In the present study, the taxonomical and palaeoecological interpretations of non-marine ostracod assemblages from the Gračanica opencast coal mine are summarised. The results revealed three different ostracod assemblages within a 40-m succession. The oldest ostracod assemblage from the lower part of the section consisted primarily of pioneer species Fabaeformiscandona cf. pokornyi, Vestalenula cylindrica, Paralimnocythere rostrata, Cyclocypris ovum and Mediocypris cf. candonaeformis. Determined ostracods indicated a very shallow environment, with a low water energy. The second ostracod assemblage with the dominant species Cypridopsis cf. biplanata in the middle part of the succession corresponded to a shallow littoral environment, rich in vegetation with gradual water deepening. The third ostracod assemblage occurred in the upper part of the Gračanica section. Generally, marly sediments of the upper part of the succession contained abundant, thin, transparent and very poorly preserved ostracod valves that belonged to Candonidae gen. et sp. indet. taxon typical for a lake environment.

在本研究中，归纳了Gračanica露天煤矿的非海洋类兽类组合的分类学和古生态学解释。结果揭示了在40米连续范围内的三种不同的成龙类组合。该部分下部最古老的兽脚类动物组合主要由先锋物种Fabaeformiscandona cf组成。pokornyi，Vestalenula白茅，Paralimnocythere喙，Cyclocypris卵子和Mediocypris比照 弓形虫 确定的兽脚类动物表明环境很浅，水能很低。与优势种Cypridopsis的第二种成龙纲cf. 演替区中部的双平面对应于浅海沿岸环境，植被丰富，水逐渐深化。第三次耳足类动物组合发生在Gračanica部分的上部。通常，该序列上部的马里沉积物含有丰富的，稀薄的，透明的且保存得非常差的属于犬齿科的成虫瓣。等。indet。湖泊环境中典型的分类单元。
