Capitosaurs were the largest and homogeneous group of Triassic temnospondyl amphibians with cosmopolitan distribution. However, their interrelationships are debated. The first capitosaur cranial remains found in the Iberian Peninsula were assigned to Parotosuchus; herein, a re-description of this material, together with information on other remains recovered from the same site, enables us to classify them as a new genus: Calmasuchus acri gen. et sp. nov. (Amphibia: Temnospondyli) from the early… 
A New Capitosauroid Temnospondyl from the Middle Triassic Upper Fremouw Formation of Antarctica
TLDR
A new capitosauroid temnospondyl is described from the upper Fremouw Formation of Antarctica on the basis of a large and relatively complete skull, characterized by its possession of numerous, extremely small maxillary, palatine, and ectopterygoid teeth, a dental pattern that suggests specialization on small prey items, possibly invertebrates.
A capitosauroid from the Lower Triassic of South America (Sanga do Cabral Supersequence: Paraná Basin), its phylogenetic relationships and biostratigraphic implications
Abstract Surviving through the end-Permian mass extinction, stereospondyls reemerged reaching a widespread distribution during the Early Triassic. A well representative lineage of this clade,
A new species of Cyclotosaurus (Stereospondyli, Capitosauria) from the Late Triassic of Bielefeld, NW Germany, and the intrarelationships of the genus
TLDR
A phylogenetic analysis of seven Cyclotosaurus species, including C. buechneri, and eight further capitosaur taxa with the Rhinesuchidae as an outgroup finds a monophyletic cyclotosaurus, which is the sister group of the Heylerosaurinae.
A potential record of a procolophonid parareptile from the Triassic of the Iberian Peninsula
Cranial and postcranial remains from the Middle Triassic of the Northeastern part of the Iberian Peninsula are reported and tentatively assigned to Procolophonidae. The finding is the first
A diverse Late Triassic tetrapod fauna from Manzanera (Teruel, Spain)
Abstract Several outcrops with vertebrate tetrapod remains have been located in the Keuper levels (Carnian, Upper Triassic) of the Spanish municipality of Manzanera (Teruel Province). The Manzanera
First direct archosauromorph remains from the Early-Middle Triassic transition of the Iberian Peninsula
This paper discusses the taxonomic affinities of three isolated teeth discovered in the Buntsandstein facies of the Catalan Coastal Ranges and central-eastern Pyrenean basins that crop out in
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
Palaeoecology of Middle Triassic tetrapod ichnoassociations (middle Muschelkalk, NE Iberian Peninsula) and their implications for palaeobiogeography in the western Tethys region
Abstract Tetrapod ichnology is a powerful tool to reconstruct the faunal composition of Middle Triassic ecosystems. However, reconstructions based on a single palaeoenvironment provide an incomplete

TLDR
Analysis of a new capitosaur phylogenetic data matrix, containing 56 characters and 29 species, confirms that the two species from Yuanan are sister taxa and that Capitosauroidea can be divided into two major clades.

Abstract. The non-marine Mesozoic sedimentary rocks of Thailand, which consist of the Indochina block and the Sibumasu block, have yielded several terrestrial and aquatic vertebrate fossils, but only

The phylogeny of the largest amphibians, the Triassic capitosaurs, is still much debated. One key taxon for the understanding of their relationships, Odenwaldia heidelbergensis from the Buntsandstein
The Origin And Intrarelationships Of Triassic Capitosaurid Amphibians
TLDR
The traditional view that MastodonsaurusEocyclotosaurus are sister taxa of Benthosuchus is demonstrated to be based on highly variable and/or homoplastic features, whose ancestral condition is moreover uncertain.
A REVISION OF THE EARLY TRIASSIC “CAPITOSAURS” (STEGOCEPHALI, STEREOSPONDYLI) FROM MADAGASCAR, WITH REMARKS ON THEIR COMPARATIVE ONTOGENY

A phylogenetic analysis showed that the genus Watsonisuchus is justified, although its species W. madagascariensis is not the most derived within the genus.

TLDR
A preliminary phylogenetic analysis of trematosauroid relationships confirms that Benthosuchus is a basal treMatosaurian rather than a basal mastodonsauroid, and that ThoosuchUS is the sister group to all other trematOSauroids.
The temnospondyl amphibian Cyclotosaurus from the Upper Triassic of Poland
A gap in the Late Triassic fossil record of the capitosaur amphibian Cyclotosaurus is filled by new material from lacustrine deposits at Krasiejow, Poland, corresponding in age to the Lehrberg Beds
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.
The phylogeny of the ‘higher’ temnospondyls (Vertebrata: Choanata) and its implications for the monophyly and origins of the Stereospondyli
TLDR
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.

TLDR
A phylogenetic analysis of the trematosaurs is performed for the first time and suggests that Wantzosaurus is a derived taxon within the clade Trematosauridae, the family is defined on the basis of derived character states and is shown to be monophyletic.

TLDR
This species is shown to be markedly advanced over the Parotosuchus level in the structure of the tabulars and the postglenoid division of the lower jaw, in the shape of the posterior rim of the mandibular adductor fossa, and in the strong development of the medial plate of the surangular.
