文摘
- •
Foraminifera and radiolarians have been investigated from the same Cenomanian–Campanian samples of the Crimea–Caucasus region.
- •
The first crisis coincides with the Cenomanian–Turonian boundary event, connected to the sea level rise, warm greenhouse and OAE 2.
- •
The diversification is related to a sea-level highstand and hot greenhouse climatic environment.
- •
The wider distribution of the family Prunobrachidae reflects the beginning of cooling greenhouse episode.
