We present an update of our time-calibrated supertree of extant and extinct lissamphibians (Marjanović D, Laurin M. 2007. Fossils, molecules, divergence times, and the origin of lissamphibians. Syst Biol 56(3):369–388) and of the divergence dates that can be inferred from it. The present version contains 319 extinct species or possible species of lissamphibians, compared to 223 previously. Discoveries of new fossiliferous sites, advances in phylogeny and recently obtained radiometric dates have… 

Revision of the skeletal morphology of Eodiscoglossus santonjae, an Early Cretaceous frog from northeastern Spain, with comments on its phylogenetic placement

The holotype of the “archaeobatrachian” frog Eodiscoglossus santonjae Villalta, 1954 is redescribed herein, with focus on some features that have been misinterpreted, with the conclusion that more than one taxon might be represented in this sample.

The Lissamphibian Fossil Record of South America

Anurans, along with urodeles and caecilians are the extant representatives of the clade Lissamphibia. Nowadays, lissamphibians are widely distributed in all continents, except Antarctica, but are

Histological study of karaurids, the oldest known (stem) urodeles

Bone histology reveals that the growth of Marmorerpeton and the related unnamed caudate was fairly slow and cyclic, a characteristic of extant lissamphibians, and strengthens the case for the presence of neoteny in these taxa.

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.

The fossil record is dominated by frogs, but there also are notable occurrences of other lissamphibians, including several genera of enigmatic Cretaceous salamanders, one of two known stem caecilians, and the only Gondwanan records for albanerpetontids.

An Extremely Peramorphic Newt (Urodela: Salamandridae: Pleurodelini) from the Latest Oligocene of Germany, and a New Phylogenetic Analysis of Extant and Extinct Salamandrids

An Oligocene newt specimen from western Germany that has gone practically unnoticed in the literature despite having been housed in the Museum für Naturkunde (Berlin) for a century is described and neontologists working on salamandrids are urged to pay renewed attention to the skeleton, not limited to the skull, as a source of diagnostic and phylogenetically informative characters.

The last Palaeoproteus (Urodela: Batrachosauroididae) of Europe

A new species is described, Palaeoproteus miocenicus, from the early late Miocene of Austria and Ukraine, representing the youngest record of the family Batrachosauroididae from the Neogene of Europe and expands the temporal range of the genus by at least 30 million years and enlarges the palaeogeographic distribution of the species into Eastern Europe.

Phylogeny of Paleozoic limbed vertebrates reassessed through revision and expansion of the largest published relevant data matrix

Even in its revised state, the matrix cannot provide a robust assessment of the phylogeny of early limbed vertebrates, and approaches to coding, methods of phylogenetics, and prospects for further improvement are discussed.

Evolutionary History of the Asian Horned Frogs (Megophryinae): Integrative Approaches to Timetree Dating in the Absence of a Fossil Record

Molecular phylogenetic, morphological, and timetree results support the recognition of Megophryinae as a single genus, Megophrys, with a subgenus level classification.



Fossils, molecules, divergence times, and the origin of lissamphibians.

A review of the paleontological literature shows that the early dates of appearance of Lissamphibia recently inferred from molecular data do not favor an origin of extant amphibians from

Fossils, molecules, divergence times, and the origin of Salamandroidea

A study in PNAS shows that rapprochement within at least salamander phylogeny may be within grasp, with molecular estimates being much older than the fossil record suggests.

A reevaluation of the evidence supporting an unorthodox hypothesis on the origin of extant amphibians

The most parsimonious trees - now longer by almost 64% - support one of the three commonly advocated hypotheses, namely a monophyletic Lissamphibia nested, together with its sister-group Albanerpetontidae, within the temnospondyls (next to Doleserpeton) - even though the authors did not add any characters or taxa to the very small data matrix.

Focal Review: The Origin(s) of Modern Amphibians

The present paper reviews the impact of this fossil on morphological and molecular phylogenies, and divergence timing estimates based on molecular models and the fossil record, and raises questions over either the validity of morphological analyses that support lissamphibian polyphyly or about the possibility of long branch attraction given the short internal divergences and long subsequent branches.

A Late Jurassic salamander (Amphibia: Caudata) from the Morrison Formation of North America

The first articulated salamander skeleton from the Jurassic of Euramerica is described, recovered from Upper Jurassic deposits of the Morrison Formation, Dinosaur National Monument, USA, showing a combination of primitive and derived character states that distinguish it from all known Mesozoic salamanders and which permit the erection of a new genus and species.

Late Jurassic salamandroid from western Liaoning, China

A Jurassic salamander, Beiyanerpeton jianpingensis (gen. et sp. nov.), from a recently found site in western Liaoning Province, China is the earliest known record of Salamandroidea, and provides direct evidence supporting the hypothesis that the split between Cryptobranchoidea and Salamandroidesa had taken placed before the Late Jurassic Oxfordian time.

Phylogenetic relationships of the Cretaceous frog Beelzebufo from Madagascar and the placement of fossil constraints based on temporal and phylogenetic evidence

A metric is derived, Δt, to quantify temporal divergence among chronograms and finds that errors resulting from mis‐specified calibrations are localized when additional nodes throughout the tree are properly calibrated.

Assessing Confidence Intervals for Stratigraphic Ranges of Higher Taxa: The Case of Lissamphibia

The results suggest a more recent origin of Lissamphibia than advocated in most recent molecular studies, and are more compatible with monophyly than with polyphyly of the extant amphibians, but heavily depend on poorly constrained assumptions about lissamp Hibian extinction rates during biological crises.

A New Helmeted Frog (Anura: Calyptocephalellidae) from an Eocene Subtropical Lake in Northwestern Patagonia, Argentina

Eocene caldera-lake deposits from Río Pichileufú have yielded anuran remains in association with a taxonomically diverse flora that represent a new species that can be assigned to the extant genus Calyptocephalella on the basis of both cranial and postcranial traits.

Progress has been made in compiling databases and supertrees incorporating paleontological data, in computing confidence intervals on the true stratigraphic range of taxa, and in using birth-and-death processes to assess the probability distribution of the time of origin of specified taxa.
