Distributional patterns of ?Mawsoniidae (Sarcopterygii: Actinistia) [PDF]

open access: yesAnais Da Academia Brasileira De Ciencias, 2014
Mawsoniidae are a fossil family of actinistian fish popularly known as coelacanths, which are found in continental and marine paleoenvironments. The taxon is considered monophyletic, including five valid genera (Axelrodichthys, Chinlea, Diplurus ...

A new coelacanth (Actinistia, Sarcopterygii) from the Early Triassic of Anhui, China [PDF]

open access: yesScientific Reports
Coelacanths (e.g., Latimeria) are a curious group of sarcopterygian fishes that survive over hundreds of millions of years and are important in evolutionary biology.

The Dermal Skeleton of Stem-Actinopterygian Moythomasia durgaringa and Its Implications for the Nature of the Ancestral Osteichthyan. [PDF]

open access: yesJ Morphol
The 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 high latitude Gondwanan species of the Late Devonian tristichopterid Hyneria (Osteichthyes: Sarcopterygii).

open access: yesPLoS ONE, 2023
We describe the largest bony fish in the Late Devonian (late Famennian) fossil assemblage from Waterloo Farm near Makhanda/Grahamstown, South Africa. It is a giant member of the extinct clade Tristichopteridae (Sarcopterygii: Tetrapodomorpha) and most ...

The first virtual cranial endocast of a lungfish (sarcopterygii: dipnoi).

open access: yesPLoS ONE, 2014
Lungfish, or dipnoans, have a history spanning over 400 million years and are the closest living sister taxon to the tetrapods. Most Devonian lungfish had heavily ossified endoskeletons, whereas most Mesozoic and Cenozoic lungfish had largely ...

A new origin of the ‘modern’ lungfish dentition revealed by taxonomic overlap between Devonian and Carboniferous dipnoans [PDF]

open access: yesPeerJ
Lungfishes (Dipnoi, Sarcopterygii) initially radiated in the Early Devonian, and reached the apogee of their diversity during this period, especially with regard to their dentitions.

Investigating a Devonian vertebrate assemblage with synchrotron microtomography of coprolites [PDF]

open access: yesScientific Reports
Fossilised 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]

open access: yesJ Fish Biol
Abstract 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.

Histology of juvenile skin of Lepidosiren paradoxa Fitzinger, 1837 (Sarcopterygii, Dipnoi) [PDF]

open access: yesAnais da Academia Brasileira de Ciências, 2019
: The skin of three juvenile Lepidosiren paradoxa specimens was examined. The epidermis was composed of a polystratified epithelium resting on a basement membrane, including mucus-secreting cells, and a cuticle of mucopolysaccharides on the surface.
