The Dermal Skeleton of Stem-Actinopterygian Moythomasia durgaringa and Its Implications for the Nature of the Ancestral Osteichthyan. [PDF]
J MorpholThe figure presents a model of Moythomasia and a schematic histological model illustrating the internal structure and features of the cranial bones. These include bone (brown), osteocyte spaces (red), spheritic bone (light brown), osteon spaces (orange), dentine and canaliculi (green), pulp canal (yellow), ganoine (gray), arrested growth lines (dashed ...

A new origin of the 'modern' lungfish dentition revealed by taxonomic overlap between Devonian and Carboniferous dipnoans. [PDF]
PeerJLungfishes (Dipnoi, Sarcopterygii) initially radiated in the Early Devonian, and reached the apogee of their diversity during this period, especially with regard to their dentitions.

Turning Red to Green Repeatedly: Ancestral LWS Duplications Drive Convergent Visual Tuning in Teleost Fishes. [PDF]
Mol EcolABSTRACT Photopigments, formed by an opsin protein bound to a light‐sensitive chromophore, underlie vertebrate vision. Long‐wavelength–sensitive (LWS) opsins mediate red‐light detection, and most teleosts retain a single functional LWS1. A shorter‐shifted green‐sensitive paralog (LWS2) is found only in a few lineages.

Investigating a Devonian vertebrate assemblage with synchrotron microtomography of coprolites. [PDF]
Sci RepFossilised faeces (coprolites) are a unique source of information as they record palaeontological evidence of animal behaviour (autecology) as well as interactions between extinct organisms and their environment (synecology).

Bony fish genomes: Status and gaps. [PDF]
J Fish BiolAbstract Bony fish constitute an exceptionally species‐rich group of aquatic vertebrates, comprising more than 95% of all living fish. The adaptive processes on the diversity of environments they inhabit make them a highly diverse group from taxonomic, morphological and evolutionary standpoints.

A new coelacanth (Actinistia, Sarcopterygii) from the Early Triassic of Anhui, China. [PDF]
Sci RepCoelacanths (e.g., Latimeria) are a curious group of sarcopterygian fishes that survive over hundreds of millions of years and are important in evolutionary biology.

Life history and ossification patterns in Miguashaia bureaui reveal the early evolution of osteogenesis in coelacanths [PDF]
PeerJ, 2022 The study of development is critical for revealing the evolution of major vertebrate lineages. Coelacanths have one of the longest evolutionary histories among osteichthyans, but despite access to extant representatives, the onset of their weakly ...

A fresh look at Cladarosymblema narrienense, a tetrapodomorph fish (Sarcopterygii: Megalichthyidae) from the Carboniferous of Australia, illuminated via X-ray tomography [PDF]
PeerJ, 2021 Background The megalichthyids are one of several clades of extinct tetrapodomorph fish that lived throughout the Devonian–Permian periods. They are advanced “osteolepidid-grade” fishes that lived in freshwater swamp and lake environments, with some taxa ...
