ABSTRACT The late Viséan anthracosauroid Eldeceeon rolfei from the East Kirkton Limestone of Scotland is re-described. Information from two originally described and two newly identified specimens broadens our knowledge of this tetrapod. A detailed account of individual skull bones and a revision of key axial and appendicular features are provided, alongside the first complete reconstructions of the skull and lower jaw and a revised reconstruction of the postcranial skeleton. In comparison to… 
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.
A new large embolomere from East Kirkton
The well-known late Mississippian/early Carboniferous locality of East Kirkton in Scotland has the earliest described fauna of terrestrial tetrapods. Seven species are now known, represented by
The Making of Calibration Sausage Exemplified by Recalibrating the Transcriptomic Timetree of Jawed Vertebrates
TLDR
The present work reevaluate all thirty calibrations in detail, present the current state of knowledge on them with its various uncertainties, rerun the dating analysis, and conclude that calibration dates cannot be taken from published compendia or other secondary or tertiary sources without risking strong distortions to the results.

TLDR
A new cladistic analysis, built from combining characters used in two recent matrices, places Silvanerpeton in a basal position relative to embolomeres and more derived stem amniotes, and informs character polarity near the base of the amniote total group.
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.
Skull and postcranium of the bystrowianid Bystrowiella schumanni from the Middle Triassic of Germany, and the position of chroniosuchians within Tetrapoda
TLDR
Phylogenetic analysis, particularly based on numerous new postcranial features, supports the monophyly of chroniosuchians, even when the constituent synapomorphies (osteoderm and vertebral characters) are excluded from the matrix.
Cranial Anatomy, Ontogeny, and Relationships of the Late Carboniferous Tetrapod Gephyrostegus bohemicus Jaekel, 1902
TLDR
Cranial morphology of the Late Carboniferous terrestrial tetrapod Gephyrostegus bohemicus from the coal deposits of the Nýřany Basin in the Czech Republic is reviewed and a phylogenetic analysis retrieves Gep hyrostegidae as sister group to Seymouriamorpha, although this wider clade receives low bootstrap support.
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.
Westlothiana lizziae from the Viséan of East Kirkton, West Lothian, Scotland, and the amniote stem
Westlothiana lizziae is known from the Brigantian of East Kirkton, Scotland. The skull resembles that of later amniotes in the large size of the parietal, the apparent loss of the intertemporal, and

TLDR
A comparative analysis of this new material and other tetrapodomorph humeri revealed how an increase in humeral torsion transformed the course of the brachial artery and median nerve through the bone, from an entirely ventral path to one in which the blood vessel and nerve passed through the entepicondyle from the dorsal to the ventral surface.
The seymouriamorph tetrapod Ariekanerpeton sigalovi from the Lower Permian of Tadzhikistan. Part I: Cranial anatomy and ontogeny
  • J. Klembara, M. Ruta
  • Biology
    Transactions of the Royal Society of Edinburgh: Earth Sciences
  • 2005
TLDR
The cranial anatomy of Ariekanerpeton sigalovi (Seymouriamorpha: Discosauriscidae; Lower Permian, Tadzhikistan) is described, highlighting new diagnostic features which permit a new skull reconstruction and revised diagnosis.
A redescription of Orovenator mayorum (Sauropsida, Diapsida) using high‐resolution μCT, and the consequences for early amniote phylogeny
TLDR
The earliest known neodiapsid Orovenator mayorum from the lower Permian of Oklahoma is redescribed using high‐resolution μCT, revealing remarkable details of the skull anatomy and prompting questions about relationships among early amniotes.
The stapes of the Coal Measures embolomere Pholiderpeton scutigerum Huxley (Amphibia: Anthracosauria) and otic evolution in early tetrapods
TLDR
The embolomere middle ear structure is reinterpreted as a receiver for low-frequency sound and the ‘otic notch’ is not considered to have housed a tympanum, a conclusion which forces the abandonment of the concept of a ‘labyrinthodont middle ear’.
