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

Neopterygian phylogeny: the merger assay [PDF]
Royal 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 ...

Phylogenetic analyses of ray-finned fishes (Actinopterygii) using collagen type I protein sequences
Royal Society Open Science, 2021 Ray-finned fishes (Actinopterygii) are the largest and most diverse group of vertebrates, comprising over half of all living vertebrate species. Phylogenetic relationships between ray-finned fishes have historically pivoted on the study of morphology ...

A phylogenomic perspective on the radiation of ray-finned fishes based upon targeted sequencing of ultraconserved elements [PDF]
, 2012 Ray-finned fishes constitute the dominant radiation of vertebrates with over 30,000 species. Although molecular phylogenetics has begun to disentangle major evolutionary relationships within this vast section of the Tree of Life, there is no widely ...

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