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 ...

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.

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.

Middle/Late Devonian Phoebodontbased ichthyolith zonation

Geobios, 1995
Abstract A subdivision of the upper part of the Devonian (varcus through praesulcata conodont zones) into six ichthyolith zones is proposed. The zonation is based on the stratigraphic ranges of elasmobranch teeth from the pelagic facies of Central and Eastern Europe. Species of the genus Phoebodus were chosen as index taxa.
