title: Coniacian-Campanian Alan-Kyr section of the Mountainous Crimea: biostratigraphy and palaebiogeography
abstract: This article is a continuation of study of the reference section Alan Kyr (Central Crimea, Belogorsk region). Recorded the difference in age between complexes dating of radiolarians and planktonic foraminifera and benthic foraminifera. A likely explanation for this can be assumed that in the Crimea stratigraphically important taxa could appear before f few million years. Than on the platform where they could migrate during major global eustatic transgression in the early Campanian age. The artic
