Encrustation patterns on post-extinction early Famennian (Late Devonian) brachiopods from Russia
Historical Biology, 2013A study of patterns of episkeletobiont encrustation on the shells of two early Famennian brachiopods, Cyrtospirifer zadonicus and Ripidiorhynchus huotinus from Russia, revealed assemblages comprising seven skeletonised encruster taxa. The assemblages are dominated by spirorbiform microconchids, followed by cornulitids.

Chapter 3 Modelling late devonian extinction hypotheses
2005Abstract Modelling the conditions of extinction hypotheses can lead to the discernment of the critical observations that must be made in order to definitively test those hypotheses. Models considered here are based upon the beginning ning assumption that the end-Frasnian biodiversity crisis was triggered in large part by pulses of global cooling ...

The Late Devonian extinction event: evidence for abrupt ecosystem collapse
Paleobiology, 1988The Late Devonian extinction event was not geologically “instantaneous,” in that extinctions during the epoch are not concentrated into a single sharp pulse at the end of the Frasnian. Extinction rates are elevated for a period of at least 2 to 4 m.y.

A forest fire and soil erosion event during the Late Devonian mass extinction
Palaeogeography, Palaeoclimatology, Palaeoecology, 2013Abstract The Late Devonian mass extinction occurred in a stepwise manner and culminated close to the Frasnian–Famennian (F–F) boundary (372 million years ago). Organic-molecular indices from marine sedimentary rocks at the Sinsin section, Belgium, indicate that the sequence of combustion of land vegetation, soil erosion, and anoxia–euxinia occurred ...

No geochemical evidence for an asteroidal impact at late Devonian mass extinction horizon
Nature, 1984One way to test the proposed causal relationship between mass biotic extinction and asteroidal impact is to search for the geochemical signature of such an event at additional mass extinction horizons other than the Cretaceous–Tertiary (K–T) boundary. We report here the results of an extensive search for an indium (Ir) anomaly across the late Devonian ...

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

Biotic recovery from the Late Devonian F-F mass extinction event in China
Science in China Series D: Earth Sciences, 2002The Frasnian-Famennian (F-F) mass extinction is one of the five great extinctions of marine life during the Phanerozoic. The F-F event killed most of the Devonian reefs, the characteristic Devonian corals, stromatoporoids, bryozoans, nearly all tentaculites, a few superfamilies of brachiopods, such as Atrypacea and Pentameracea and some important ...

Causes of the great mass extinction of marine organisms in the Late Devonian
Oceanology, 2016The second of the five great mass extinctions of the Phanerozoic occurred in the Late Devonian. The number of species decreased by 70–82%. Major crises occurred at the Frasnian–Famennian and Devonian–Carboniferous boundary. The lithological and geochemical compositions of sediments, volcanic deposits, impactites, carbon and oxygen isotope ratios ...

Palaeogeography, Palaeoclimatology, Palaeoecology, 2001
Abstract Application of the lag-time multiple impacts hypothesis [Poag, 1997b. Palaios 12, 582–590; Poag et al., 2001. Columbia Univ. Press] to the Late Devonian leads to the prediction that the Frasnian–Famennian pulsed extinctions were triggered by a rapid drop in global temperature that followed an impact-produced anomalous warm interval, which ...
