广西宁明第三纪—被子植物果实
具5片宿存花被的果实化石在北半球第三纪地层中常有发现。此类化石的分类位置一直存有争议,曾被鉴定为旋花科(Convolvulaceae)飞蛾藤属(Porana)、漆树科(Anacarabiaceae)阿斯羌属(Astron...

A new early cyprinin from Oligocene of South China被引量:6
2011年
Here we describe tHuashancyprinus robustispinus, gen. et sp. nov, a fossil cyprinin fish from the Oligocene of Ningming Ba- sin, Guangxi, South China. It differs from all other cyprinin fishes in the following apomorphic characters: extremely robust last unbranched dorsal and anal fin rays with very fine serrations along posterior edge, the crowns of pharyngeal teeth A2 and A3 with a number of deep grooves on the lateral wall, rather large A3, and relatively deep infraorbital 2. Among the members of the Tribe Cyprinini sensu stricto, it mostly resembles the extant genus Cyprinus, particularly to species Cyprinus micristius and C. fuxianensis, which are restricted to Yunnan, southwestern China. The discovery of the cyprinin Huashancyprinus from southern China, along with the previously known late Eocene tCyprinus maomingensis, indicates an early branching of the Cyprininae (Cyprinidae) in this area.

广西宁明第三纪叶生真菌
叶生真菌化石的研究对于了解植物和真菌相互作用的历史、恢复和重建古生态具有重要意义。然而,国内相关的报道很少,迄今为止,仅有郑少林和张武(1986)报道过辽宁昌图和阜新下白垩统两种苏铁类植物的叶生真菌。在观察产自广西宁明盆...

Redescription of Cobitis longipectoralis Zhou, 1992 (Cypriniformes: Cobitidae) from late early Miocene of East China被引量:1
2010年
Here we revise a fossil cobitid species ■Cobitis longipectoralis Zhou, 1992, based mainly on a well-preserved specimen collected recently from the taxon’s type locality of the late early Miocene of Shanwang, Shandong Province, East China. The new specimen, along with those collected by Zhou, enables us to provide an emended diagnosis and more detailed description of the species by focusing on the characters such as the structures of the suborbital spine and the presence and shape of the lamina circularis at the base of the second pectoral fin ray in adult males, the presence of a frontoparietal fontanelle, and a quad- rate-metapterygoid fenestra, etc. The long pectoral fin, initially considered by Zhou as the most important character of the spe- cies, however, turns out to be not diagnostic for the species. ■Cobitis longipectoralis Zhou, 1992 is not only the most informative and best-preserved early cobitid fossil known thus far but also the only and earliest cobitid fossil from East Asia.
