安徽贵池县梅埂地区早第三纪叶肢介化石

EOGENE FOSSIL CONCHOSTRACA, MEIGENG, GUICHI, ANHUI

安徽贵池县梅埂地区,属长江南岸铜陵盆地的西段,此区分布有红色陆相碎屑岩地层,以往地质工作者未进行过详细研究,笼统地将其归入中生代上白垩统。本文作者在该地野外考察时,首次发现丰富的叶肢介、介形类和哺乳动物等化石并详细测制了地层剖面,作了分层工作。根据化石特征,为本区早第三纪动物群性质和地层对比提供了依据。经研究共发现2属11种(7个新种)叶肢介化石,并对新种进行了描述和对比。

The red terrestrial facies of fragmental rock bed, which was roughly classified into the upper Cretaceous series of Mesozoic by former geologists without detailed study, is hosted in the Meigeng area, Guichi, Anhui, of the western section of the Tongling Basin on the south bank of the Yangtze River. The author, when conducting the field work, first found plenty of Fossil Conchostraca, Ostraco- daical, Mammal, etc., and made a thorough stratigraphical section and division. Fossil Conchostraca fall into two genera of eleven species, of which seven new ones are described and correlated. It provides a basis for the correlation of stratigraphy with the nature of Eogene fauna mass.
