  author={Michel Laurin and Oc{\'e}ane Lapauze and David Marjanovi{\'c}},
The origin of extant amphibians has been studied using several sources of data and methods, including phylogenetic analyses of morphological data, molecular dating, stratigraphic data, and integration of ossification sequence data, but a consensus about their affinities with Paleozoic tetrapods has failed to emerge. We have compiled five datasets to assess the relative support for six competing hypotheses about the origin of extant amphibians: a monophyletic origin among temnospondyls, a… 

A Review of the Fossil record of Gymnophiona (Tetrapoda; Lissamphibia) with Comments on Its Use to Calibrate Molecular Timetrees

Gymnophiona, the most poorly known group of extant amphibians, includes elongated limbless tetrapods, with compact ossified skulls and reduced eyes, mainly adapted to fossorial life (only the

A review of the fossil record of caecilians (Lissamphibia: Gymnophionomorpha) with comments on its use to calibrate molecular timetrees

The caecilian fossil record is revisited, providing a brief description of all known extinct taxa described so far, along with general remarks about their impact on systematics, time range, and geographical distribution of the clade, as well as prospects for future research.

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.

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.

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.

Morphology of the temporal skull region in tetrapods: research history, functional explanations, and a new comprehensive classification scheme

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.

Skull development in the Iberian newt, Pleurodeles waltl (Salamandridae: Caudata: Amphibia): timing, sequence, variations, and thyroid hormone mediation of bone appearance

The findings indicate that TH involvement in the mediation of cranial development changes from minimal (if at all) in its early stages to maximal during metamorphosis.

Palatal morphology predicts the paleobiology of early salamanders

It is statistically demonstrated using geometric morphometric analysis that both the shape of the palate and many non-shape variables particularly associated with vomerine teeth are ecologically informative in early stem- and basal crown-group salamanders.

A chromosome-level genome assembly of Cairina moschata and comparative genomic analyses

The chromosome-level genome assembly of Muscovy duck and comparative genomic analyses provide valuable resources for future molecular ecology studies, as well as the evolutionary arms race between the host and influenza viruses.

The scratch-digging lifestyle of the Permian “microsaur” Batropetes as a model for the exaptative origin of jumping locomotion in frogs

Batropetes may represent an analog or possibly a homolog of the digging stage that preceded the origin of Salientia, and the possibility of homology with the digging lifestyles of other “microsaurs” and other amphibians is discussed.



Evolution of ossification sequences in salamanders and urodele origins assessed through event‐pairing and new methods

Analyzing ossification sequences of 24 cranial bones of 23 extant species of salamanders using the event‐pairing method reveals new developmental synapomorphies for several extant salamander taxa and ancestral sequences for Urodela under four alternative reference phylogenies.

Mitogenomic perspectives on the origin and phylogeny of living amphibians.

It is suggested that the temnospondyl-origin hypothesis for lissamphibians is more credible than other hypotheses, and under this timescale, the potential geographic origins of the main living amphibian groups are discussed.

Ontogenetic evidence for the Paleozoic ancestry of salamanders

Comparison of patterns of larval development in Paleozoic and modern amphibians provides a means to test previous phylogenies based primarily on adult characteristics and proves to be highly informative in the case of the origin of salamanders.

The origin of modern amphibians: a re-evaluation

A matrix based on data from all three hypotheses and analysed key taxa phylogenetically using both Bayesian inference and parsimony supported the temnospondyl hypothesis of lissamphibian origins.

A stem batrachian from the Early Permian of Texas and the origin of frogs and salamanders

The discovery of an amphibamid temnospondyl from the Early Permian of Texas that bridges the gap between other Palaeozoic amphibians and the earliest known salientians and caudatans from the Mesozoic is reported.

Ontogenetic sequence reconstruction and sequence polymorphism in extinct taxa: an example using early tetrapods (Tetrapoda: Lepospondyli)

Five different methods of ontogenetic sequence reconstruction are compared and their effects on the detection of sequence polymorphism are compared, using a large collection of the extinct vertebrates Microbrachis pelikani and Hyloplesion longicostatum to suggest an underlying conservative ancestral pattern that evolved early in tetrapod history.

Conserved relative timing of cranial ossification patterns in early mammalian evolution

Ossification of early, middle, and late events are similarly labile, with basicranial traits the most labile in timing of onset of ossification.

Dates, nodes and character conflict: Addressing the Lissamphibian origin problem

Tests of different crown topologies show that placement of amphibians within lepospondyls is not a significantly worse fit for the whole character set than a close temnospondyl‐lissamphibian relationship, and the latter phylogenetic hypothesis best captures the most coherent assembly of derived lissampshibian apomorphies.

Skeletal Morphogenesis of Microbrachis and Hyloplesion (Tetrapoda: Lepospondyli), and Implications for the Developmental Patterns of Extinct, Early Tetrapods

The phylogenetic position and developmental patterns of M. pelikani and H. longicostatum are congruent with the hypothesis that early tetrapods lacked metamorphosis ancestrally and that stem-amniotes exhibited derived features of development, such as rapid and complete ossification of the skeleton, potentially prior to the evolution of the amniotic egg.

Stem caecilian from the Triassic of Colorado sheds light on the origins of Lissamphibia

The hypothesis of caecilian origins closes a substantial morphologic and temporal gap and explains the appeal of morphology-based polyphyly hypotheses for the origins of Lissamphibia while reconciling molecular support for the group’s monophyly.
