The Osmium Isotope Signature of Phanerozoic Large Igneous Provinces
Geophysical Monograph Series, Page 229-246., 2021 Exploring the links between Large Igneous Provinces and dramatic environmental impact
An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

Road and bridge construction across gypsum karst in England [PDF]
, 2002 Gypsum karst problems in the Permian and Triassic sequences of England have caused difficult conditions for bridge and road construction. In Northern England, the Ripon Bypass crosses Permian strata affected by active gypsum karst and severe subsidence ...

Upper Permian bryozoans of central East Greenland [PDF]
Bulletin of the Geological Society of Denmark, 2008 The bryozoan fauna in the Upper Permian Wegener Halvø, Ravnefjeld and Schuchert Dal formations, central East Greenland is of modest diversity, with only 15 genera identified. Bryozoans are most abundant in the Wegener Halvø Formation where they are important in the formation of carbonate buildups.

The fossil record of early tetrapods: worker effort and the end-Permian mass extinction [PDF]
, 2010 It is important to understand the quality of the fossil record of early tetrapods (Tetrapoda, minus Lissamphibia and Amniota) because of their key role in the transition of vertebrates from water to land, their dominance of terrestrial faunas for over ...

Lethaia, EarlyView., 2021 Biomineralization is a generic term used to indicate biological‐mediated mineral formation. In carbonate mineralization, nucleation of crystals can be: (1) controlled directly by the organisms, like in the skeletal formation of most metazoans; (2) induced by microbial communities, by indirect precipitation mediated by their metabolic activities; or (3)
