Fossil discoveries and improved phylogenies, have greatly improved our understanding of the origin of tetrapods, making it possible to reconstruct sequences of character change leading to tetrapod morphologies, and to tentatively identify the genetic basis for some of these changes,. However, progress has centred on the upper part of the Tetrapodomorpha which is occupied by Devonian tetrapods such as Acanthostega,, and Ichthyostega. Few advances have been made in improving our understanding of… Expand
An exceptional Devonian fish from Australia sheds light on tetrapod origins
TLDR
New observations from the most complete, acid-prepared Devonian tetrapodomorph fish yet discovered, Gogonasus are presented, which was previously placed just crownward of Kenichthys and rhizodontids, the most primitive taxa on the tetrapOD lineage. Expand
Baraminological analysis of Devonian and Carboniferous tetrapodomorphs
According to evolutionary theory, the origin of tetrapods (or limbed vertebrates) from a fish-like ancestor during the Devonian Period was one of the major events in the history of life. DevonianExpand
Ontogenetic evidence for the Paleozoic ancestry of salamanders
TLDR
Comparison of patterns of larval development in Paleozoic and modern amphibians provides a means to test previous phylogenies based primarily on adult characteristics and proves to be highly informative in the case of the origin of salamanders. Expand
The emergence of early tetrapods
Abstract Study of Devonian tetrapods and their relatives spanning the so-called ‘fish–tetrapod’ transition has expanded almost exponentially in the last 15 years or so. This evolutionary event is nowExpand
A Devonian tetrapod-like fish reveals substantial parallelism in stem tetrapod evolution
TLDR
A large, lobe-finned fish from the Late Devonian of China disrupts previously accepted stem-tetrapod phylogeny and reveals parallel evolution within the lineage, suggesting that ecological diversity and biogeographical provinciality in the tetrapod stem group have been underestimated. Expand
Non-marine palaeoenvironment associated to the earliest tetrapod tracks
TLDR
A new palaeoenvironmental interpretation of the track-bearing interval from Zachełmie is presented, showing that it represents a succession of ephemeral lakes with a restricted and non-marine biota, rather than a marginal marine environment as originally thought. Expand
Bones, molecules, and crown- tetrapod origins
The timing of major events in the evolutionary history of early tetrapods is discussed in the light of a new cladistic analysis. The phylogenetic implications of this are compared with those of theExpand
A primitive fish close to the common ancestor of tetrapods and lungfish
TLDR
Styloichthys from the Lower Devonian of China bridges the morphological gap between stem-group sarcopterygians (Psarolepis and Achoania) and basal tetrapodomorphs/basal dipnomorphs and provides information that will help in the study of the relationship of early sarcoperygians, and which will also help to resolve the tetrapods–lungfish divergence into a documented sequence of character acquisition. Expand
The earliest known stem-tetrapod from the Lower Devonian of China.
TLDR
The enlargement of the cerebral hemispheres and the possible presence of the pars tuberalis in this stem-tetrapod indicate that some important brain modifications related to terrestrial life had occurred at the beginning of the tetrapod evolution, much earlier than previously thought. Expand
THE ORIGIN AND EARLY RADIATION OF TERRESTRIAL VERTEBRATES
TLDR
Adult anatomy and patterns of development in frogs and salamanders support their origin from different families of dissorophoid labyrinthodonts, and the ancestry of amniotes apparently lies among very early anthracosaurs. Expand

A complete primitive rhizodont from Australia
TLDR
The new evidence shows that rhizodonts are more remote from tetrapods than are osteolepiform and elpistostegid lobe-fin fishes and the pectoral fin of Sauripteris should not be used as a model limb precursor. Expand
Elginerpeton pancheni and the earliest tetrapod clade
TLDR
Elginerpeton, described here on the basis of cranial remains from Scat Craig, is, together with the fragmentary genus Obruchevichthys from the Upper Frasnian of Latvia and Russia, the oldest known stem tetrapod. Expand
Rapid braincase evolution between Panderichthys and the earliest tetrapods
TLDR
The complete braincase of the fish Panderichthys rhombolepis is presented, showing that the braincase retained the intracranial joint, conforming wholly to the generalized pattern of lobe-finned fish, and sharing no obvious derived features with tetrapods. Expand
Are lungfishes the sister group of tetrapods
TLDR
Evidence for the orthodox view of rhipidistian-tetrapod relationships is not as strong as generally believed and Tetrapod-fish relationships need to be re-examined by means of a properly conducted cladistic analysis. Expand
CHARACTER DIAGNOSIS, FOSSILS AND THE ORIGIN OF TETRAPODS
TLDR
A recent review by Rosen et al. (1981) claims that Dipnoi (lungfish) are the sister‐group of the Tetrapoda, that Osteolepiformes is a non‐taxon and that Eusthenopteron is more distant from tetrapods than are Dip noi, coelacanths and probably the fossil Porole piformes, are refuted by use of the same cladistic technique.

XII.—The Postcranial Skeleton of Rhipidistian Fishes Excluding Eusthenopteron
TLDR
The postcranial remains of other Rhipidistia are now described as far as they are known, and comparisons are made with Eusthenopteron and other forms where relevant, and possible modes of function are considered. Expand
The postcranial skeleton of the Devonian tetrapod Tulerpeton curtum Lebedev
TLDR
A cladistic analysis indicates that Tulerpeton is a reptiliomorph stem-group amniote and the earliest known crown-group tetrapod: Acanthostega and Ichthyostega are successively more derived plesion stem- group tetrapods and do not consititute a monophyletic ichthyostegalian radiation. Expand
A new rhizodontiform fish from the Early Carboniferous of Victoria, Australia, with remarks on the phylogenetic position of the group
TLDR
The skull roof of Barameda, gen. nov., differs from that of Osteolepiformes in having a larger extratemporal bone that contacts the intertemporal, by the overlap areas on the interTemporal, and in having fewer snout bones. Expand
Earliest known tetrapod braincase and the evolution of the stapes and fenestra ovalis
ACANTHOSTEGA gunnari, from the Upper Devonian (Famennian) of East Greenland, is the most primitive known tetrapod, and retains many fish-like characters1–4. I report here the discovery of furtherExpand
IX.—The Postcranial Skeleton of Ensthenopteron foordi Whiteaves *
TLDR
A functional analysis of the skeleton of Ensthenopteron is attempted, suggesting that it resembled the pike in its mode of life and that it may have been capable of short journeys “walking” overland. Expand
