摘要	A new Kasimovian cordaitalean fossil axis, Shanxioxylon yangquanense sp. nov., is described from the Pennsylvanian Benxi Formation of Yangquan City, Shanxi Province, North China. The axis is composed of the pith, primary xylem, secondary xylem, phloem and cortex. The pith is septate or hollow, heterogeneous, with parenchyma cells and spherical secretory cavities distributed at the periphery. Cauline bundles are endarch. Leaf traces are mesarch, mostly diverging from pith margin as single bundle. Double leaf traces are present occasionally. The secondary xylem is pycnoxylic, featured by dominantly araucarian uniseriate radial tracheid pits and cupressoid cross-field pitting. The fossil axis represents the third and oldest species of Shanxioxylon (Tian et Wang) Wang et al. from the upper Paleozoic of Cathaysia, indicating that this endemic cordaitalean genus had evolved by at least the Kasimovian in North China. Shanxioxylon yangquanense sp. nov. is proposed to have lived as an arborescent form in the clastic wetland of stream riparian zones under a perhumid climate based on its great morphological and anatomical similarities to Agathoxylon leei (Sze) Wang et Wan from the same fossil interval.
