Cranial anatomy of the gorgonopsian Cynariops robustus based on CT-reconstruction [PDF]
PLoS ONE, 2018 Gorgonopsia is one of the major clades of non-mammalian synapsids, and includes an array of large-bodied carnivores that were the top terrestrial predators of the late Permian. Most research on the clade has focused on these largest members; small-bodied

The postcranial anatomy of Gorgonops torvus (Synapsida, Gorgonopsia) from the late Permian of South Africa [PDF]
PeerJ, 2023 Gorgonopsians are among the most recognizable groups of synapsids from the Permian period and have an extensive but mostly cranial fossil record. By contrast, relatively little is known about their postcranial anatomy. Here, we describe a nearly complete,

Systematics of the Rubidgeinae (Therapsida: Gorgonopsia) [PDF]
PeerJ, 2016 The subfamily Rubidgeinae, containing the largest known African gorgonopsians, is thoroughly revised. Rubidgeinae is diagnosed by the absence of a blade-like parasphenoid rostrum and reduction or absence of the preparietal.

Gorgonopsian therapsids (Nochnitsa gen. nov. and Viatkogorgon) from the Permian Kotelnich locality of Russia [PDF]
PeerJ, 2018 The early evolution of gorgonopsians is poorly understood. New material from the Kotelnich locality in Russia expands our knowledge of middle/earliest late Permian gorgonopsians from Laurasia.

Whole-body endothermy: ancient, homologous and widespread among the ancestors of mammals, birds and crocodylians. [PDF]
Biol Rev Camb Philos Soc, 2022 ABSTRACT The whole‐body (tachymetabolic) endothermy seen in modern birds and mammals is long held to have evolved independently in each group, a reasonable assumption when it was believed that its earliest appearances in birds and mammals arose many millions of years apart.

Rethinking therapsid phylogeny through Bayesian and cladistic approaches [PDF]
Scientific ReportsTherapsids are early-diverging synapsids that thrived during the Permian and Triassic periods, and ultimately gave rise to mammals. They include six major groups, which already exhibited considerable diversity at their first appearance in the fossil ...

Hypercanines: Not just for sabertooths. [PDF]
Anat Rec (Hoboken)Abstract Hypercanines are here defined as hypertrophied caniniform teeth, that is, canine teeth that are elongated to serve specific functions in different clades of mammals and their synapsid ancestors. This article presents an overview of the occurrence of hypercanines, their growth, and their function across a broad range of clades.

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 ...

The osteohistology of gorgonopsian therapsids and implications for Permo-Triassic theriodont growth. [PDF]
J AnatPermian gorgonopsian therapists had rapid, annually interrupted growth and show longer lifespans than early Triassic therapists. Abstract During the Late Permian, saber‐toothed gorgonopsian therapsids were the dominant terrestrial predators, playing crucial roles as apex predators alongside therocephalian therapsids within Permian terrestrial ...

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.
