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

Nature 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.

Microtektites and Mass Extinctions: Evidence for a Late Devonian Asteroid Impact

Science, 1992
Glass spherules, similar to microtektites, have been found near the Frasnian-Famennian boundary (F/F) (Upper Devonian) at Senzeilles, Belgium, contemporaneous with one of the largest marine mass extinctions of the Phanerozoic. These spherules exhibit a wide range of compositions and display teardrop, dumbbell, and compound morphologies analogous to ...

Oxic facies and the Late Devonian mass extinction, Canning Basin, Australia

Geology, 2014
The close association of anoxic or dysoxic sedimentary rocks and the major Late Devonian (Frasnian–Famennian) mass extinction has focused considerable attention on anoxia as the major cause or as a major factor in a multicausal scenario. The record of the Late Devonian biotic crisis in the well-known reef complexes of northwestern Australia (Canning ...

Onshore expansion of benthic communities after the Late Devonian mass extinction

Lethaia, 2013
Buatois, L.A., Angulo, S. & Mangano, G.M. 2013: Onshore expansion of benthic communities after the Late Devonian mass extinction. Lethaia, Vol. 46, pp. 251–261. A detailed ichnological analysis of the Upper Devonian–Lower Mississippian Bakken Formation of sub-surface Saskatchewan and the partially coeval Exshaw Formation of Alberta indicates the ...

Environmentally controlled phyletic evolution, blindness and extinction in Late Devonian tropidocoryphine trilobites

Lethaia, 1989
The Middle and Upper Devonian carbonate succession of the Montagne Noire, Southern France has been precisely zoned by an unbroken sequence of conodont zones. Stratigraphic control is excellent, and has allowed evolutionary changes in tropidocoryphine trilobites, which occur throughout the succession, to be directly established. The tropidocoryphine had

Late Silurian—early Devonian biogeography, provincialism, evolution and extinction

Philosophical Transactions of the Royal Society of London. B, Biological Sciences, 1985
There is increasing marine to continental regression from the latest Silurian until the latter half of the early Devonian, when a major transgressive trend is initiated which achieves its maximum in the later middle Devonian and late Devonian. Data suggest a relatively high climatic gradient, but no evidence favouring continental, sea-level glaciation ...

Encrustation patterns on post-extinction early Famennian (Late Devonian) brachiopods from Russia

Historical Biology, 2013
A 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

2005
Abstract 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, 1988
The 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, 2013
Abstract 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 ...
