Distributional patterns of ?Mawsoniidae (Sarcopterygii: Actinistia) [PDF]
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 conservation of intronic sequences was studied in the mitochondrial solute carrier (SLC25A*) genes of Zebrafish, Chicken, Mouse and Human. These genes are homologous and the coding sequences have been well conserved throughout Vertebrates, but the ...

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).
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 ...

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.

The cranial endocast of Dipnorhynchus sussmilchi (Sarcopterygii: Dipnoi) and the interrelationships of stem-group lungfishes [PDF]
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 ...

First record ofPorolepis(Sarcopterygii; Porolepiformes) from eastern Gondwana
Porolepiformes (Sarcopterygii) are poorly represented in the Devonian of Australia and eastern Gondwana as a whole. New cosmine-covered lower jaws from the Mulga Downs Group, western New South Wales (?Pragian–Emsian or Eifelian), represent the first occurrence of Porolepis in Australia, a genus formerly known exclusively from the Northern Hemisphere ...

Ecomorphological change in lobe-finned fishes (Sarcopterygii): disparity and rates [PDF]
Patterns of vertebrate cranial/post-cranial trait diversification are not well-understood. Two ecological hypotheses, the ‘head-first’ model and the ‘stages’ model, predict the ordered decoupling of cranial/post-cranial ecomorphological ...

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
