Twenty-one outcrop samples collected from a 28-m-thick section from the Safranbolu Formation of the southwestern part of the Safranbolu Basin, Anatolia, Turkey yielded well-preserved benthic foraminifera belonging mainly to the genera Alveolina , Nummulites , Assilina , Rotalia , Disclocyclina and Orbitolites. Alveolina is the most diversified genus that is represented by sixteen species: Alveolina archiaci , A. axiampla , A. barattoloi , A. carantana , A. colatiensis , A. cuspidata , A. distefanoi , A. histrica , A. lehneri , A. oblonga , A. polatliensis , A. rakoveci gueroli , A. ruetimeyeri , A. rugosa , A. safranboluensis and A. sirelii . Alveolina safranboluensis and A. sirelii are described new. Comparison of the fossil assemblage with those assemblages previously reported from both Turkey and other Tethyan sub-basins revealed that the deposition occurred during the Cuisian (Eocene) and corresponded to Shallow Benthic Foraminiferal Zones (SBFZ) 10–12. The abundance and diversity of the larger benthic foraminifera indicated that the Safranbolu Formation was deposited under transgressive conditions.

来自土耳其安纳托利亚西北部 Safranbolu 组（Cuisian，始新世）的底栖有孔虫组合

从土耳其安纳托利亚 Safranbolu 盆地西南部 Safranbolu 组 28 米厚剖面采集的 21 个露头样品产生了保存完好的底栖有孔虫，主要属于 Alveolina 属、Nummulites 属、Assilina 属、Rotalia 属、Disclocyclina 属和轨道石。Alveolina 是最多样化的属，由 16 个物种代表：Alveolina archiaci、A. axiampla、A. barattoloi、A. carantana、A. colatiensis、A. cuspidata、A. distefanoi、A. histrica、A. lehneri、A. oblonga、A. polatliensis、A. rakoveci gueroli、A. ruetimeyeri、A. rugosa、A. safranboluensis 和 A. sirelii。Alveolina safranboluensis 和 A. sirelii 被描述为新的。将化石组合与先前从土耳其和其他特提斯亚盆地报告的组合进行比较，发现沉积发生在崔西亚（始新世）期间，对应于浅底有孔虫区（SBFZ）10-12。较大底栖有孔虫的丰度和多样性表明番红花组是在海侵条件下沉积的。
