，自石炭纪以来的演变。(C)2010 Elsevier B. V.保留所有权利。
A new taxon of ginkgophyte affinity Palaeoginkgoxylon zhoui gen. nov. et sp. nov. is described from the Guadalupian Lower Shihhotse Formation of the Hulstai coalfield, Inner Mongolia Autonomous Region (Nei Mongol), northern China, on the basis of the anatomical structures of the broad eustele and pycnoxylic secondary xylem. The anatomical structure of the new woody tree trunk resembles both the early gymnosperms of Eristophyton-Pitus types and the modern Ginkgo. Therefore, the new tree trunk is interpreted as representing a transitional stage in the evolution of Ginkgo from early arborescent lignophytes since the Early Carboniferous. (C) 2010 Elsevier B.V.
