Abstract
In this article there are the results of sedimentological, palynological and paleomagnetic studies of upper Cretaceous in Alan-Kyr section (Central Crimea). The nomenclature of rocks was specified, and their deep-water genesis was justified. According to palynologic data, the age of sediments is estimated as late Campanian, in the lower part of the section palynomorphs were not found. In the lower part of the section there was established a reverse polarity magnetozone — probable analogue of C33r magnetic chron, which base should be desirable to use as a primary attribute to determine the lower border of Campanian stage in the section according to Wolfring’s recommendation [Wolfgring et al., 2018]. The received data found a significant divergence microfaunistic dating of the section, conducted before [Bragina et al., 2016].
