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

open access: goldScientific 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 ...

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

open access: greenNature 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]

open access: greenProc 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.

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

open access: goldCommunications 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.

High lineage survivorship across the end-Devonian Mass Extinction suggested by a remarkable new Late Devonian actinopterygian [PDF]

open access: gold, 2021
AbstractA mass extinction at the end of the Devonian is thought to have had a major influence on the evolution of actinopterygians (ray-finned fishes), which comprise half of living vertebrates. This extinction appears to have acted as a bottleneck, paring the early diversity of the group to a handful of survivors.

Land plant evolution and volcanism led to the Late Devonian mass extinction [PDF]

open access: gold, 2022
Abstract The evolution of land plants in terrestrial environments 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.

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

open access: yesScientific 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.

Modelling the Late Devonian Climate: Implications for evolution and extinction

open access: green, 2021
The Devonian period (419.2 - 358.9 Ma) was characterised by a warm greenhouse climate which transitioned towards glaciation throughout the Late Devonian. This period in Earth’s history was punctuated by repeated environmental and biotic crises. A common feature accompanying these events was widespread ocean anoxia, typically recorded in the geological ...

Ostracods Late Devonian mass extinction: the Schmidt quarry parastratotype (Kellerwald, Germany) [PDF]

open access: bronzeComptes Rendus de l'Académie des Sciences - Series IIA - Earth and Planetary Science, 1998
Abstract Sixty-eight ostracod species have been recognized (the benthonic one for the first time) close to the Frasnian/Famennian boundary in the Schmidt quarry parastratotype. In the Late Frasnian, ostracods belong to an assemblage of the Eifelian ecotype and to the Myodocopid ecotype.

A Late Devonian actinopterygian suggests high lineage survivorship across the end-Devonian mass extinction

open access: greenNature Ecology & Evolution, 2022
Many accounts of the early history of actinopterygians (ray-finned fishes) posit that the end-Devonian mass extinction had a major influence on their evolution. Existing phylogenies suggest this episode could have acted as a bottleneck, paring the early diversity of the group to a handful of survivors.
