Progress, problems and prospects: An overview of the Guadalupian Series of South China and North America
Abstract The Guadalupian Epoch is marked by the formation of the Pangean supercontinent,
global sea-level change, rifting and drifting of the Cimmerian continents, formation of large …

The Smithian/Spathian boundary (late Early Triassic): A review of ammonoid, conodont, and carbon-isotopic criteria
The transition from the Smithian substage to the Spathian substage of the Olenekian stage
of the late Early Triassic was a critical time marked by a series of biological and …

The permian period
The supercontinent Pangea completes its assembly and moves north during the Permian.
The 47-million-year-long period begins with a great ice age and ends with the Earth's …

The terrestrial end-Permian mass extinction in the paleotropics postdates the marine extinction
The end-Permian mass extinction was the most severe ecological event during the
Phanerozoic and has long been presumed contemporaneous across terrestrial and marine …

A sudden end-Permian mass extinction in South China
Previous studies of the end-Permian mass extinction have established that it was
geologically rapid, but condensed sections have made it difficult to establish the exact timing …

Siberian Trap volcanism, global warming and the Permian-Triassic mass extinction: New insights from Armenian Permian-Triassic sections
Permian-Triassic boundary sections from Armenia were studied for carbon isotopes of
carbonates as well as oxygen isotopes of conodont apatite in order to constrain the global …

[HTML][HTML] New high precision U-Pb ages and Hf isotope data from the Karoo large igneous province; implications for pulsed magmatism and early Toarcian …
To better constrain the age and duration of the magmatism associated with the Karoo large
igneous province (LIP), we present new U-Pb ID-TIMS dates and εHf values from …

New geochemical and palaeontological data from the Permian-Triassic boundary in the South African Karoo Basin test the synchronicity of terrestrial and marine …
The end-Permian mass extinction (EPME) is widely recognised as the largest mass
extinction in Phanerozoic history. In marine strata the main extinction event is well …

Two distinct episodes of marine anoxia during the Permian-Triassic crisis evidenced by uranium isotopes in marine dolostones
The end-Permian mass extinction (EPME; ca. 251.94 Ma) is the most severe mass extinction
in the geological record. Detailed paleobiological investigations show a very rapid EPME …
