Palaeocupressinoxylon Uniseriale N. Gen. N. Sp., a Gymnospermous Wood from the Upper Permian of Central Taodonggou, Southern Bogda Mountains, Northwestern China
A silicified wood, Palaeocupressinoxylon uniseriale n. gen. n. sp., is described from the upper Permian of the Central Taodonggou section, Turpan—Hami Basin, Xinjiang Uygur Autonomous Region, northwestern China. Multidisciplinary data including U—Pb ID—TIMS zircon dating, vertebrate and invertebrate biostratigraphic, and cyclostratigraphic correlation from current and previous studies indicate that the fossil bearing interval is Wuchiapingian (late Permian) in age. The pycnoxylic wood consists of thick-walled tracheids and parenchymatous rays. It is characterized by separated uniseriate radial tracheidal pits, uniseriate ray cells, and cupressoid cross-field pitting. The absence of growth rings in the wood, together with the occurrence of Argillisols, Gleysols, and Histosols above and below the fossil interval, suggests that a stable landscape and a perennially humid climate prevailed in the Taodonggou area during the Wuchiapingian.
