Following the Cambrian Explosion and the appearance in the fossil record of most animal
phyla associated with a range of new body plans, the Ordovician and Silurian periods …

Recent analyses of Sepkoski's genus-level compendium show that only three events form a
statistically separate class of high extinction intensities when only post-Early Ordovician …

A new ecological-severity ranking of the major Phanerozoic biodiversity crises is proposed
in which the Capitanian crisis is ranked lesser than the Frasnian (Late Devonian) but greater …

Mass extinction events affect a wide breadth of ecosystems and are one of the major driving
mechanisms behind evolution, origination, and diversification of taxa. Such dramatic …

Abstract Abiotic, Bioinduced and Biocontrolled carbonates are process-based sediment
categories. They successively reflect increasing levels of biotic control over carbonate …

Abstract Earliest Triassic microbialites (ETMs) and inorganic carbonate crystal fans formed
after the end-Permian mass extinction (ca. 251.4 Ma) within the basal Triassic Hindeodus …

About 500 samples from 11 Ordovician sections in South China have been analysed for
their δ13Ccarb composition. Four sections are located in the Yangtze platform region, the …

Widespread development of microbialites characterizes the substrate and ecological
response during the aftermath of two of the 'big five'mass extinctions of the Phanerozoic …

The present study reviews the main geochemical, sedimentological, and paleontological
events associated with one of the largest perturbations in the Phanerozoic carbon cycle, the …

A succession of 26 conodont zones and 63 successive subzones and conodont faunas have
been identified in the exposed latest Landovery to latest Ludlow strata of Gotland, Sweden …
