Late Devonian global ostracod palaeobiogeography
Lethaia, 2017A 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 ...

The Xichong flora of Yunnan, China: diversity in late Mid Devonian plant assemblages
Over the past 10 years, significant progress has been made in our understanding of late Mid Devonian floras of Yunnan Province, China. Based on new collections and a restudy of existing specimens, most of the old taxa have been emended, and some new taxa

A complete insect from the Late Devonian period
Nature, 2012After 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 ...

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, 2003Acanthodian 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, 1993Abstract 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
