Abstract The plagiosaurine Gerrothorax pulcherrimus, a ubiquitous faunal component of the Fleming Fjord Formation, is recognized by tubercular ornamentation, contact between the postfrontal and supratemporal, at least two tooth rows on the posterior coronoid, and a posttemporal fenestra that is small or absent. Gerrothorax pulcherrimus also possesses a derived pectoral morphology that includes an interlocking claviculocleithral complex and an interclavicle with paired posterolateral projections… 
Cranial morphology of the plagiosaurid Gerrothorax pulcherrimus as an extreme example of evolutionary stasis
TLDR
The eco-logical interpretation for G. pulcherrimus is that it relied on the permanent presence of water, but was accessible with respect to the size and nature of the water body as well as to changes in salinity, and the unparalleled extent of evolutionary stasis may therefore be based on the ecologicalexibility of this morphologically so tightly constrained temnospondyl.
Braincase, palatoquadrate and ear region of the plagiosaurid Gerrothorax pulcherrimus from the Middle Triassic of Germany
TLDR
Morphology of neurocranium and palatoquadratum of Gerrothorax most closely resembles that of the Russian plagiosaurid Plagiosternum danilovi, although the elements are more ossified in the latter and a strong endocranial ossification cannot be evaluated as a plesiomorphic character in basal tetrapods.
Cyclotosaurus naraserluki, sp. nov., a New Late Triassic Cyclotosaurid (Amphibia, Temnospondyli) from the Fleming Fjord Formation of the Jameson Land Basin (East Greenland)
ABSTRACT Cyclotosaurus naraserluki, sp. nov., is a new Late Triassic capitosaurid amphibian from lacustrine deposits in the Fleming Fjord Formation of the Jameson Land Basin in Greenland. It is
Cranial anatomy of the stem salamander Kokartus honorarius (Amphibia: Caudata) from the Middle Jurassic of Kyrgyzstan
TLDR
The morphological analysis of Kokartus supports the current phylogenetic hypothesis that Permian amphibamids (including branchiosaurids) are the closest relatives of salamanders amongst known non-lissamphibian temnospondyls.
A large temnospondyl humerus from the Rhaetian (Late Triassic) of Bonenburg (Westphalia, Germany) and its implications for temnospondyl extinction
Temnospondyls are a group of basal tetrapods that existed from the Early Carboniferous to the Early Cretaceous. They were characteristic members of Permian and Triassic continental faunas around the
Skull morphology and phylogenetic relationships of a new Middle Triassic plagiosaurid temnospondyl from Germany, and the evolution of plagiosaurid eyes
TLDR
Phylogenetic analysis finds plagiosaurids to be monophyletic within a broad range of temnospondyls, nesting within a clade of short-skulled stereospondys.
A New Eusuchian Crocodyliform with Novel Cranial Integument and Its Significance for the Origin and Evolution of Crocodylia
TLDR
A new, giant crocodyliform from the early Late Cretaceous (Cenomanian) Kem Kem Formation of Morocco is reported, found to be a derived eusuchian and sister taxon to Aegyptosuchus, which forms the sister clade of crown-group Crocodylia, making these taxa the earliest eUSuchian croc Codyliforms known from Africa.
Redescription of the phytosaurs Paleorhinus (‘Francosuchus’) angustifrons and Ebrachosuchus neukami from Germany, with implications for Late Triassic biochronology
TLDR
It is provided the first autapomorphy-based support for a monophyletic but restricted Paleorhinus (supported by a nodal row on the jugal, and low paired ridges on the squamosal) and confirmed that previous broader conceptions of Paleorlinus are likely to be paraphyletic.
Late Triassic capitosaurian remains from Svalbard and the palaeobiogeographical context of Scandinavian Arctic temnospondyls
Abstract The Norwegian Arctic Svalbard archipelago is famous for its prolific record of Early–Middle Triassic vertebrate fossils. These represent mainly marine amniotes, together with sharks, bony
Reconstruction of cranial and hyobranchial muscles in the triassic temnospondyl Gerrothorax provides evidence for akinetic suction feeding
TLDR
No cranial kinesis was possible in the Gerrothorax skull, and therefore suction feeding was not as elaborate as in these extant forms, and this reconstruction may guide future studies of feeding in extinct aquatic tetrapods with ossified hyobranchial apparatus.

The Last Labyrinthodont? A New Brachyopoid (Amphibia, Temnospondyli) from the Early Jurassic Evergreen Formation of Queensland, Australia
TLDR
The diversity of Australia's brachyopoids, including the presence of the most primitive and earliest-known members of each of the included families, suggests that the superfamily originated in Australia.
The postcranial skeleton of the Devonian tetrapod Tulerpeton curtum Lebedev
TLDR
A cladistic analysis indicates that Tulerpeton is a reptiliomorph stem-group amniote and the earliest known crown-group tetrapod: Acanthostega and Ichthyostega are successively more derived plesion stem- group tetrapods and do not consititute a monophyletic ichthyostegalian radiation.
The postcranial skeletal anatomy of the carboniferous tetrapod Greererpeton burkemorani Romer, 1969
TLDR
A cladistic analysis indicates that Greererpeton burkemorani shares a more recent common ancestor with the anthracosaur Proterogyrinus scheelei than it does with either Crassigyrinus scoticus or Ichthyostega sp.

TLDR
A relation between Peltobatrachus and the Triassic plagiosaurs is postulated on both cranial and postcranial characters, and it is concluded that they are not closely related to Dvinosaurus or to the metoposaurs.
DINOSAUR GASTRALIA; ORIGIN, MORPHOLOGY, AND FUNCTION
TLDR
The anatomy of the gastralial system indicates a more active function than abdominal support or protection, and may have been important for the evolution of the unidirectional airflow lung of birds.
Prey processing in Leurognathus marmoratus and the evolution of form and function in desmognathine salamanders (Plethodontidae)
TLDR
It is suggested that origin of the atlanto-mandibular ligaments can be considered a 'key innovation' in that it allowed the secondary invasion of stream habitats by adults of ancestral desmognathines.
Evolution of the Cervical Vertebrae in Temnospondyl Amphibians and Differentiation of the Early Tetrapods
TLDR
The loss of the atlantal rib in temnospondyls does not support the hypothesis of their specific affinity to micro- saurs and a number of mosaic trends which spread decreasingly in the craniocaudal direction within the anterior postcervical vertebrae.
A systematic revision and phylogenetic analysis of Triassic mastodonsauroids (Temnospondyli: Stereospondyli)
TLDR
The Mastodonsauroidea must have a ghost lineage extending back to at least the Late Permian, when the common ancestor of the MastodONsauridae and the Trematosauroid ancestors diverged from rhinesuchid ancestors.

Abstract A dermal bone fragment bearing a peculiar pustulate superficial ornamentation is recorded from the Upper Triassic (Norian) Huai Hin Lat Formation of northeastern Thailand. The specimen is
CHAPTER 3 – Aquatic Feeding in Salamanders
TLDR
As long as representatives of most of the major groups of salamanders can be obtained, technological advances in high-speed imaging, electromyography, muscle physiology, and neurophysiology will continue to provide opportunities to explore the form and function of the feeding systems ofSalamanders at multiple levels.
