Amniotes include mammals, reptiles and birds, representing 75% of extant vertebrate species on land. They originated around 318 million years ago in the early Late Carboniferous and their early fossil record is central to understanding the expansion of vertebrates in terrestrial ecosystems. We present a phylogenetic hypothesis that challenges the widely accepted consensus about early amniote evolution, based on parsimony analysis and Bayesian inference of a new morphological dataset. We find a… 
Varanopid from the Carboniferous of Nova Scotia reveals evidence of parental care in amniotes
A fossil synapsid from the Carboniferous period of Nova Scotia that displays evidence of parental care is reported that adds to growing evidence that parental care was more widespread among Palaeozoic synapsids than previously thought and provides data permitting the identification of potential ontogeny-dependent traits within varanopids.
Multiple paths to morphological diversification during the origin of amniotes.
Evidence for an early burst, comprising high rates of anatomical change that decelerated through time, giving way to a background of saturated morphological evolution is found, demonstrating the importance of variation in modes of phenotypic divergence during a major evolutionary radiation.
A new phylogenetic hypothesis of Tanystropheidae (Diapsida, Archosauromorpha) and other “protorosaurs”, and its implications for the early evolution of stem archosaurs
The polyphyly of “Protorosauria” is confirmed and therefore the usage of this term should be abandoned and a new phylogenetic hypothesis is presented that comprises a wide range of archosauromorphs, including the most exhaustive sample of ”protorosaurs” to date and several “protorosaur” taxa from the eastern Tethys margin that have not been included in any previous analysis.

An examination of local species richness (alpha diversity) of synapsids and reptiles during the Pennsylvanian and Cisuralian at different spatial scales shows that these taxonomic revisions have substantial impacts on relative diversity patterns of synapid and reptiles.
Can We Reliably Calibrate Deep Nodes in the Tetrapod Tree? Case Studies in Deep Tetrapod Divergences
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.
An additional specimen of owenettid procolophonoid from the Middle Triassic of Southern Brazil
A morphological disparity analysis reveals no overlapped areas between the morphospace occupied by procolophonids and owenettids, reinforcing the existence of these two distinct groups.
Tracking the Origin and Early Evolution of Reptiles
The origin of Reptilia and the biostratigraphic and palaeobiogeographic distribution of its early representatives are still poorly understood. An independent source of information may come from the
The Making of Calibration Sausage Exemplified by Recalibrating the Transcriptomic Timetree of Jawed Vertebrates
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.
Evolutionary Change in Locomotion Close to the Origin of Amniotes Inferred From Trackway Data in an Ancestral State Reconstruction Approach
It is demonstrated that steps in early amniote locomotion evolution can be addressed by applying methods of ancestral state reconstruction on trackway data – a novel approach in tetrapod ichnology.


The oldest parareptile and the early diversification of reptiles
Stratigraphic calibration of the results indicates that parareptiles began their evolutionary radiation before the close of the Carboniferous Period, and that the diversity of end-Carboniferous reptiles is 80% greater than suggested by previous work.
A new Early Permian reptile and its significance in early diapsid evolution
A phylogenetic analysis identifies O. mayorum as the oldest and most basal member of the araeoscelidian sister group, and a new diapsid neatly spans the above gap by appearing 15 Myr after the origin of Diapsida.
Interrelationships of basal synapsids: cranial and postcranial morphological partitions suggest different topologies
A new phylogenetic dataset comprising 45 taxa (plus four outgroups and four therapsids) and 239 characters reveals considerable uncertainty in the relationships of higher clades of basal synapsids, and suggests well-supported phylogenetic placements for several taxa of historically uncertain affinities.
The importance of the critical fossils seems to reside in their relative primitive‐ness, and the simplest explanation for their more conservative nature is that they have had less time to evolve.
Response: A Reassessment of the Taxonomic Position of Mesosaurs, and a Surprising Phylogeny of Early Amniotes
The early amniote clade Mesosauridae has long been of interest to scientists, primarily due to the members of the clade being the oldest secondarily aquatic tetrapods and their role as a line of
Evolutionary origin of the turtle skull
High-resolution computed tomography and a novel character/taxon matrix are used to study the skull of Eunotosaurus africanus, a 260-million-year-old fossil reptile from the Karoo Basin of South Africa, whose distinctive postcranial skeleton shares many unique features with the shelled body plan of turtles.
The first record of a nyctiphruretid parareptile from the Early Permian of North America, with a discussion of parareptilian temporal fenestration
The Richards Spur Locality of Oklahoma, USA, long known for its highly diverse Early Permian terrestrial tetrapod assemblage, is particularly interesting for the presence of many endemic taxa. The
A reevaluation of early amniote phylogeny
It is indicated that three major clades of amniotes extend from the present to the Palaeozoic, and these three clades are the Synapsida (including Mammalia), Parareptilia (including Testudines), and Eureptili (including Sauria).
Toward consilience in reptile phylogeny: miRNAs support an archosaur, not lepidosaur, affinity for turtles
This work recovers strong support for turtles sharing a more recent common ancestor with archosaurs, and tests the hypothesis with an expanded miRNA presence/absence dataset, and employs more rigorous criteria for miRNA annotation.
Molecular phylogeny and divergence times of deuterostome animals.
It is found that most major lineages of deuterostomes arose prior to the Cambrian Explosion of fossils and that several lineages had originated before periods of global glaciation in the Precambrian.
