The fossil record of Peronosporomycetes (water moulds) is rather sparse, though their distinctive ornamentation means they are probably better reported than some true fungal groups. Here we describe a rare Palaeozoic occurrence of this group from a Guadalupian (Middle Permian) silicified peat deposit in the Bainmedart Coal Measures, Prince Charles Mountains, Antarctica. Specimens are numerous a...

Globally, Late Permian to Early Triassic carbonate rocks record several pronounced positive and negative C-isotope excursions, indicating a dramatic reorganization of the global carbon cycle. These C-isotopic anomalies provide important constraints on environmental changes that occurred during end-Permian extinction subsequent delayed biotic recovery. In this study, we present high-resolution d...

The late Paleozoic ice age (LPIA) during the Carboniferous and Permian (ca. 360–260 Ma) was vegetated Earth's only recorded icehouse-to-greenhouse transition provides a deep-time perspective for climate-glaciation-environment coevolution future climate change. During LPIA, changes in glacial-interglacial cycles have been closely linked to atmospheric pCO2. In this paper, we investigate relation...

Recent evidence quite convincingly indicates that the Late Permian biotic crisis was in fact a binary extinction with a distinct end-Guadalupian extinction pulse preceding the major terminal end-Permian Tartarian event by 5 million years. In addition anoxia appears to be closely associated with each of these end-Paleozoic binary extinctions. Most leading models cannot explain both anoxia and th...

The southwestern margin of the South China Craton preserves a Late Permian to Early Triassic sedimentary succession, provenance which helps constrain magmatic history and tectonic evolution Paleo-Tethyan Orogen. In this study, we present new detrital zircon U-Pb age, trace element, Hf isotope whole-rock geochemical composition analyses from Lower Qingtianbao Formation, distinguish clastic rocks...

Abstract The Permian marine-terrestrial system of the North China block provides an exceptional window into evolution northern temperate ecosystems during critical transition from icehouse to greenhouse following late Paleozoic ice age (LPIA). Despite many studies on its rich hydrocarbon reserves and climate-sensitive fossil flora, uncertain temporal constraints correlations have hampered a tho...
