This is an account of finds of stratigraphically useful calcareous nannofossils and the magnetostratigraphy of the Jurassic-Cretaceous boundary interval of the eastern Crimean peninsula (southern Ukraine). We compare these new complementary results with those presented by our team in earlier publications. A missing interval in the Crimean sequence is filled, and the position of the Tithonian-Berriasian (J/K) boundary is confirmed

乌克兰南部 J/K 边界层段生物和磁地层学的进一步观察

这是对地层有用的钙质超微化石的发现以及克里米亚半岛东部（乌克兰南部）侏罗纪-白垩纪边界区间的磁地层学的描述。我们将这些新的互补结果与我们团队在早期出版物中提出的结果进行比较。克里米亚序列中缺失的区间被填补，Tithonian-Berriasian (J/K) 边界的位置得到确认
