Early synapsids neurosensory diversity revealed by CT and synchrotron scanning. [PDF]
Anat Rec (Hoboken)Abstract Non‐mammaliaform synapsids (NMS) represent the closest relatives of today's mammals among the early amniotes. Exploring their brain and nervous system is key to understanding how mammals evolved. Here, using CT and Synchrotron scanning, we document for the first time three extreme cases of neurosensory and behavioral adaptations that probe ...

Tetrapod tracks in Permo–Triassic eolian beds of southern Brazil (Paraná Basin) [PDF]
PeerJ, 2018 Tetrapod tracks in eolianites are widespread in the fossil record since the late Paleozoic. Among these ichnofaunas, the ichnogenus Chelichnus is the most representative of the Permian tetrapod ichnological record of eolian deposits of Europe, North ...

An early geikiid dicynodont from the Tropidostoma Assemblage Zone (late Permian) of South Africa [PDF]
PeerJ, 2017 Based on specimens previously identified as Tropidostoma, a new taxon of dicynodont (Bulbasaurus phylloxyron gen. et sp. nov.) from the Karoo Basin of South Africa is described.

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 ...

Bringing dicynodonts back to life: paleobiology and anatomy of a new emydopoid genus from the Upper Permian of Mozambique. [PDF]
PLoS ONE, 2013 Dicynodontia represent the most diverse tetrapod group during the Late Permian. They survived the Permo-Triassic extinction and are central to understanding Permo-Triassic terrestrial ecosystems.

Elevated Cranial Sutural Complexity in Burrowing Dicynodonts
Frontiers in Ecology and Evolution, 2021 Relationships between the complexity of the cranial sutures and the inferred ecology of dicynodont synapsids are explored. Simple complexity indices based on degree of sutural interdigitation were calculated for 70 anomodont species and indicate that the
