本文报道了一新属（Protosciadopityoxylon gen nov.）本文报道了辽宁省早白垩世木化石的一个新种：Protosciadopityoxylonliaoningensegen.etsp.nov.，并将该属命名为木化石，认为它与现代木化石属Sciadopitys和木化石属Sciadopityoxylon关系密切。新属与原叶木属、原圆孔木属和异木属在不同地质时代有相似之处，但在交叉场孔蚀类型上有所区别。
A new genus (Protosciadopityoxylon gen nov.) of Early Cretaceous fossil wood reported in the present paper was discovered from Liaoning Province, China, and is named as a new species: Protosciadopityoxylon liaoningense gen. et sp. nov. It is described here and this generic name, adopted by the authors, is employed for fossil wood that is believed to be nearly related to the recent genus Sciadopitys and the fossil genus Sciadopityoxylon. The new genus bears some similarities to Protophyllocladoxylon, Protocircoporoxylon and Xenoxylon in different geological ages, but it differs from them in the types of crossfield pitting.
