The origin of amniotes was a key event in vertebrate evolution, enabling tetrapods to break their ties with water and invade terrestrial environments. Two pivotal clades of early tetrapods, the diadectomorphs and the seymouriamorphs, have played an unsurpassed role in debates about the ancestry of amniotes for over a century, but their skeletal morphology has provided conflicting evidence for their affinities. Using high-resolution X-ray microcomputed tomography, we reveal the three-dimensional… Expand
Braincase and Inner Ear Anatomy of the Late Carboniferous Tetrapod Limnoscelis dynatis (Diadectomorpha) Revealed by High-Resolution X-ray Microcomputed Tomography
The braincase anatomy of the Pennsylvanian diadectomorph Limnoscelis dynatis is described in detail, based upon high-resolution X-ray microcomputed tomography. Both supraoccipitals and most of theExpand
Neurocranial Anatomy of Seymouria from Richards Spur, Oklahoma
ABSTRACT Seymouriamorphs are a group of Permo-Carboniferous tetrapods with both terrestrial and aquatic members. Since their initial discovery, they have been proposed as phylogenetic intermediatesExpand
Heading for higher ground: Developmental origins and evolutionary diversification of the amniote face.
TLDR
A model for facial evolution in the amniotes is proposed, based on the differential rate of cranial neural crest cell proliferation and the timing of their skeletal differentiation, to explain the outstanding scale of adaptive facial diversity. Expand
Anatomy of the neural endocranium, parasphenoid and stapes of Diadectes absitus (Diadectomorpha) from the early Permian of Germany based on the high‐resolution X‐ray microcomputed tomography
A detailed anatomy of the braincase and stapes of the subadult specimen of Diadectes absitus from early Permian sediments of Germany are described for the first time based on the high‐resolutionExpand
Morphology of the temporal skull region in tetrapods: research history, functional explanations, and a new comprehensive classification scheme
TLDR
A novel comprehensive classification scheme for the various temporal morphotypes in all Tetrapoda that is independent of phylogeny and previous terminology is introduced that may facilitate morphological comparisons in future studies. Expand
Limb-Bone Development of Seymouriamorphs: Implications for the Evolution of Growth Strategy in Stem Amniotes
Tetrapod life on land was the result of a lengthy process, the final steps of which resulted in full independence of amniotic tetrapods from the aquatic environment. Developmental strategies,Expand
A review of the stem amniote Eldeceeon rolfei from the Viséan of East Kirkton, Scotland
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 specimensExpand
Can We Reliably Calibrate Deep Nodes in the Tetrapod Tree? Case Studies in Deep Tetrapod Divergences
TLDR
It is found that node priors for amphibians and tetrapods show high phylogenetic lability and different phylogenetic treatments identifying disparate taxa as the earliest representatives of these crown groups, and it is suggested that sampling outside of classic European and North American sections may dramatically change the timelines of tetrapod evolution.

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.

ORIGIN AND EARLY EVOLUTION OF THE AMNIOTE OCCIPUT
TLDR
A phylogenetic study of major groups of Paleozoic tetrapods based on the occiput and closely associated elements of the skull roof finds that the Anthracosauria and Baphetidae are progressively more distant clades or sister taxa. Expand
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. Expand
Bringing Dicynodonts Back to Life: Paleobiology and Anatomy of a New Emydopoid Genus from the Upper Permian of Mozambique
TLDR
A new dicynodont (Therapsida, Anomodontia) from northern Mozambique is described and synchrotron radiation based micro-computed tomography (SRµCT) combined with a phylogenetic analysis demonstrates a set of characters shared with Emydopoidea. Expand
The Braincase of Eocaecilia micropodia (Lissamphibia, Gymnophiona) and the Origin of Caecilians
TLDR
The braincase of E. micropodia was examined via micro-computed tomography and Ancestral character state reconstruction confirms the braincase to be largely representative of the plesiomorphic condition of extant caecilians. Expand
The last diadectomorph sheds light on Late Palaeozoic tetrapod biogeography
TLDR
The discovery of Alveusdectes raises important questions regarding diadectomorph extinction dynamics including what, if any, ecological factors limited the diversity of this group in eastern Pangea and suggests that increased sampling in Asia will likely significantly affect views of clade and faunal insularity leading up to the Permo-Triassic extinction.

Comparison of the sensitivity of the canals in each of the three major axes of rotation suggests Plioplatecarpus peckensis may have been most sensitive to movements in the pitch axis, and a detailed, three dimensional reconstruction of the osseous labyrinth for the first time. Expand
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.

The braincase and middle ear region of Dendrerpeton acadianum (Tetrapoda: Temnospondyli)
TLDR
The morphology and orientation of the stapes provide strong evidence for the presence of an ear adapted to the perception of airborne sound, with similarities to the extant anuran condition, and the reconstructed braincase shows a high degree of similarity to that of other adequately known temnospondyls.

TLDR
Comparison of the cranial structures of Discosauriscus with those of Seymouria baylorensis, Seymourouria sanjuanensis, and Seymourias shows that Discosuriscus is not a reptile (an amniote animal), and Ariekanerpeton, Utegenia, Urumquia, kotlassiids, leptorophids and Enosuchus require revision.
