Abstract Dissorophoid temnospondyls are widely considered to have given rise to some or all modern amphibians (Lissamphibia), but their ingroup relationships still bear major unresolved questions. An inclusive phylogenetic analysis of dissorophoids gives new insights into the large-scale topology of relationships. Based on a TNT 1.5 analysis (33 taxa, 108 characters), the enigmatic taxon Perryella is found to nest just outside Dissorophoidea (phylogenetic defintion), but shares a range of… 
A redescription of the late Carboniferous trematopid Actiobates peabodyi from Garnett, Kansas
High degree of conservatism indicates that the earliest trematopids were already well adapted for terrestrial environments, and post‐Carboniferous radiations of olsoniforms may be attributed to an expansion of the dryland terrestrial environments in which these taxa already thrived, rather than to novel acquisition of adaptive features later in the clade's evolution.
Size matters: the effects of ontogenetic disparity on the phylogeny of Trematopidae (Amphibia: Temnospondyli)

A specimen-level approach and multiple subsampling permutations are taken to explore the phylogeny of the Trematopidae as a case study for assessing the effects of ontogenetic disparity on phylogenetic reconstruction in temnospondyls and urge caution in the interpretation of phylogenetic analyses for which ontogenetics disparity exists, but is unaccounted for.
Braincase simplification and the origin of lissamphibians
Dissorophoidea, a group of temnospondyl tetrapods that first appear in the Late Carboniferous, is made up of two clades ⎼ Olsoniformes and Amphibamiformes (Branchiosauridae and Amphibamidae) ⎼ the
A new dissorophoid temnospondyl from the Allegheny Group (late Carboniferous) of Five Points, Mahoning County, Ohio (USA)
Abstract. A small temnospondyl skull from the upper Carboniferous Allegheny Group of Five Points, Ohio, is referred to a new dissorophoid, Palodromeus bairdi n. gen n. sp. The complete skull with
A Juvenile Specimen of the Trematopid Acheloma From Richards Spur, Oklahoma and Challenges of Trematopid Ontogeny
The complete skull and articulated mandibles of a diminutive trematopid specimen (OMNH 79318) from the Early Permian karst deposits near Richards Spur, Oklahoma is described, providing evidence that variation in otic notch structure can be ontogenetically influenced, not only among eucacopine dissorophids but also among treMatopids.
The dissorophoid temnospondyl Parioxys ferricolus from the early Permian (Cisuralian) of Texas
Reexamination of the original material and preparation of a previously undescribed specimen shed some light on the ontogeny and reveal numerous eucacopine features in Parioxys ferricolus.
The amphibamiform Nanobamus macrorhinus from the early Permian of Texas
A complete, updated osteological description of N. macrorhinus is presented, including an improved characterization of its unique mosaic of plesiomorphic and apomorphic features and clarification of the taxon's autapomorphies, which reflect the complexity of terrestrial amphibamiform diversity and provide further insight into the evolutionary history of the lissamphibian stem in terrestrial environments.
Returning to the roots: resolution, reproducibility, and robusticity in the phylogenetic inference of Dissorophidae (Amphibia: Temnospondyli)
The phylogeny of the Dissorophidae, a speciose clade of Paleozoic temnospondyls, is addressed, which suggests that previous analyses may have been compromised, and that the only real consensus of dissorophid phylogeny is the lack of one.
Histological skeletochronology indicates developmental plasticity in the early Permian stem lissamphibian Doleserpeton annectens
It is proposed that the weak correlation between age and size represents developmental plasticity in D. annectens that typifies extant lissamphibians and is likely only possible with large sample sizes in extinct taxa, and low sample sizes can produce false, misleading results that warrant caution in drawing paleobiological interpretations from such samples.

ABSTRACT The fossil record of temnospondyl amphibians in the immediate wake of the Permo-Triassic mass extinction captures extensive taxic and ecological diversity, with most records known from high


Character distribution and phylogeny of the dissorophid temnospondyls
The significance of osteoderms in dissorophid phylogeny is found to be much smaller than hitherto considered.
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.
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.
The first articulated skeleton of Dendrerpeton acadianum (Temnospondyli, Dendrerpetontidae) from the Lower Pennsylvanian locality of Joggins, Nova Scotia, and a review of its relationships
Although Dendrerpeton bears a general resemblance to the highly terrestrial dissorophoid temnospondyls and even shares with them a large squamosal embayment supported ventrally by the quadratojugal and a quadrate process, phylogenetic analysis does not support a sister-group relationship.
A reassessment of the temnospondyl amphibian Perryella olsoni from the Lower Permian of Oklahoma

The revised diagnosis and redescription of Perryella provide the basis for a re-evaluation of its systematic affinities and support a single origin for temnospondyls.
A New Amphibamid (Temnospondyli: Dissorophoidea) from the Early Permian of Texas
A new genus and species of amphibamid, Rubeostratilia texensis, represented by a skull from the Early Permian of Texas, shows many similarities with a recent described species from Richards Spur, Oklahoma, Pasawioops mayi.
A new trematopsid amphibian (Temnospondyli: Dissorophoidea) from the Lower Permian of Texas
Phonerpeton is interpreted as a small, lightly built, terrestrially adapted carnivore, and is distinguished by the presence of a semilunar curvature of the squamosal, domed parietals, an unossified sphenethmoid, long and slender mid-dorsal ribs, and a radius with a semicircular cross section.
The phylogeny of the ‘higher’ temnospondyls (Vertebrata: Choanata) and its implications for the monophyly and origins of the Stereospondyli
It is suggested that the radiation of the diverse stereospondyl clades, the Capitosauria and Trematosauria, began in the Late Permian of Gondwana, in a «safe haven» that was less severely affected by the LatePermian extinction event.
Trimerorhachis (Amphibia: Temnospondyli) from the Lower Permian of Texas and New Mexico: cranial osteology, taxonomy and biostratigraphy
The morphology and taxonomy of the Early Permian temnospondyl amphibian genus Trimerorhachis are revised, and numerous details of the cranial osteology of T. insignis Cope, 1878 are redescribed.
