Abstract

The Campanian and Maastrichtian radiolarian assemblages are known from many regions of the Tethyan Superrealm. Unfortunately, only some of them are reliably dated and completely studied as paleontological assemblages. The analysis of evolution of radiolarians is based on Campanian to Maastrichtian assemblages from Crimea, Cyprus, and Serbia properly dated and studied in detail with addition of data from California, Turkey, the World Ocean, and other regions. It is concluded that renewal of assemblages took place in the Campanian and Maastrichtian relatively slowly. The biodiversity was slowly reduced at the generic level. The history of radiolarian evolution in the end of the Late Cretaceous can be subdivided to several stages: late Santonian–early Campanian, early Campanian–late Campanian, late Campanian–early Maastrichtian, and late Maastrichtian.

坎潘期和马斯特里赫期的放射虫演化特征及详细地层学的前景

摘要

在特提斯超界的许多地区都知道坎帕尼亚人和马斯特里赫特人的放射虫组合。不幸的是，只有其中一些可靠地注明了日期，并且作为古生物学组合进行了完整的研究。放射虫进化的分析是基于来自克里米亚，塞浦路斯和塞尔维亚的Campanian到Maastrichtian的组合，并进行了适当的日期和详细研究，并添加了来自加利福尼亚，土耳其，世界海洋和其他地区的数据。可以得出结论，Campanian和Maastrichtian的聚会更新相对较慢。生物多样性在一般一级缓慢减少。白垩纪末期放射虫演化的历史可分为以下几个阶段：桑托尼晚期-坎帕尼早期，坎帕尼早期-坎帕尼晚期，坎帕尼晚期-马斯特里赫特早期，
