Ancient amphibians preserved in amber Extant amphibians are represented by three fairly simple morphologies: the mostly hopping frogs and toads, the low-crawling salamanders, and the limbless caecilians. Until the early Pleistocene—and for more than 165 million years—there was another group, the albanerpetontids. We know little about this group because amphibian fossils are poorly preserved, and previous specimens from this group are both rare and mostly badly damaged. Daza et al. describe a… 
A surprising fossil vertebrate

On page 687 of this issue, Daza et al. (1) introduce an unusual fossil of the obscure and apparently extinct albanerpetontids of the Mesozoic, which paleontologists had overlooked.
A new Early Cretaceous lizard in Myanmar amber with exceptionally preserved integument
This fossil offers a rare opportunity to glimpse the external appearance of one group of lizards during the Early Cretaceous, and was consistently recovered as a scincoid lizard (Scinciformata), as sister to Tepexisaurus  + Xantusiidae.
Middle Jurassic fossils document an early stage in salamander evolution.
Salamanders are an important group of living amphibians and model organisms for understanding locomotion, development, regeneration, feeding, and toxicity in tetrapods. However, their origin and
Late Paleogene herpetofaunas from the crossroads between two continents – new amphibian and reptile remains from the Oligocene of southern Balkans and Anatolia
New amphibian and reptile remains from three Oligocene localities of Turkey are described and the role of a potential southern dispersal route of taxa among Asia and Europe, involving the area of southern Balkans and Anatolia, is highlighted also for amphibians and reptiles.
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
An earliest Triassic age for Tasmaniolimulus and comments on synchrotron tomography of Gondwanan horseshoe crabs
In revisiting these taxa, it is determined that, contrary to previous suggestion, T. patersoni arose after the Permian and the origin of over-developed genal spine structures within Austrolimulidae is exclusive to the Triassic.
The disadvantage of derivation: conserved systematic flaws in primary data have repeatedly biased the phylogenetic inference of Temnospondyli (Tetrapoda, Amphibia)
A thorough reassessment of this matrix and several of its high-profile derivates revealed that the phylogeny of temnospondyls is more poorly known than depicted by the literature and that certain hypotheses of lissamphibian origins within Temnosponyli lack phylogenetic support.
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 scratch-digging lifestyle of the Permian “microsaur” Batropetes Carroll & Gaskill, 1971 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 Laurenti, 1768, and the possibility of homology with the digging lifestyles of other “microsaurs” and other amphibians is discussed.


Albanerpetontid amphibians from the Cretaceous of Spain
The recovery of the first complete albanerpetontid specimens (including traces of skin and possible male courtship glands) from the early Cretaceous of Spain are reported here on, suggesting they represent a distinct lissamphibian lineage.
Albanerpetontid amphibians from the upper Cretaceous (Campanian and Maastrichtian) of North america
Although the three species of Albanerpeton appear to have evolved largely in isolation through the Late Cretaceous in the Western Interior, differences in cranial structure and inferred body size imply that each favored a different ecological niche.
Abstract:  The Albanerpetontidae are salamander‐like, Middle Jurassic to Neogene lissamphibians from Laurasia and North Africa. Extensive series of albanerpetontid bones recently identified in
The first record of albanerpetontid amphibians (Amphibia: Albanerpetontidae) from East Asia
High Resolution X-ray Computed Microtomography has revealed previously unrecorded features of albanerpetontid skull morphology in three dimensions, including the presence of a supraoccipital and epipterygoids, neither of which occurs in any known lissamphibian.
New albanerpetontid amphibians from the albian to Coniacian of Utah, Usa—Bridging the gap
ABSTRACT Newly discovered fossils described herein from Utah, USA, help fill a sizeable gap in the Cretaceous record of the Albanerpetontidae and provide information on the evolution of the family
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.
Mid-Cretaceous amber fossils illuminate the past diversity of tropical lizards
The oldest lizard assemblage preserved in amber is reported, providing insight into the poorly preserved but potentially diverse mid-Cretaceous paleotropics and potential keys for resolving conflicts in higher-order squamate relationships.
the amphibian albanerpeton arthridion and the Aptian–Albian biogeography of albanerpetontids
Albanerpeton arthridionis rediagnosed and redescribed based on jaws, frontals, atlantes and humeri from the Lower Cretaceous (uppermost Aptian–middle Albian), Antlers Formation of Oklahoma and Texas,
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.
