The dataset presents quantitative information on the taxa distribution of calcareous nannoplankton and smaller benthic foraminifera retrieved from the nummulitic accumulation in the Transylvanian Basin (Romania). Until now, only the larger benthic foraminifera and bryozoans were systematically studied, data on calcareous nannoplankton and smaller benthic foraminifera are scares. Our data comprise of quantitative information on the calcareous nannoplankton and smaller benthic foraminifera (raw individuals counts, relative abundance), diversity indices, benthic foraminifera dissolved oxygen index - BFOI and normalised data (ARCSIN values) used for clustering and principal component analysis. These data provide information on paleoenvironmental changes in the north-western part of the Transylvanian Basin during the middle Eocene (Bartonian) and can be used in any comparative study on the reconstruction and paleoenvironmental interpretation of the nummulitic carbonate reservoirs from Tethyan regions. The present data article is associated with the research paper "In the shadow of giants: Calcareous nannoplankton and smaller benthic foraminifera from an Eocene nummulitic accumulation (Transylvanian Basin, Romania)" by Bindiu-Haitonic et al. 2021 [1].
该数据集提供了从特兰西瓦尼亚盆地（罗马尼亚）的钱币状堆积物中获取的钙质超微浮游生物和小型底栖有孔虫类群分布的定量信息。到目前为止，仅对大型底栖有孔虫类和苔藓虫进行了系统研究，关于钙质超微浮游生物和小型底栖有孔虫的数据很少。我们的数据包括钙质超微浮游生物和小型底栖有孔虫的定量信息（原始个体计数、相对丰度）、多样性指数、底栖有孔虫溶解氧指数 - BFOI以及用于聚类和主成分分析的标准化数据（反正弦值）。这些数据提供了始新世中期（巴通阶）特兰西瓦尼亚盆地西北部古环境变化的信息，可用于任何关于特提斯地区钱币状碳酸盐储层重建和古环境解释的比较研究。本数据文章与Bindiu - Haitonic等人于2021年发表的研究论文《在巨头的阴影下：来自始新世钱币状堆积物（罗马尼亚特兰西瓦尼亚盆地）的钙质超微浮游生物和小型底栖有孔虫》[1]相关。
