The transition from fishes to tetrapods was one of the most dramatic events in the evolution of vertebrates, but many pivotal fossils are incomplete, resulting in gaps in the data that are used for phylogenetic reconstruction. Here we present new observations from the most complete, acid-prepared Devonian tetrapodomorph fish yet discovered, Gogonasus, which was previously placed just crownward of Kenichthys and rhizodontids, the most primitive taxa on the tetrapod lineage. Unexpectedly… 

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. Devonian

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.

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.

Owensia chooi: a new tetrapodomorph fish from the Middle Devonian of the South Blue Range, Victoria, Australia

A new cosmine-covered, tetrapodomorph fish Owensia chooi gen. et sp. nov. is described, based on a near-complete, uncrushed ethmosphenoid from the Middle Devonian sediments (Kevington Creek

Ever Since Owen: Changing Perspectives on the Early Evolution of Tetrapods

TLDR
Research emphasis can now shift to broader-based questions, including the whole of the early tetrapod radiation, from the divergence from other lobed-finned fishes to the origins of modern amphibians and amniotes.

On the phylogenetic position of Gogonasus andrewsae Long 1985, within the Tetrapodomorpha

TLDR
New phylogenetic analyses of the Tetrapodomorpha show a revised phylogenetic position of Gogonasus as being deeply nested within the Tetrapsidium, crownward of Osteolepis and Megalichthys, but basal to Eusthenopteron+‘elpistostegalids’.

A new actinopterygian from the Late Devonian Gogo Formation, Western Australia

The study of early actinopterygians (ray‐finned fishes) from the Devonian has been hampered by imperfect preservation in the majority of taxa. The Late Devonian (early Frasnian) Gogo Formation of

Rise of the Earliest Tetrapods: An Early Devonian Origin from Marine Environment

TLDR
The results have shown that tetrapods evolved from marine environments during times of higher oxygen levels, and the change in environmental conditions played a major role in their evolution.

Sarcopterygians: From Lobe-Finned Fishes to the Tetrapod Stem Group

TLDR
The sarcopterygians or lobe-finned fishes is the group that gave rise to tetrapod-like forms from the Late Devonian, and the braincases of dipnoans (lungfishes) were the most highly modified with consolidated fore and aft portions and reduction or loss of the hyomandibula.

A near‐tetrapod from the Baltic Middle Devonian

TLDR
Livoniana has a strikingly autapomorphic dentary dentition comprising multiple tooth rows, providing evidence both for the unexpectedly early evolution of tetrapod characteristics and for morphological radiation around the fish‐tetrapod transition.

Osteolepiforms and the ancestry of tetrapods

TLDR
The supposedly discredited idea of osteolepiforms as tetrapod ancestors is supported by the first detailed analysis of the lower part of the Tetrapodomorpha, based on 99 characters scored for 29 taxa.

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.

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.

The First Tetrapod Finds from the Devonian (Upper Famennian) of Latvia

TLDR
The lower jaw of Ventastega is strikingly primitive in retaining fangs on the coronoid series, but shares many characters with those of other known Devonian tetrapods, and some of these features are interpreted as basal tetrapod synapomorphies.

Tetrapod-like middle ear architecture in a Devonian fish

TLDR
It is shown that the spiracular region is radically transformed from osteolepiforms and represents the earliest stages in the origin of the tetrapod middle ear architecture, suggesting that the middle ear of early tetrapods evolved initially as part of a spiracular breathing apparatus.

TLDR
It is argued that the Rhizodontida evolved on the Gondwanan landmass, and notorhizodon occupies a relatively derived position within the Tristichopteridae, but is contemporary with the earliest and phylogenetically most basal Laurussian members of the group.

TLDR
The discovery of the first Devonian tetrapod from Asia is reported, a finding that substantially extends the geographical range of these animals and raises new questions about their dispersal.

A NEW SPECIES OF BARAMEDA (RHIZODONTIDA) AND HETEROCHRONY IN THE RHIZODONTID PECTORAL FIN

TLDR
Observations of the Australian Lower Carboniferous rhizodontid Barameda suggest a degree of developmental variability (timing, degree of ossification) in the entepicondyle relative to the rest of the humerus, which could be extended to other posterior processes of pectoral fin elements such as the ulnare flange.
