Accelerated mass extinction in an isolated biota during Late Devonian climate changes

Scientific Reports, 2021
The fossil record can illuminate factors that contribute to extinction risk during times of global environmental disturbance; for example, inferred thermal tolerance was an important predictor of extinction during several mass extinctions that ...

The fate of the homoctenids (Tentaculitoidea) during the Frasnian-Famennian mass extinction (Late Devonian) [PDF]

Geobiology, 2006
The homoctenids (Tentaculitoidea) are small, conical-shelled marine animals which are amongst the most abundant and widespread of all Late Devonian fossils.

Early sarcopterygian morphological disparity through the Devonian-Carboniferous crisis [PDF]

Scientific Reports
Major morphological adaptations characterized the early evolutionary history of sarcopterygians during the Devonian (419–359 Ma) and the Carboniferous (359–299 Ma), punctuated by environmental changes and biodiversity crises.

Timing and pacing of the Late Devonian mass extinction event regulated by eccentricity and obliquity [PDF]

Nature Communications, 2017
Understanding of Late Devonian mass extinction mechanisms is poor due to imprecise stratigraphies. Here, using cyclostratigraphic techniques, the authors present a global orbitally-calibrated chronology and reveal the key role of astronomically-forced ...

Niche conservatism and ecological change during the Late Devonian mass extinction. [PDF]

Proc Biol Sci, 2023
Studies of the fossil record can inform our understanding of not only the causes of mass extinctions, but also their effects on biodiversity, ecology and evolution. Here, we examine regional-scale ecological changes resulting from a Late Devonian mass extinction event using brachiopod fossil assemblages from the Appalachian Basin.

Enhanced continental weathering and its marine environmental effects in the late Devonian: Constraints from strontium isotopes of carbonate rocks in South China

地质科技通报, 2022
The Frasnian-Famennian extinction in the late Devonian was one of the largest mass extinction during Earth's history, which was believed to be caused by the plant landing-indued intensification of terrestrial chemical weathering and the consequent ...

High-Resolution Late Devonian Magnetostratigraphy From the Canning Basin, Western Australia: A Re-Evaluation

Frontiers in Earth Science, 2021
Late Devonian time was a period of rapid upheaval in the Earth system, including climate change, sea level changes, widespread ocean anoxia, and the Frasnian-Famennian mass extinction; the cause(s) of these changes remain(s) uncertain.

The expansion of land plants during the Late Devonian contributed to the marine mass extinction

Communications Earth & Environment, 2023
The evolution and expansion of land plants brought about one of the most dramatic shifts in the history of the Earth system — the birth of modern soils — and likely stimulated massive changes in marine biogeochemistry and climate.

Mercury Anomalies Link to Extensive Volcanism Across the Late Devonian Frasnian–Famennian Boundary in South China

Frontiers in Earth Science, 2021
The Late Devonian Frasnian–Famennian (F–F) mass extinction has been long-time debated by non-volcanic causes, extra-terrestrial impacts, and large igneous province (LIP) eruptions.

Functional consequences of Palaeozoic reef collapse

Scientific Reports, 2022
Biogenic reefs have been hotspots of biodiversity and evolutionary novelty throughout the Phanerozoic. The largest reef systems in Earth’s history occurred in the Devonian period, but collapsed during the Late Devonian Mass Extinction.
