Distributional patterns of ?Mawsoniidae (Sarcopterygii: Actinistia) [PDF]
Anais da Academia Brasileira de Ciências, 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 ...

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

The cranial endocast of Dipnorhynchus sussmilchi (Sarcopterygii: Dipnoi) and the interrelationships of stem-group lungfishes [PDF]
PeerJ, 2016 The first virtual cranial endocast of a lungfish from the Early Devonian, Dipnorhynchus sussmilchi, is described. Dipnorhynchus, only the fourth Devonian lungfish for which a near complete cranial endocast is known, is a key taxon for clarifying ...

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 ...

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 ...

Los dipnoos (Sarcopterygii, Osteichthyes) del Mesozoico de Argentina
, 2023 Los dipnoos conforman un clado dentro de los sarcopterigios con un registro fósil que abarca desde el Devónico Temprano hasta el presente. Durante el Paleozoico los dipnoos eran mayormente marinos y su distribución cosmopolita. Sin embargo, a partir del Mesozoico habitan únicamente cuerpos de aguas continentales y su distribución comienza a limitarse ...

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 ...

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
