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 …

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

The first book to review all the evidence concerning both the dinosaur extinctions and all the
other major extinctions-of plant, animal, terrestrial, and marine life-in the history of life. All the …

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 …

For a long time, the Silurian was thought to represent a time of stable environmental
conditions in the greenhouse period that followed the Late Ordovician glaciation. During the …

Global sea-level fluctuated markedly during the early Silurian, probably as a result of the
waxing and waning of ice-sheets in the South American portion of Gondwana. The highest …

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 …

Ratios of stable carbon and oxygen isotopes in brachiopod shells (more than 370
specimens, esp. Atrypa reticularis) from the Silurian of Gotland, Sweden, have been …

The Ohesaare borehole, in the northern part of the Silurian Baltic Gulf, penetrates shallow
and deep shelf marlstones, limestones and dolostones. The Priekule borehole in the deep …

Graptoloid evolutionary dynamics show a marked contrast from the Ordovician to the
Silurian. Subdued extinction and origination rates during the Ordovician give way, during the …
