The paper presents the results of U–Pb isotope dating (LA-ICP-MS, Collective Use Center of the Geological Institute of the Russian Academy of Sciences) of detrital zircons from sandstones of the Upper Cretaceous (Maastrichtian) – Lower Paleogene (Danian) boundary level sections of the Klementyev Mountain section of the Uzyn-Syrt Upland (eastern Crimean Mountains). The obtained data set from the Upper Maastrichtian Klementyev Fm. (sample K22-001) contains 5 Jurassic dates, 22 Triassic dates, 55 P
