Abstract
A late Changhsingian bivalve complex including species from the genera Palaeonucula, Dacryomya, Malletia ?, Sarepta ?, Myalina, Pteria, Maitaia, and Unionites is discovered in northeastern Asia for the first time. The transition from the Permian to the Triassic in high-boreal basins has been shown to include two extinction episodes similar to those observed in the low-boreal basins and apparently evoked by trap volcanism activation in Siberia. Changes in benthic foraminifera diversity and vertical distribution of ammonoidea of the genus Otoceras in transitional Permian–Triassic deposits also are considered. Images of bivalves from the most typical taxa are presented.

We have obtained the first detailed δ13Сorg record in Permian-Triassic boundary sediments in deepwater facies in Northeast Asia (Kolyma–Omolon region, Balygychan Basin). Our data show good convergence both with the Setorym River section (South Verkoyansk region), where the Permian-Triassic boundary has been determined approximately, and with a number of other sections of Permian-Triassic boundary sediments in the Boreal and Tethyan Superrealms, in particular, in the Buchanan Lake section in Arct...

Abstract We present new data on the structure and age of the upper Permian strata in the basin of the Setorym River (tributary of the Vostochnaya Khandyga River) in the South Verkhoyansk region, represented by the Imtachan Formation and the lower part of the Nekuchan Formation. Based on the new findings of bivalve fossils from the Intomodesma costatum Zone, as well as on the study of carbon isotopes in the shells and carbon isotopes of the organic matter of the host mudstones, we have for the fi...

This paper is dedicated to the global correlation of the marine Permian-Triassic boundary layers based on some published and original data on the δ13Corg and δ13Ccarb values obtained for the section along the Suol Creek (Setorym River, southern Verkhoyansk region). The section includes six carbon-isotope intervals readily distinguished in the corresponding curves obtained for several Permian and Triassic reference sections in Eurasia and North America including palleontologically well substantia...

A high-resolution chemostratigraphic study of a 24-m-thick section at West Blind Fiord on Ellesmere Island (Canadian Arctic) documents stepwise environmental deterioration in the marine Sverdrup Basin during the late Changhsingian (late Late Permian) as a result of volcanic disturbances to surrounding landmasses. A horizon within the upper Lindstrom Formation (datum A) is characterized by increased Fe-oxyhydroxide fl uxes and weathering intensity as well as modest shifts toward more reducing wat...

It is well known that the Permian‐Triassic transition was marked by significant changes in the biota and sedimentation settings. Evidence for the development of anoxic environments in various world areas during events at the Permian‐Triassic transition in both shallow- and deep-water settings are reported in [1‐8 and others]. Such data have been unavailable thus far for the Russian territory. The study of Permian‐Triassic boundary deepwater sediments in Northeast Asia provided the first evidence...

The Permian-Triassic extinction pattern in the peri-Gondwanan region is documented biostratigraphically, geochemically and sedimentologically based on three marine sequences deposited in southern Tibet and comparisons with the sections in the Salt Range, Pakistan and Kashmir. Results of biostratigraphical ranges for the marine faunas reveal an end-Permian event comparable in timing with that known at the Meishan section in low palaeolatitude as well as Spitsbergen and East Greenland in northern ...

A newly studied Permian-Triassic (P-Tr) boundary section in Jameson Land, East Greenland, contains an abundant and well-preserved marine fauna as well as terrestrial palynomorphs. For the first time it is possible to compare the biotic crises of the marine and terrestrial realms using the same samples from the same section. The sediments record a negative excursion in δ 13 C carb values of 8‰–9‰, and in δ 13 C org values of 10‰–11‰. The presence of the conodont Hindeodus parvus, combined with th...

Abstract The duration of early Triassic anoxia in the carbonate ramp settings of the Werfen Formation (Dolomites, northern Italy) has been constrained using ichnofabric and sedimentological data. This includes fine lamination and abundant pyrite framboids commonly reworked into lags by storm events. The “anoxic” event spanned the entire Griesbachian Stage and extended from deep waters into extraordinarily shallow water settings; evidence for oxygen deficiency can be found in mid and inner ramp f...

Facies, faunal and geochemical evidence from the Permian/Triassic boundary sediments of the Dolomites and Idaho indicates a major anoxic event in the earliest Triassic. In both regions, the basal beds consist of finely laminated micrites with common syngenetic pyrite. The only fauna consists of occasional bedding plane assemblages of Lingula or Clacaria, a typical lower dysaerobic assemblage. This is a level where previous studies have shown a major negative carbon isotope excursion and a cerium...

Abstract This contribution considers the fossil content of the three Eastern Province ‘central’ terranes discussed within this Memoir, namely the Brook Street Terrane, the Dun Mountain–Maitai Terrane and the Murihiku Terrane, and reviews the evidence and/or arguments for the current interpretation of their age ranges as determined from fossils. It also briefly considers the Permian–Triassic record of the Western Province. There has been limited new palaeontological discovery in the past few deca...
