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

Rhipidistians (Sarcopterygii) from the Hunter Siltstone (Late Famennian) near Grenfell, NSW, Australia [PDF]
Rhipidistian sarcopterygian fishes (Dipnomorpha + Tetrapodomorpha) are well represented in the upper levels of the Hunter Siltstone (latest Famennian) near Grenfell. New South Wales (NSW), Australia.

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 ...

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

Today, the only living genus of coelacanth, Latimeria is represented by two species along the eastern coast of Africa and in Indonesia. This sarcopterygian fish is nicknamed a "living fossil", in particular because of its slow evolution.

Habitat of early stegocephalians (Chordata, Vertebrata, Sarcopterygii): a little saltier than most paleontologists like? [PDF]
A controversy on the degree of marine influence in the paleoenvironments represented by many Paleozoic stegocephalian-bearing fossiliferous localities has persisted for decades.

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

Structural and functional divergence of growth hormone-releasing hormone receptors in early sarcopterygians: lungfish and Xenopus. [PDF]
The evolutionary trajectories of growth hormone-releasing hormone (GHRH) receptor remain enigmatic since the discovery of physiologically functional GHRH-GHRH receptor (GHRHR) in non-mammalian vertebrates in 2007.

The giant cretaceous Coelacanth (Actinistia, Sarcopterygii) Megalocoelacanthus dobiei Schwimmer, Stewart & Williams, 1994, and its bearing on Latimerioidei interrelationships. [PDF]
We present a redescription of Megalocoelacanthus dobiei, a giant fossil coelacanth from Upper Cretaceous strata of North America. Megalocoelacanthus has been previously described on the basis of composite material that consisted of isolated elements ...
