| Summary: | S4. Palaeogeographic sketch for Early Campanian. Distribution of the foraminifera and radiolaria in the EEP and in the Crimea–Caucasus area. White colour—land, area of denudation or erosian; blue colour—marine sediments. 1— Oxytoma teniucostata (Roemer), boreal bivalve migrant from Western Siberia; 2— Marsupites testudinarius Schlotheim, crinoids from Tethys area. Calcareous benthic foraminifera of the Pseudogavelinella clementiana Zone: 3— P. clementiana (d'Orbigny); 4— Bolivinoides decoratus Jones. Planktonic foraminifera of Globotruncana arca beds on Mangyshlak MTS: 5— Globotruncana arca (Cushman); planktonic foraminifera of Globotruncanita elevata Zone in Crimea–Caucasus area: 6— Globotruncanita elevata (Brotzen). Radiolaria: 7—boreal radiolaria Prunobrachidae . |
