The origin of terrestrial vertebrates represents one of the major evolutionary and ecological transformations in the history of life, and the established timing and environment of this transition has recently come under scrutiny. The discovery and description of a well-preserved fossil sarcopterygian (fleshy-limbed vertebrate) from the Middle Devonian of Nevada helps to refine and question aspects of the temporal and anatomical framework that underpins the tetrapod condition. This new taxon… 
New insights into the origins and radiation of the mid-Palaeozoic Gondwanan stem tetrapods
ABSTRACT The earliest tetrapodomorph fishes appear in Chinese deposits of Early Devonian age, and by the Middle Devonian they were widespread globally. Evidence for the earliest digitated tetrapods
A new elpistostegalian from the Late Devonian of the Canadian Arctic.
TLDR
A new elpistostegalian from the Late Devonian period of the Canadian Arctic that shows surprising disparity in the group, and shows specializations for swimming that are unlike those known from other sarcopterygians.
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
Late to the table: diversification of tetrapod mandibular biomechanics lagged behind the evolution of terrestriality.
TLDR
The substantial temporal gap between the origin of postcranial features associated with terrestriality, such as limbs with functional elbow/knee and wrist/ankle joints capable of weight-bearing, and the onset of divergence in jaw biomechanics provides a compelling example of "functional modularity" during a major adaptive radiation.
A New Species of Eusthenodon (Sarcopterygii, Tristichopteridae) from the Upper Devonian (Famennian) of Pennsylvania, U.S.A., and a Review of Eusthenodon Taxonomy
TLDR
A new species of Eusthenodon from the Upper Devonian (Famennian) Catskill Formation was collected from talus blocks at the base of a road cut along the Cogan House Exit Ramp on U.S. 15/Interstate 99 and may support the hypothesis that tristichopterids occupied the role of top predator in the freshwater ecosystems of the Catskill Delta complex.
Elpistostege and the origin of the vertebrate hand
TLDR
It is suggested that the vertebrate hand arose primarily from a skeletal pattern buried within the fairly typical aquatic pectoral fin of elpistostegalians, and is potentially the sister taxon of all other tetrapods, and its appendages further blur the line between fish and land vertebrates.
A Gigantic Sarcopterygian (Tetrapodomorph Lobe-Finned Fish) from the Upper Devonian of Gondwana (Eden, New South Wales, Australia)
TLDR
The hypothesis that tristichopterids evolved in Laurussia and later dispersed into Gondwana, and a derived subgroup of large Late Devonian genera dispersed from Gondswana, is inconsistent with the evidence of the new taxon.
The first “osteolepiform” tetrapodomorph (Sarcopterygii) from the Paleozoic sequences of the Moravian Karst (Czech Republic)
The first tetrapodomorph specimen from the Palaeozoic sequences of the Moravian Karst (Moravo-Silesian Basin, Bohemian Massif, Czech Republic) is described. The well preserved, cosmine-covered
A review of recent discoveries of exceptionally preserved fossil fishes from the Gogo sites (Late Devonian, Western Australia)

TLDR
Through their exceptional preservation of both hard and varied kinds of soft tissues, the Gogo fishes remain crucial for resolving key debates on the diversification, physiology, biomechanics and phylogenetic relationships of early gnathostomes.
A tristichopterid sarcopterygian fish from the upper Middle Devonian of Nevada
TLDR
A new tristichopterid is described from the uppermost Givetian, Middle Devonian, from the Northern Simpson Park Range in central Nevada, USA and has enlarged premaxillary ‘pseudofangs’ and anterior dentary fangs, features of ‘moderately derived’ tristicopterids.

The Late Devonian Gogo Formation Lägerstatte of Western Australia: Exceptional Early Vertebrate Preservation and Diversity
TLDR
The Gogo Formation of Western Australia preserves a unique Late Devonian reef fauna that has produced data on the oldest known vertebrate embryos, the anatomy of the primitive actinopterygian neurocranium, and the histology, radiation, and plasticity of dipnoan (lungfish) dental and cranial structures.
The Early Evolution of the Tetrapod Humerus
TLDR
A comparative analysis of this fossil and other relevant humeri from the Devonian shows that the role of the limb in propping the body arose first in fish fins, not tetrapod limbs.
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.
The axial skeleton of the Devonian tetrapod Ichthyostega
TLDR
A new reconstruction of Ichthyostega is shown based on extensive re-examination of original material and augmented by recently collected specimens and reveals hitherto unrecognized regionalization in the vertebral column.
Tetrapod trackways from the early Middle Devonian period of Poland
TLDR
Well-preserved and securely dated tetrapod tracks from Polish marine tidal flat sediments of early Middle Devonian (Eifelian stage) age are presented, forcing a radical reassessment of the timing, ecology and environmental setting of the fish–tetrapod transition, as well as the completeness of the body fossil record.
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.
A primitive amphibian from the Late Devonian of New South Wales
TLDR
The musculatures of rhipidistian and amphibian jaws are analysed and are shown to be functionally related to distinctive morphologies of the articulatory region in each group, Metaxygnathus being of amphibian type.
The Fin to Limb Transition: New Data, Interpretations, and Hypotheses from Paleontology and Developmental Biology
TLDR
New ideas generated from recent fossil finds and from developmental biology that bear on the question of how limbs, digits, limb joints, and pentadactyly evolved are considered.
A fishy mosasaur: the axial skeleton of Plotosaurus (Reptilia, Squamata) reassessed
TLDR
Analysis of vertebral centrum morphometrics and process orientation has revealed that a subsequent clade of secondarily aquatic reptiles, the mosasaurs, had developed a deep, fusiform body and a probable pursuit-predatory behaviour by the time of their sudden extinction at the Cretaceous-Paleogene boundary.
