Middle-Late Permian mass extinction on land
Geological Society of America Bulletin, 2006The end-Permian mass extinction has been envisaged as the nadir of biodiversity decline due to increasing volcanic gas emissions over some 9 million years. We propose a different tempo and mechanism of extinction because we recognize two separate but geologically abrupt mass extinctions on land, one terminating the Middle Permian (Guadalupian) at 260.4

Middle Permian cephalopods of the Volga-Ural Region
Paleontological Journal, 2014A diverse assemblage of Kazanian nautiloids and ammonoids from two localities in the Kirov Region and the Mari El Republic is studied and described for the first time. The biostratigraphic potential of the cephalopod assemblage, and its ecological and taphonomic affinities, are analyzed. Twenty nautiloid species (of which 18 are new) and eight ammonoid

Guadalupian (Middle Permian) paleobiogeography of the Neotethys Ocean
Gondwana Research, 2013Abstract A matrix of presence/absence data of Guadalupian (Middle Permian) brachiopod genera from Sicily, Tunisia, Oman, Turkey, north Iran, central Afghanistan, Karakoram, Salt Range, and south Thailand has been analyzed by multivariate methods (cluster analysis, principal coordinate analysis, minimum spanning trees) and Parsimony Analysis of ...

Early Kazanian (Middle Permian) Gastropods
Paleontological Journal, 2018Taxonomy and stratigraphic distribution of the Early Kazanian gastropods of the Volga–Ural Region are studied. The material previously studied by Netchaev and collections from the northern areas of the paleobasin previously described by Licharew are reexamined.

Updated digital paleogeography for East Tethys from Middle Permian to Middle Triassic
2023Deep-time geographic maps are the setting base of geological research and integrated windows for looking the past earth. Reconstructing paleogeography involves the evolution of the earth’s surface tectonic process, the pattern of land and sea, climate, and biology in geological history.

Calculating eustatic amplitude of middle Permian from reefs
Science in China Series D: Earth Sciences, 2002Methods for calculating ancient eustatic change amplitudes according to reef fabric- facies are proposed, with a new method for determining sediment-loading subsidence. Compared with methods based on non-reefal deposits, these methods are more accurate in restoration of original sediment thickness, determination of sediment-loading subsidence, as well ...

THE MIDDLE PERMIAN ROCKS OF YORKSHIRE.
Proceedings of the Yorkshire Geological Society, 1925From Knaresborough southwards to the line at which the Upper Magnesian Limestone dies out, the two beds of limestone are separated by a series of clastic deposits. These consist of marls, sandstones, and, locally, of breccias, with chemical deposits of gypsum, salt and dolomite.

Continental arc volcanism fueled Middle Permian warming
GeologyThe Middle Permian was characterized by a major climatic warming trend that heralded the end of the late Paleozoic Ice Age, as well as by widespread marine anoxia during the Capitanian biotic crisis. Although the Emeishan large igneous province (ELIP) has been implicated as a potential driver of this warming, its role remains contentious.
