Carbon cycle perturbations and environmental change of the middle permian and Late Triassic Paleo-Antarctic circle [PDF]
Scientific ReportsDuring the middle Permian through the Triassic, Tasmania moved from paleo-latitudes of 78° to 69°S, wedged between Antarctica and Australia, within the paleo-South polar circle.

Early-middle Permian Mediterranean gorgonopsian suggests an equatorial origin of therapsids. [PDF]
Nat CommunAbstractTherapsids were a dominant component of middle–late Permian terrestrial ecosystems worldwide, eventually giving rise to mammals during the early Mesozoic. However, little is currently known about the time and place of origin of Therapsida. Here we describe a definitive therapsid from the lower–?middle Permian palaeotropics, a partial skeleton ...

Size-frequency distributions along a latitudinal gradient in Middle Permian fusulinoideans. [PDF]
PLoS One, 2012 Geographic gradients in body size within and among living species are commonly used to identify controls on the long-term evolution of organism size. However, the persistence of these gradients over evolutionary time remains largely unknown because ancient biogeographic variation in organism size is poorly documented.

Evolution of prototype basin and change of tectonic-sedimentary pattern in Paleozoic, Ordos Basin
Shiyou shiyan dizhi, 2022 The Ordos Basin is a craton basin developed based on the Precambrian rift system during Permian. It has experienced two stages of evolution including the Early Paleozoic craton marginal depression and Late Paleozoic intra-craton depression.

Early evolution of beetles regulated by the end-Permian deforestation
eLife, 2021 The end-Permian mass extinction (EPME) led to a severe terrestrial ecosystem collapse. However, the ecological response of insects—the most diverse group of organisms on Earth—to the EPME remains poorly understood.

Early-Middle Permian palynoflora of Shandong Province, eastern North China
Journal of Palaeogeography, 2020 The Permian Taiyuan and Shanxi formations exposed in Shandong Province, eastern North China, contain abundant spores and pollen. In this study, a total of 42 genera and 146 species of spores and pollen from these Permian formations, native to northern ...

Simulated warm polar currents during the middle Permian [PDF]
Paleoceanography, 2002 During Permian stage 6 (Wordian, Kazanian) the Pangaean supercontinent was surrounded by a superocean: Panthalassa. An ocean general circulation model has been coupled to an atmospheric energy balance model to simulate the sensitivity of the Wordian climate (∼265 million years ago) to changes in greenhouse gas concentrations, high‐latitude geography ...
