Abstract Seven species of atelostomate (irregular) echinoids are described from Upper Cretaceous marl-limestone alternations in the vicinity of the village of Kalafatli (province of Zonguldak, Black Sea region, northern Turkey), namely Stenonaster tuberculatus, Echinocorys scutata forma pyramidata, Rispolia sp., Seunaster lamberti, Micraster (M.) coravium, Micraster (Gibbaster) stolleyi and Coraster aff. alapliensis. An integrated biostratigraphical approach using calcareous nannofossils, inoceramid bivalves and these echinoids has revealed a possibly late early Campanian to early late Campanian age for this succession. Although the palaeogeographical position of the study area is along the northern margin of the Tethyan Ocean, the echinoid species recorded indicate a palaeobiogeographical link to the Boreal Realm of northern Europe. In view of the fact that the echinoid record in this area of the Tethyan Province is generally sparse, the new finds allow a reconstruction of possible echinoid migration patterns during the Late Cretaceous and improve the regional stratigraphy.

来自北特提斯省（Zonguldak，土耳其北部）的晚白垩世（Campanian）海胆类及其古生物地理意义

摘要 在 Kalafatli 村（土耳其北部黑海地区宗古尔达克省）附近的上白垩统泥灰岩-石灰岩交替中描述了七种无端口（不规则）海胆，即 Stenonaster tuberculatus、Echinocorys scutata forma pyramidata、Rispolia sp .、Seunasterlamberti、Micraster (M.) coravium、Micraster (Gibbaster) stolleyi 和 Coraster aff。阿拉普里 使用钙质纳米化石、inoceramid 双壳类动物和这些海胆类的综合生物地层学方法揭示了这种演替可能是早坎帕阶晚期至晚坎帕阶早期。尽管研究区的古地理位置位于特提斯洋的北缘，但记录的海胆类物种表明与北欧北方地区存在古生物地理联系。
