The late Frasnian (Upper Devonian) Kellwasser Crisis
2005Detailed investigations of sequences containing the Kellwasser Bio-event near the Frasnian-Famennian boundary demonstrate a stepwise character of influences on different groups of organisms over a time span of more than 1 my. Therefore the term Kellwasser Crisis (KW Crisis) is introduced. Extraordinary episodes of the KW Crisis, like e.g.

Late Devonian syntaxis in the Northern Appalachian orogen
Geological Society, London, Special PublicationsAbstract The pre-accretionary shapes of cratonic margins form successions of promontories and re-entrants inherited from the rifting of supercontinents. In accretionary orogens, the extent of deformation related to a collision with a continent characterized by an irregular margin is obfuscated through the ...

Biogeography of late Silurian and devonian rugose corals
Palaeogeography, Palaeoclimatology, Palaeoecology, 1977Abstract Three marine benthic faunal realms can be recognized in the Early and Middle Devonian. The Eastern Americas Realm consisted of most of the eastern half of North America and South America north of the Amazon. This realm extended in a southwest direction from the Devonian equator to approximately 35°S and was an isolated epicontinental sea ...

OBLIQUITY-PACING OF THE LATE DEVONIAN MASS EXTINCTION EVENT
2017The Late Devonian envelops one of Earth’s “Big Five” mass extinction events at the Frasnian Famennian boundary (374Ma). Environmental change across the extinction severely affected Devonian reefbuilders, besides many other forms of marine life. Despite the biosphere shake-up, cause-and-effect chains leading to extinction remain poorly constrained. This
