A new stem group echinoid from the Triassic of China leads to a revised macroevolutionary history of echinoids during the end-Permian mass extinction [PDF]

Royal Society Open Science, 2018
The Permian–Triassic bottleneck has long been thought to have drastically altered the course of echinoid evolution, with the extinction of the entire echinoid stem group having taken place during the end-Permian mass extinction. The Early Triassic fossil

Paleoclimate-induced stress on polar forested ecosystems prior to the Permian–Triassic mass extinction

Scientific Reports, 2022
The end-Permian extinction (EPE) has been considered to be contemporaneous on land and in the oceans. However, re-examined floristic records and new radiometric ages from Gondwana indicate a nuanced terrestrial ecosystem response to EPE global change ...

Characteristics of the temperature–pressure field evolution of Middle Permian system in the northwest of Sichuan Basin

Energy Exploration & Exploitation, 2018
The Sichuan Basin is one of the richest oil and gas basins in China. The Middle Permian units (the Qixia and Maokou Formations) in the northwest Sichuan Basin have great potential for gas exploration.

Evidence for multi-rifting in the Variscan–Alpine cycle transition: insights from the European western Southern Alps [PDF]

Solid Earth
We investigate the transition between the Paleozoic Variscan cycle and the Mesozoic–Cenozoic Alpine supercontinent cycle, both of which have played a pivotal role in shaping the central European–Mediterranean plate architecture.
