Synopsis Extant amphibians consist of Salientia (frogs), Caudata (salamanders), and Gymnophiona (caecilians). The mutual relationships of these groups are controversial, with either Batrachia (Salientia + Caudata) or Procera (Gymnophiona + Caudata) as emerging clades in recent molecular and morphological analyses. The monophyly of amphibians as a whole is supported by independent data, but their origins and affinities with early tetrapods are debated. A new cladistic analysis of early tetrapods… 

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.

The putative lissamphibian stem-group: phylogeny and evolution of the dissorophoid temnospondyls

An inclusive phylogenetic analysis of dissorophoids gives new insights into the large-scale topology of relationships, including a basal dichotomy between the large, heavily ossified Olsoniformes and the small salamander-like Amphibamiformes.

The evolution of major temnospondyl clades: an inclusive phylogenetic analysis

Phylogenetic analysis of a large dataset focuses on the in-group relationships of temnospondyls, the largest lower tetrapod clade, and found the following groups were unequivocally found to be monophyletic: Edopoidea (node), Dvinosauria (stem, excl. Brachyopidae), DissorophoideA ( node), Eryopidae (stem), and Stereosponyli (node).

The intrarelationships and evolutionary history of the temnospondyl family branchiosauridae

An evolutionary scenario suggests that branchiosaurids originated by invention of a key innovation: specialized pharyngeal denticles, housed in gill clefts, served as a filter‐feeding device focussing on plankton.

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.

Phylogeny of the amphibamiform temnospondyls: the relationship of taxa known by adults, larvae and neotenes

The present analysis finds the hypothesized olsoniform larvae from Nýřany to be adults of Branchiosaurus salamandroides, whereas some of the larvae from Mazon Creek are not branchiosaurids, but immature specimens of the amphibamid Amphibamus grandiceps.

Temnospondyl ontogeny and phylogeny, a window into terrestrial ecosystems during the Permian-Triassic mass extinction

This study represents the largest and most comprehensive species-level phylogenetic study of Temnospondyli, sampling 99 taxa for 297 morphological characters from all seven continents through nearly 170 million years of their evolutionary history to support the monophyly of several clades.

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.

A revision of Scincosaurus (Tetrapoda, Nectridea) from the Moscovian of Nyrany, Czech Republic, and the phylogeny and interrelationships of nectrideans

The morphology of the terrestrial nectridean Scincosaurus, from the Moscovian ‘Gaskohle’ near Nýřany, Czech Republic, is revised in detail. Its anatomical characters are incorporated in a new



Monophyly and affinities of albanerpetontid amphibians (Temnospondyli; Lissamphibia)

Albanerpetontids are better interpreted not as aberrant caudates, but as a distinct clade of lissamphibians in which numerous apomorphies are superimposed upon an otherwise primitive lissampshibian body plan.


The balance of evidence favors a monophyletic origin of all lissamphibians from within the tem- nospondyls but the number of character states involved is not so great that this theory can be considered robust.

Strong support of the Batrachia hypothesis from both molecule- and morphology-based studies provides a robust phylogenetic framework that will be helpful to comparative studies among the three living orders of amphibians and will permit better understanding of the considerably divergent vertebral, brain, and digit developmental patterns found in frogs and salamanders.

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.

Molecular evidence for the early history of living amphibians.

Evidence from the DNA sequences of four mitochondrial genes that challenges the conventional hypothesis and supports a salamander-caecilian relationship is presented and suggests a more recent (Mesozoic) origin for salamanders and caecilians directly linked to the initial breakup of the supercontinent Pangaea.

Initial Diversification of Living Amphibians Predated the Breakup of Pangaea

A robust molecular phylogeny based on the nuclear RAG1 gene as well as results from a variety of alternative independent molecular clock calibrations suggest that the origin and early divergence of the three living amphibian orders dates back to the Palaeozoic or early Mesozoic, before the breakup of Pangaea, and soon after the divergence from lobe‐finned fishes.

A three-stage dentitional ontogenetic sequence for Doleserpeton and Tersomius is proposed, in which the third (adult) phase is similar to the adult of most other labyrinthodonts, the second (juvenile) phase resembles the adult condition in lissamphibians whereas the hypothetical first (larval)phase resembles the larvae of salamanders and oviparous caecilians.

Archaeobatrachian paraphyly and pangaean diversification of crown-group frogs.

To explore central controversies on the phylogeny of Anura, nearly 4000 base pairs of mitochondrial and nuclear DNA for the major frog lineages are analyzed and likelihood-based analyses are congruent with morphological evidence in supporting a paraphyletic arrangement of archaeobatrachian frogs.

A stem‐group caecilian (Lissamphibia: Gymnophiona) from the Lower Cretaceous of North Africa

This material represents the second oldest record for the caecilians, after the Jurassic Eocaecilia of North America, and the earliest caecilian record for Gondwana, and forms the basis of a new genus, Rubricacaecilia.
