Fig. 3 in Extremely Rare Turonian Belemnites from the Bohemian Cretaceous Basin and Their Palaeogeographical Importance

Fig. 3. Palaeogeographic map of the Northern hemisphere (North pole projection). 1, Cenomanian belemnitellid radiation centre (Russian Platform); 2, Lower Turonian records (Agapa river, northwest Siberia); 3, North American Middle Turonian records; 4, Upper Turonian record from Greenland; 5, Upper Turonian records from the Bohemian Cretaceous Basin, Germany and south Sweden. Dashed line indicates palaeobiogeographic barrier during the latest Cenomanian through early Coniacian. Dots indicate the possible migration pathway; grey are land areas during the Late Cretaceous, white are seas and oceans. Modified after Košťák and Wiese (2006, 2008).
