Warm water benthic foraminifera document the Pennsylvanian–Permian warming and cooling events — The record from the Western Pangea tropical shelves

Middle Permian U–Pb zircon ages of the “glacial” deposits of the Atkan Formation, Ayan-Yuryakh anticlinorium, Magadan province, NE Russia: Their significance for global climatic interpretations

“…The P3 or P4 cold climatic episodes in southern Gondwana are well correlated with global warming and cooling episodes documented in the record of benthic warmwater foraminifera along the North American continental shelves (Davydov, 2014). The global climatic warming events are associated with diversity peaks and with migration events of warm-water fusulinids into temperate North American shelves.…”

“…The lack of analyses on the dynamics of fusulinid evolution within the Capitanian, as mentioned in the studies described above (Isozaki et al, 2007 etc. ), conceal the fact that the highest diversity among Capitanian fusulinids occurs at the end of the stage (Chedia, 1987;Davydov, 2014;Leven, 2003;Ozawa, 1987), where, following the logic of the progressive cooling development (Isozaki et al, 2007), the diversity should be the lowest. Another feature that is contradictory to the proposed extinction/cooling during the entire Capitanian is the existence of a diverse assemblage of fusulinids, including advanced neoschwagerinids such as Lepidolina, in southern China in the type section of the Capitanian-Wuchiapingian boundary (Penglangton section), up to the top of the Capitanian J. granti/Clarkina postbittery hongshuensis conodont zones (Shen et al, 2007;V.I.…”

Biotic paleothermometry constrains on Arctic plates reconstructions: Carboniferous and Permian (Zhokhov Island, De-Longa Group Islands, New Siberian Archipelago)

“…This age is consistent with the previously published coral data [ Makeev et al ., ]. The presence of diverse algae, fusulinids, and rugose corals suggests the occurrence of this location within the warm‐water tropics‐subtropics of the early Moscovian global interglacial warming episode [ Davydov , ].…”

“…Therefore, the records of paleoclimate dynamics must be a part of the paleotectonic/paleogeographic reconstructions. Taking into account that early Moscovian perhaps was the time of global warm climate [ Davydov , ], we can suppose the paleoposition of Zhokhov Island at this time around 35°N. Also, in order to correctly understand the biogeography of the regions, only assemblages proved to be isochronous must be analyzed.…”

Evolution and Geological Significance of Larger Benthic Foraminifera

“…2.31). This analysis has recently been greatly expanded by Davydov (2014), who points out that the first occurrences of Tethyan fusulinides in North America are associated with paleoclimatic warming events, and that the time of the delay of the first occurrences (see Fig. 2.25) depended on the scale and intensity of the warming episodes during those periods.…”
