Lung evolution in vertebrates and the water-to-land transition

open access: yeseLife, 2022
A crucial evolutionary change in vertebrate history was the Palaeozoic (Devonian 419–359 million years ago) water-to-land transition, allowed by key morphological and physiological modifications including the acquisition of lungs. Nonetheless, the origin

Diversity of chondrostean fish Coccolepis from the Late Jurassic Solnhofen Archipelago, Southern Germany [PDF]

open access: yesActa Palaeontologica Polonica, 2021
Late Jurassic marine vertebrates are extraordinarily well preserved in several Plattenkalk Lagerstätten in central Europe. Among them, the Solnhofen Archipelago has yielded the very rare fish Coccolepis bucklandi, which was the first fossil ...

A new specimen of Birgeria liui (Osteichthyes, Actinopterygii) from the Longobardian (Ladinian, Middle Triassic) of Xingyi, Guizhou Province, South China [PDF]

open access: yesResearch & Knowledge, 2017
Birgeria was one of the largest carnivorous ishes from the Triassic, spanning almost the entire period and, with an almost cosmopolitan distribution. Birgeria liui was originally described based on the incomplete holotype from the Middle Triassic marine ...

Unappreciated Cenozoic ecomorphological diversification of stem gars revealed by a new large species [PDF]

open access: yesActa Palaeontologica Polonica, 2022
The evolutionary history of gars, an ancient group of ray-finned fishes, is excellently documented in the fossil record. These fishes are notable for how little the anatomy of extant species differs from that of their earliest known relatives from ...

Neopterygian phylogeny: the merger assay [PDF]

open access: yesRoyal Society Open Science, 2018
The phylogenetic relationships of the recently described genus †Ticinolepis from the Middle Triassic of the Monte San Giorgio are explored through cladistic analyses of the so far largest morphological dataset for fossil actinopterygians, including ...

Les « ichtyolites » (Actinopterygii) de la collection Jean-Baptiste Beurard (1745–1835) : intérêt historique et redécouverte de la série type d’Armigatus brevissimus (Blainville, 1818) du Cénomanien du Liban

open access: yesBSGF - Earth Sciences Bulletin, 2021
Cet article souligne le rôle Jean-Baptiste Beurard dans l’histoire de la paléoichtyologie. Ancien chanoine de la cathédrale de Toul, il trouva après les affres des débuts de la Révolution un emploi d’agent du gouvernement attaché à l’administration des ...

A Hiatus Obscures the Early Evolution of Modern Lineages of Bony Fishes

open access: yesFrontiers in Earth Science, 2021
About half of all vertebrate species today are ray-finned fishes (Actinopterygii), and nearly all of them belong to the Neopterygii (modern ray-fins). The oldest unequivocal neopterygian fossils are known from the Early Triassic.

Feeding convergence among ray-finned fishes: Teeth of the herbivorous actinopterygians from the latest Permian of East European Platform, Russia [PDF]

open access: yesActa Palaeontologica Polonica, 2020
unique functional adaptation to herbivory within early ray-finned fishes is exemplified by the late Permian actinopterygians within the family Eurynotoidiidae with policuspid teeth strongly modified with respect to the primitive actinopterygian ...

Integrating multi-origin expression data improves the resolution of deep phylogeny of ray-finned fish (Actinopterygii) [PDF]

open access: yes, 2012
The actinopterygians comprise nearly one-half of all extant vertebrate species and are very important for human well-being. However, the phylogenetic relationships among certain groups within the actinopterygians are still uncertain, and debates about ...
