【摘要】 <正> 南宁盆地脊椎动物化石地点目前所知不下七处。本文着重记述了1974和1979年笔者采自邕宁县五塘公社莲塘村的石炭兽化石,并对盆地东部下第三系作一初步划分。本文首次报道南宁盆地发现脊椎动物化石,对研究石炭兽的演化、发展和分布,对盆地第三系地层的划分和对比,提供了新的依据。一、化石地点及地层概况莲塘村位于南宁市东北约32公里、五塘圩东5公里、邕宾(南宁—宾阳)公路南侧。石炭兽化石产于莲塘村东约300米远的小煤窑、距地表8.3米深的褐煤层顶板(灰色泥质粉砂岩)中。更多还原

【Abstract】 The described Oligocene vertebrate fossils were collected in lake and swamp deposits of the Nanning Basin.The Lower Tertiary is subdivided into three formations.1. The Red Stone Formation: This Formation is 100-220 meters in thickness. It is considered early to middle Eocene in age.2. The Naduo Formation: That the lake and swamp deposits contain lignite. This Formation is 143-228 meters in thickness. It is considered late Eocene in age.3. The Yongning Formation: This Formation consists of three members.The lower member: That the swamp deposits contain lignite. This member is 191 meters in thickness. It is considered early Oligocene in age. The species of fossils includes: Heothema nanningensis sp. nov. Crocodilus sp.The middle member: That the lake deposits. This member is 188 meters in thickness. It is considered Oligocene in age.The upper member: That the swamp deposits contain lignite. This member is >264 meters in thickness. It is considered Oligocene in age. The species of fossils includes: Crocodilus sp. Pseudobagrus sp. Emydidae gen. et sp. indet.更多还原
