Late Devonian impacts

open access: yes, 2015
In 1970 the first hypothesis, which claimed that large meteorite landed in ocean at Frasnian/Famennian boundary and caused mass extinction was proposed. In Late Devonian deposits there are many potential impact evidences.

Late Devonian to Early Carboniferous palaeomagnetic poles from the Armorican Massif, France [PDF]

open access: yes, 1979
In order to test plate tectonic hypotheses for the Hercynian orogeny in western Europe, Late Devonian and Cambro-Ordovician redbeds and volcanics have been palaeomagnetically studied.

Stratigraphic distribution and systematic composition of the Middle-Upper Devonian placoderms (anti-archs) from Central Kazakhstan

open access: yesИзвестия высших учебных заведений: Геология и разведка, 2016
The stratigraphie distribution and systematic composition of the Middle-Upper Devonian remains of antiarchs from the sediments of Central Kazakhstan are analyzed. Central Kazakhstan ichthyofauna contains mainly endemic taxons of antiarchs.

Late Devonian and Carboniferous acritarch stratigraphy and paleogeography

open access: yes, 1986
Detailed analysis of literature on late Devonian and Carboniferous acritarchs learns that, up to now, late Devonian acritarch zonation has been proposed only for Algeria, U.S.A. and Belgium.

Rehamnia (Lycopodiophyta), a new enigmatic Late Devonian plant from Morocco

open access: yes, 2021
Rehamnia michardis Oukassou and Naugolnykh, gen. et sp. nov. is described from the Late Famennian of the Foum El Mejez area (Northern Rehamna, Moroccan Meseta). This is the first record of Late Devonian plant from the Rehamna Hercynian massif.

The Complete Mitogenome of the Estuarine Clam Potamocorbula amurensis (Corbulidae, Myida) and Its Implications for Phylogeny and Adaptation

open access: yesEcology and Evolution, Volume 16, Issue 7, July 2026.
This study reports the first complete mitogenome of the estuarine clam Potamocorbula amurensis, revealing its phylogenetic position as a sister group to the Myidae–Dreissenidae clade. Molecular dating indicates a Middle Jurassic divergence, and positive selection was detected in the nad5 gene, suggesting mitochondrial adaptations to osmotic stress in ...
