Phylogeny of Paleozoic limbed vertebrates reassessed through revision and expansion of the largest published relevant data matrix [PDF]
PeerJ, 2019 The largest published phylogenetic analysis of early limbed vertebrates (Ruta M, Coates MI. 2007. Journal of Systematic Palaeontology 5:69–122) recovered, for example, Seymouriamorpha, Diadectomorpha and (in some trees) Caudata as paraphyletic and found ...

Comparative 3D analyses and palaeoecology of giant early amphibians (Temnospondyli: Stereospondyli). [PDF]
Sci Rep, 2016 AbstractMacroevolutionary, palaeoecological and biomechanical analyses in deep time offer the possibility to decipher the structural constraints, ecomorphological patterns and evolutionary history of extinct groups. Here, 3D comparative biomechanical analyses of the extinct giant early amphibian group of stereospondyls together with living ...

Review of the tetrapod skull-neck boundary: implications for the evolution of the atlas-axis complex. [PDF]
Biol Rev Camb Philos SocABSTRACT This review describes variation in modern and fossil occiput–atlas–axis complex anatomy of total group Tetrapoda with the aim of documenting the range of structural variation throughout their evolutionary history to establish grounds for comparison of the complex between tetrapod clades.

Synapsids and sensitivity: Broad survey of tetrapod trigeminal canal morphology supports an evolutionary trend of increasing facial tactile specialization in the mammal lineage. [PDF]
Anat Rec (Hoboken)Abstract The trigeminus nerve (cranial nerve V) is a large and significant conduit of sensory information from the face to the brain, with its three branches extending over the head to innervate a wide variety of integumentary sensory receptors, primarily tactile.

Ornamentation of dermal bones of Metoposaurus krasiejowensis and its ecological implications [PDF]
PeerJ, 2018 Background Amphibians are animals strongly dependent on environmental conditions, like temperature, water accessibility, and the trophic state of the reservoirs.

Unique bone histology of modern giant salamanders: a study on humeri and femora of Andrias spp. [PDF]
Zoological LettersThe osteohistology of Andrias spp. is a pivotal analogue for large fossil non-amniotes (e.g., Temnospondyli), and the endangered status of this taxon underlines the importance of gathering information on its growth.

Cautionary tales on the use of proxies to estimate body size and form of extinct animals. [PDF]
Ecol EvolReconstructing the body size and form of extinct animals is of vital importance to our understanding of macroevolution and palaeontology. This is often done using anatomical proxies where extinct species are known only from fragmentary remains. However, there are many limitations influencing the selection of proxy taxa that are frequently overlooked ...

Histological characterization of denticulate palatal plates in an Early Permian dissorophoid [PDF]
PeerJ, 2017 Denticles are small, tooth-like protrusions that are commonly found on the palate of early tetrapods. Despite their widespread taxonomic occurrence and similar external morphology to marginal teeth, it has not been rigorously tested whether denticles are

Skull Mechanics and the Evolutionary Patterns of the Otic Notch Closure in Capitosaurs (Amphibia: Temnospondyli) [PDF]
Anatomical Record, 2012 AbstractCapitosaurs were among the largest amphibians that have ever lived. Their members displayed an amphibious lifestyle. We provide new information on functional morphology data, using finite element analysis (FEA) which has palaeoecological implications for the group. Our analyses included 17 taxa using (2D) plate models to test four loading cases
