Fig. 11From: Berriasian planktonic foraminifera and calcareous nannofossils from Crimea Mountains, with reference to microfossil evolutionTaxonomic diversity (species richness) of nannofossils and dinoflagellates in Jurassic through Early Cretaceous time (after Olde et al. 2015 and Bown et al. 2004). To the right, the (meagre) taxonomic diversity of Jurassic planktonic foraminifera from Jurassic into Berriasian is plotted as number of taxa identified. For details, see textBack to article page
