Phylogenetic analyses of ray-finned fishes (Actinopterygii) using collagen type I protein sequences
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 ...

Intestinal Microbiome Richness of Coral Reef Damselfishes (Actinopterygii: Pomacentridae)
Fish gastro-intestinal system harbors diverse microbiomes that affect the host's digestion, nutrition, and immunity. Despite the great taxonomic diversity of fish, little is understood about fish microbiome and the factors that determine its structure ...

A primitive actinopterygian braincase from the Tournaisian of Nova Scotia [PDF]
The vertebrate fossil record of the earliest Carboniferous is notoriously poorly sampled, obscuring a critical interval in vertebrate evolution and diversity.

A giant dapediid from the Late Triassic of Switzerland and insights into neopterygian phylogeny [PDF]
A new Triassic neopterygian is described on the basis of a large three-dimensional neurocranium from the Rhaetian (Late Triassic) of the Kössen Formation (Schesaplana, Grisons, Switzerland).

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

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

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