Global Conodont Paleobiogeography of the Tournaisian Stage (Early Carboniferous)

For the first time a scheme for the paleobiogeographical zoning of Tournaisian conodonts is proposed on a global scale, based on the analysis of their spatio-temporal distribution. The Boreal, Equatorial and Notal superrealms are established. The Boreal Superrealm includes the Arctic and Siberian-Alaskan realms, the first is represented by the Kharaulakh-Novosibirsk and North-Uralian provinces, and the second is represented by the Omolon, South Siberian and Alaskan provinces. In the Equatorial Superrealm, the Volga-Ural-Tien Shan, European-Iranian, Hindustan-Chinese, Australian and Western North American realms are distinguished. The Volga-Ural-Tien Shan Realm is represented by the Ural-Tien Shan and East European provinces. In the Ural-Tien Shan Province are the Uralian, Priuralsk, Mugodzhar and Tien Shan subprovinces, in the East European Province are the Pechora, Moscow, Donbass and Transcaucasia subprovinces. The European-Arabian Realm is divided into the English-Spanish, Pomeranian, Dzikowiec-Kovalai and Caucasian-Arabian provinces, the first is divided into by the English-Spanish, Italian, Pomeranian, Dzikowiec-Kovalai and Caucasian-Arabian provinces. The Hindustan-Chinese Realm is represented by the Tarim and South Chinese provinces. In the Australian and Western North American realms, provinces are not distinguished.
