A Late Devonian actinopterygian suggests high lineage …
WEBNov 17, 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...
From obscurity to dominance: Tracking the rapid evolutionary …
WEBJul 22, 2013 · The extinction that ended the Devonian Era 359 million years ago created opportunities quickly exploited by a formerly rare and unremarkable group of fish that went on to become—in terms of the sheer number of species—the most successful vertebrates (backboned animals) on the planet today: the ray-finned fish.
The oldest Devonian circumpolar ray-finned fish?
WEBMar 10, 2021 · Actinopterygians (ray-finned fishes) are the most diverse group of living fishes, but have a sparse Devonian fossil record restricted to low palaeolatitudes. Here we report a new actinopterygian from the Paraná Basin of Brazil, which occupied a circumpolar position in the Palaeozoic.
The early evolution of ray-finned fishes - Wiley Online Library
WEBRay-fins are relatively diverse in the aftermath of the end-Devonian Hangenberg event (Fig. 4A), representing a striking contrast to other groups such as ‘placoderms’ and piscine sarcopterygians that were either eradicated or never recovered to Devonian levels.

WEBRay-finned fishes likely evolved in the Silurian (Zhu et al., 2009) with the crown group originating close to the Devonian–Carboniferous boundary (Giles et al., 2017), but diversity dynamics throughout the Palaeozoic are poorly understood due to the limited number of studies utilising occurrence-based datasets.
