The end-Triassic mass extinction event [PDF]
The end-Triassic mass extinction event, one of the five biggest in the Phanerozoic, is clearly marked in the marine realm by the almost total extinction of the ammonites, final disappearance of the conodonts, collapse of the reef ecosystem, and substantial changes in other groups.

Late Frasnian Mass Extinction: Conodont Event Stratigraphy, Global Changes, and Possible Causes [PDF]
Several abrupt changes in conodont biofacies are documented to occur synchronously at six primary control sections across the Frasnian-Famennian boundary in Euramerica. These changes occurred within a time-span of only about 100,000 years near the end of

The Cleveland Basin of Yorkshire, UK, hosts one of the most iconic Lower Jurassic rock successions for studying the Toarcian Oceanic Anoxic Event and the associated mass extinction, yet our understanding of the subsequent recovery is limited.

Crocodilians and their allies have survived several mass extinction events. However, the impact of the K-Pg mass extinction event on crocodylomorphs is considered as minor or non-existent although other clades of archosaurs, e.g., non-avian dinosaurs and

Multi-variate model of T cell clonotype competition and homeostasis
Diversity of the naive T cell repertoire is maintained by competition for stimuli provided by self-peptides bound to major histocompatibility complexes (self-pMHCs).

Bioindicators of severe ocean acidification are absent from the end-Permian mass extinction
The role of ocean acidification in the end-Permian mass extinction is highly controversial with conflicting hypotheses relating to its timing and extent.

The Cretaceous–Paleogene (K–Pg) mass extinction was geologically instantaneous, causing the most drastic extinction rates in Earth’s History. The rapid species losses and environmental destruction from the Chicxulub impact at 66.02 Ma made the K–Pg the ...
