摘要
1963年9月作者在安徽铜陵铜官山市东的上二迭统龙潭组内(图1),找到了一块很有意思的标本——Gigantopteris sp.植物化石与两个贝壳类动物化石保存在一起(图版I-1;图2)。它除了提供生物地层学资料外,还有着化石埋藏学和地质学上的意义,值得记述。
This paper is to describe and illustrate an interesting taphocoenosis of the fossil plant and shells recently found by the writer from the Lungt’an-zu of Upper Permian near the city of Tongling,South Anhui.The taphocoenosis is represented by a rhombic specimen of medium size composed of a pinnule of Gigantopteris sp.,which occupies the whole specimen,and two valves of fossil shells fixed in the middle and lower part of it.These two valves are internal moulds,and one of them is a right valve of the lamellibranch.For the time being,the writer named them A and B respectively.Shell A is behind shell B in the position figured in Plate I,fig.1 and text-fig.2.
