Carpus and tarsus of Temnospondyli [PDF]
Vertebrate Anatomy, Morphology, Palaeontology, 2015 The carpus of Eryops megacephalus and tarsus of Acheloma cumminsi known from complete and articulated individuals have provided the standard anatomy of these skeletal regions for temnospondyls.

Pentadactyl manus of the Metoposaurus krasiejowensis from the Late Triassic of Poland, the first record of pentadactyly among Temnospondyli [PDF]
Journal of Anatomy, 2020 Metoposaurus krasiejowensis from the Late Triassic of Poland shows a unique for Temnospondyli structure of the manus with five digits. Based on the distribution of pentadactyly vs. tetradactyly in the temnospondyl manus, the number of digits was not phylogenetically constrained in temnospondyls, similar to today's amphibians. Abstract Temnospondyli are

Mandible histology in Metoposaurus krasiejowensis (Temnospondyli, Stereospondyli) from the Upper Triassic of Poland [PDF]
PeerJ, 2021 Recent studies that have systematically augmented our knowledge of dermal bones of the Late Triassic temnospondyl amphibian Metoposaurus krasiejowensis have mostly focused on shoulder girdle elements and the skull.

Returning to the roots: resolution, reproducibility, and robusticity in the phylogenetic inference of Dissorophidae (Amphibia: Temnospondyli) [PDF]
PeerJ, 2021 The phylogenetic relationships of most Paleozoic tetrapod clades remain poorly resolved, which is variably attributed to a lack of study, the limitations of inference from phenotypic data, and constant revision of best practices.

A supertree of Temnospondyli: cladogenetic patterns in the most species-rich group of early tetrapods [PDF]
Proceedings of the Royal Society B: Biological Sciences, 2007 As the most diverse group of early tetrapods, temnospondyls provide a unique opportunity to investigate cladogenetic patterns among basal limbed vertebrates. We present five species-level supertrees for temnospondyls, built using a variety of methods.

To be or not to be heavier: The role of dermal bones in the buoyancy of the Late Triassic temnospondyl amphibian Metoposaurus krasiejowensis. [PDF]
J Anat, 2022 First ever analysis of bone compactness in the pectoral girdle of large Late Triassic temnospondyl amphibian. Metoposaurids are known to possess large heavy dermal bones in their pectoral girdle that could have been selected for hydrostatic buoyancy control which helped them lead a bottom dwelling mode of life as historically hypothesized.

Early amphibians evolved distinct vertebrae for habitat invasions. [PDF]
PLoS ONE, 2021 Living tetrapods owe their existence to a critical moment 360-340 million years ago when their ancestors walked on land. Vertebrae are central to locomotion, yet systematic testing of correlations between vertebral form and terrestriality and subsequent ...

Illuminating the dark mess of fibers: Application of circular cross polarized light in unravelling the bone tissue structure of the dermal pectoral girdle of Metoposaurus krasiejowensis. [PDF]
J AnatCircular cross polarized light reveals the fine stucture of dermal bone tissue of a metoposaurid amphibian from the Late Triassic. Top right image shows the looped interwoven fibered bone when illuminated with circular polarized light displaying increased bone matrix intricacy compared to the same region of the bone when visualized with traditional ...
