Abstract:

Carboniferous and Permian carbonate sequences in Japan are most completely preserved in the Akiyoshi Limestone in the Akiyoshi Terrane (Permian accretionary complex), Southwest Japan. The studied Sakmarian to lower Kungurian sequence is biostratigraphically divided into six zones: Globifusulina nux Zone and Globifusulina krotowi Zone (Sakmarian), Chalaroschwagerina vulgaris Zone (lower to middle Artinskian), Paraleeina magna Zone (upper Artinskian), Pamirina leveni Zone (uppermost Artinskian), and Miselllina dyhrenfurthi Zone (lower Kungurian) based on stratigraphic distribution and species co

Abstract:

aximum-marine flooding levels and marine-condensed sections from uppermost Carboniferous and Lower Permian fourth-order (0.1-1 m.y.) depositional sequences of the North American midcontinent reveal a rich stratigraphic succession of species of Streptognathodus and Sweetognathus conodonts that permits high-precision correlation of the Carboniferous-Permian boundary as well as the Asselian-Sakmarian and Sakmarian-Artinskian boundaries. Eleven new species of Streptognathodus are described: Streptognathodus binodosus, S. denticulatus, S. elongianus, S. florensis, S. lineatus, S. nevaensis, S. post

A biostratigraphic division of the Lower Permian into brachiopod zones of Jakutoproductus verkhoyanicus, Jakutoproductus insignis, Jakutoproductus terechovi, and Jakutoproductus rugosus is observed within the Northern and Western Verkhoyanie. According to the literature, only the complex of the lower biostratigraphic unit (Verkhoyanicus Zone) was previously confidently established in the Southern Verkhoyanie. Meanwhile, representatives of the two middle zones were not observed, and the presence of the index species of the Rugosus zone was only indicated in the southern part of the region (Yudo

AbstractThe Anatolian Platform, which was a part of the Gondwanan Platform, is mainly characterized by carbonate-dominated deposits ranging in age from Devonian to Permian. The biostratigraphy and systematics of a late Asselian–early Sakmarian fusulinid fauna from the Anatolian Platform including Eastern and Central Taurides have been investigated in three sections: Özbek Hill, Eskibey and Bademli. Twenty-four fusulinid taxa, belonging to twelve genera, were determined in a single fusulinid zone dated as late Asselian–early Sakmarian. Early–middle Asselian fusulinid faunas have not been observ

Abstract:

Sclerochronology was conducted on the pedicle valves of four Sakmarian-age brachiopods (Squamaria moorei) to constrain climate model predictions of temperature seasonality along western equatorial Pangaea (WEP). The brachiopods are from a Lower Permian section within the Robledo Mountains, NM, and they reveal seasonal trends of δ18O and temperature for that interval that suggest global warming and moderation of seasonality. Elemental and SEM analyses verified the specimens were well preserved. δ18O profiles show a relatively rapid and consistent two-year growth rate corresponding to the organi

Abstract:

A thick succession of upper Paleozoic carbonate rocks and minor chert crops out north of the head of Otto Fiord (northwest [NW] Ellesmere Island, Nunavut) in the Canadian Arctic Archipelago. These rocks accumulated in a tectonic subbasin—the Otto Fiord Depression (OFD)—of the Sverdrup Basin that likely originated through rifting during late Early Carboniferous (Serpukhovian). Following a long interval of passive subsidence that allowed a thick succession of Moscovian–Kasimovian carbonate rocks to fill the OFD, tectonic activity resumed during the Gzhelian (Late Pennsylvanian). This resulted in

This wedge of sediments, which tapers over less than 2 km from 1341 m in the west to 588 m in the east, comprises

The stratal architecture of the upper Ely Limestone and Mormon Gap Formation (Pennsylvanian–Lower Permian) in west-central Utah reflects the interaction of icehouse sea-level change and tectonic activity in the distal Antler–Sonoma foreland basin. Nineteen stratigraphic sections correlated by physical and biostratigraphic means provide a basis for tracing Carboniferous–Permian boundary strata over a north–south distance of 60 km. These formations can be subdivided into 14 unconformity-bounded, third-order depositional sequences of differing internal architecture and regional extent. Conodonts
