“…Marine Lopingian deposits are also widely distributed in the Russian Far East, the Verkhoyansk Folded Belt, the Kolyma-Omolon Block (see review of Shi, 2006). In the Russian Far East, the Lopingian Series is represented by the foraminifer Colaniella parva Zone and the Wuchiapingian Clarkina orientalis Zone and the overlying Clarkina cf.…”

The Lopingian represents the last epoch of the Palaeozoic Era and is bracketed by two severe biotic mass extinctions associated with dramatic environmental changes. The Lopingian Epoch lasted about 7 millions years and was also bracketed by large volcanic eruptions with the Emeishan volcanics at the base and the Siberian traps at the top. Considerable data have accumulated recently and in this paper we attempt to summarize these findings in a high-resolution Lopingian (Late Permian) timescale that integrates currently available multiple biostratigraphic, isotope chemostratigraphic, geochronologic and magnetostratigraphic data. In South China at least 13 conodont zones, multiple polarity zones and large carbon isotope fluctuations in the Lopingian are recognized and provide the high-resolution calibration that is essential to study this Late Permian interval characterized by Earth's largest biotic extinction. We also present a global correlation chart for the marine Lopingian Series.

“…If one extends the warm/hot, tropical-subtropical climatic zones established on the stable platforms, following the Boucot et al (2013) compilation across the oceans, Panthalassa in particular, one can then conclude that the platform marginal Tethyan faunas of the Permian and Jurassic were derived from the Permian and Mesozoic tropical-subtropical belt and then transported northeasterly to collide and become part of western North America, or were transported northwesterly to become part of eastern Asia, or were transported southwesterly to become part of North Island, New Zealand. Shi (2006) Mizutani & Kojima (1992) summarized the relation of Japanese units to those as far North as the Khabarovsk area, with radiolarian descriptive material which implies that both areas include Tethyan radiolaria. Tilman et al (1982) provided an overview of the tectonic complexities of the Kamchatkan Koryak area.…”
Tropical-subtropical fossils (certain fusuline foraminifera, certain radiolaria, certain bivalves, certain corals) of Permian and Jurassic age now occur in Northern Pacific Asian and North American marginal areas. Their presence indicates original locations in tropical-subtropical, warm water "central" Panthalassa from which they were transported and accreted to cooler water areas. This information, palaeontological and lithological is the basis for the conclusions made here.• Key words: Permian oceanic palaeogeography, post-Permian movements from mid-Panthalassa sources, bedded oceanic chert records.BOUCOT, A.J. 2015.
