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.

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 First Healed Bite Mark and Embedded Tooth in the Snout of a Middle Permian Gorgonopsian (Synapsida: Therapsida) [PDF]
Frontiers in Ecology and Evolution, 2021 Despite their significance for paleobiological interpretations, bite marks have been rarely reported in non-mammalian therapsids (NMT). Here we describe, for the first time, the occurrence of a tooth embedded in the snout of a gorgonopsian.

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.

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.

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.

Rise of dinosaurs reveals major body-size transitions are driven by passive processes of trait evolution. [PDF]
Proc Biol Sci, 2012 A major macroevolutionary question concerns how long-term patterns of body-size evolution are underpinned by smaller scale processes along lineages.
