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 ...

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 ...
