Resumen:
Thisarticle is concerned with nannofossil study of Tithonian?Berriasian sedimentsof Eastern Crimea. The NJT 16, NJT 17a, NJT 17b, NKT, and NK 1 nannofossilzones were determined. The occurrence of Nannoconus kamptneri minor, one of thepotential marker-types of the Tithonian?Berriasian boundary (the base of theNKT Zone) of the Tethyan sequence in the Feodosiyan section is assigned here tothe Pseudosubplanites grandis ammonite Subzone and the magnetic Chron M18n. Thebase of the NKT Zone is closer to the Grandis Subzone base than to the base ofthe Jacobi Subzone. Contradictions in the interpretation of magnetic chronsobtained by the present authors (Arkadiev et al. 2018) and by Bakhmutov et al.(2018) might be caused by mistakes admitted in the latter work on the compiledsection.
