Ichthyostega was the first Devonian tetrapod to be subject to a whole-body reconstruction. It remains, together with Acanthostega, one of only two Devonian tetrapods for which near-complete postcranial material is available. It is thus crucially important for our understanding of the earliest stages of tetrapod evolution and terrestrialization. Here we show a new reconstruction of Ichthyostega based on extensive re-examination of original material and augmented by recently collected specimens… 

Urodelans, Ichthyostega and the origin of the tetrapod limb

TLDR
It is suggested that the fin type ancestral to terrestrial limbs was asymmetrical biserial, possessed a short axis, unbranched jointed preaxial radials deviating from the distal mesomeres of the axis in two or more radials.

Contrasting Developmental Trajectories in the Earliest Known Tetrapod Forelimbs

TLDR
It is inferred that Ichthyostega underwent greater locomotory terrestrialization during ontogeny and could be phylogenetically more basal than Acanthostega, which is generally considered the more primitive tetrapod.

A Devonian tetrapod-like fish and the evolution of the tetrapod body plan

TLDR
The discovery of a well-preserved species of fossil sarcopterygian fish from the Late Devonian of Arctic Canada that represents an intermediate between fish with fins and tetrapods with limbs, and provides unique insights into how and in what order important tetrapod characters arose is reported.

Ventastega curonica and the origin of tetrapod morphology

TLDR
The skull, exceptionally preserved braincase, shoulder girdle and partial pelvis of Ventastega curonica are presented, a transitional intermediate form between the ‘elpistostegids’ Panderichthys and Tiktaalik and the Devonian tetrapods (limbed vertebrates) Acanthostega and Ichthyostega.

A Marine Stem-Tetrapod from the Devonian of Western North America

TLDR
This new taxon, Tinirau clackae, demonstrates that substantial parallelism pervaded the early history of stem-tetrapods, raises additional questions about when digited sarcopterygians first evolved, and further documents that incipient stages of the terrestrial appendicular condition began when sarcoperygians still retained their median fins and occupied aquatic habitats.

The postcranial anatomy of Whatcheeria deltae and its implications for the family Whatcheeriidae

TLDR
The postcranial skeleton is described and the first full-body reconstruction of the early tetrapod Whatcheeria deltae from the Viséan of Iowa is presented, contributing to a revised diagnosis of the family Whatcheeriidae and a re-evaluation of fragmentary Devonian–Carboniferous fossils reported as ‘whatcheeriid’ but sharing no synapomorphies with the more precisely defined clade.

Palaeontology: Between water and land

TLDR
A new reconstruction of Ichthyostega differs radically from previous versions in having a regionalized vertebral column that bears a striking resemblance to that of a mammal, suggesting that the four-legged fish could move on land using a bilaterally symmetrical ‘shuffling’ action.

Morphology of the earliest reconstructable tetrapod Parmastega aelidae

TLDR
Three-dimensionally preserved fossils of Parmastega aelidae, a newly described tetrapod from the earliest Famennian (Late Devonian) of Russia, provide detailed insights into the morphology and palaeobiology of the earliest tetrapods.

Limb‐bone histology of temnospondyls: implications for understanding the diversification of palaeoecologies and patterns of locomotion of Permo‐Triassic tetrapods

TLDR
This study presents the first palaeohistological study based on theoretical biomechanical considerations among a highly diversified group of early tetrapods, the temnospondyls, based on the quantification of microanatomical and histological parameters in the humerus and femur of nine genera.

The smallest known Devonian tetrapod shows unexpectedly derived features

TLDR
Brittagnathus is described from a single complete right lower jaw ramus recovered from the Acanthostega mass-death deposit in the upper part of the Britta Dal Formation of Stensiö Bjerg, Gauss Peninsula, East Greenland and suggests that diversification of ‘Carboniferous-grade’ tetrapods had already begun before the end of the Devonian and that the group was not greatly affected by the end-Devonian mass extinction.

Polydactyly in the earliest known tetrapod limbs

TLDR
The morphology of the specimens suggests that limbs with digits may have been adaptations to an aquatic rather than a terrestrial environment, and challenges pentadactyly as primitive for tetrapods.

Pederpes finneyae, an articulated tetrapod from the tournaisian of Western Scotland

TLDR
The postcranial skeleton of Pederpes shows several unique features, including the structure of the leading edges of the cleithrum and clavicle, the form of the rib flanges and a possible supernumerary digit on the manus.

A uniquely specialized ear in a very early tetrapod

TLDR
Ichthyostega's braincase and ear region defied interpretation, such that conventional anatomical terms seemed inapplicable, and can now be seen to form part of a highly specialized ear, probably a hearing device for use in water.

The Carboniferous Amphibian Proterogyrinus scheelei Romer, and the Early Evolution of Tetrapods

TLDR
Proterogyrinus scheelei Romer, from the Upper Mississippian of Greer, West Virginia, is one of the earliest known members of the amphibian infraorder Embolomeri, and has no undisputed synapomorphies with reptiles either, making it impossible to support close relationship between the two groups.

An early tetrapod from ‘Romer's Gap’

TLDR
Pederpes is the earliest-known tetrapod to show the beginnings of terrestrial locomotion and was at least functionally pentadactyl, bridging the temporal, morphological and phylogenetic gaps that have hitherto separated Late Devonian and mid-Carboniferous tetrapOD faunas.

Early tetrapod relationships revisited

TLDR
A deep split of early tetrapods between lissamphibian‐ and amniote‐related taxa is detected and is indicated by the results of the original parsimony run ‐ as well as those retrieved from several other treatments of the data set.
