Late Devonian global ostracod palaeobiogeography

Lethaia, 2017
A global Late Devonian ostracod database is constructed, incorporating new materials from South China and Northwest China. Four palaeobiogeographical units (Cathaysia, North America, Europe and peri-Gondwana) are recognized during the Frasnian and five palaeobiogeographical units (Cathaysia, North America, Europe, Siberia and Australia) in the ...

A complete insect from the Late Devonian period

Nature, 2012
After terrestrialization, the diversification of arthropods and vertebrates is thought to have occurred in two distinct phases, the first between the Silurian and the Frasnian stages (Late Devonian period) (425-385 million years (Myr) ago), and the second characterized by the emergence of numerous new major taxa, during the Late Carboniferous period ...

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.

Late Devonian acanthodians from Colombia

Journal of South American Earth Sciences, 2003
Acanthodian remains occur in micaceous siltstone lenses (presumed to have been deposited during a marine incursion) in the Cuche Formation (?Frasnian) of northeast Colombia. The acanthodians are represented by patches of scales from climatiidid Nostolepis sp. cf. N. gatijensis and a fin spine and scales from a new diplacanthid.

Climate of the Late Devonian to Triassic

Palaeogeography, Palaeoclimatology, Palaeoecology, 1993
Abstract Remarkable changes are apparent in climate during Late Devonian-Triassic times. Mostly the climate was rather different from the present. The faunas and floras offer much evidence for understanding the climate but, in turn, understanding the palaeogeography of the faunas and floras is dependent on understanding the climate and the changes in

Palaeobiogeography of Famennian (Late Devonian) bryozoans

Palaeogeography, Palaeoclimatology, Palaeoecology, 2010
Abstract Bryozoans were widely distributed in marine habitats of the Famennian (Late Devonian) worldwide. This time interval was marked by gradual change in taxonomic composition of bryozoan faunas, which were insignificantly affected by global events (Upper Kellwasser, Handerberg). Distribution of bryozoan faunas was controlled by intrinsic factors (

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 ...

Biogeography of Late Silurian and Devonian acritarchs and prasinophytes

Review of Palaeobotany and Palynology, 1997
Abstract The palaeobiogeography of Late Silurian-Devonian acritarch and prasinophyte microfloras is assessed using qualitative data, similarity indexes and cluster analysis. Based on the recent palaeogeographic reconstructions, the northwards movement of Gondwana initiated during the Ludlovian with the progressive narrowing of the Rheic ocean ...
