Cranial Bosses of Choerosaurus dejageri (Therapsida, Therocephalia): Earliest Evidence of Cranial Display Structures in Eutheriodonts. [PDF]

PLoS ONE, 2016
Choerosaurus dejageri, a non-mammalian eutheriodont therapsid from the South African late Permian (~259 Ma), has conspicuous hemispheric cranial bosses on the maxilla and the mandible.

Description of the skull, braincase, and dentition of Moschognathus whaitsi (Dinocephalia, Tapinocephalia), and its palaeobiological and behavioral implications. [PDF]

Anat Rec (Hoboken)
Abstract A subadult Moschognathus whaitsi from the Eastern Cape Province, South Africa, was scanned using synchrotron radiation X‐ray computed tomography (SRXCT). Its subadult state allowed the cranial bones and teeth to be identified and individually reconstructed in 3D.

Oxygen isotopes suggest elevated thermometabolism within multiple Permo-Triassic therapsid clades

, 2016
International audienceNowadays, birds and mammals are the only true endothermic homeothermic animals. They produce and regulate their internal temperature quite independently from ambient environmental temperatures.

The First Healed Bite Mark and Embedded Tooth in the Snout of a Middle Permian Gorgonopsian (Synapsida: Therapsida)

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.

Morphology of the temporal skull region in tetrapods: research history, functional explanations, and a new comprehensive classification scheme

Biological Reviews, Volume 96, Issue 5, Page 2229-2257, October 2021., 2021
ABSTRACT The morphology of the temporal region in the tetrapod skull traditionally has been a widely discussed feature of vertebrate anatomy. The evolution of different temporal openings in Amniota (mammals, birds, and reptiles), Lissamphibia (frogs, salamanders, and caecilians), and several extinct tetrapod groups has sparked debates on the ...

A Summary of the Gorgonopsia and its Members [PDF]

, 2021
Gorgonopsids were a group of Therapsids that lived from the mid to late Permian. They were the dominant predators in their ecosystem. Their remains are found primarily in the South African Karoo Basin, and parts of Eastern Russia.

Cranial osteology and reassessment of the historically collected South African gorgonopsians FMNH UC 1513 (Lycaenops cf. L. angusticeps) and AMNH FARB 5537 (Lycaenops angusticeps)

Vertebrate Anatomy, Morphology, Palaeontology
Lycaenops contains one of the most anatomically complete gorgonopsian specimens (AMNH FARB 2240) known and is thought to represent one of the more taxonomically diverse forms, with several species historically attributed to it.

Relative growth and morphological variation in the skull of Aelurognathus (therapsida: gorgonopsia) [PDF]

, 2013
Gorgonopsia represent a group of specialised carnivorous therapsids that filled the role of apex predator during the Late Permian of Gondwana. Skull size in the Gorgonopsia ranges from that of a cat, to larger than any extant, terrestrial predator ...

Inostrancevia africana, the first diagnosable gorgonopsian (Therapsida, Synapsida) from the Metangula graben (Mozambique): new anatomical observations and biostratigraphic implications

Swiss Journal of Palaeontology
The diversity of the fauna of the late Permian K6 Formation of the Metangula graben of northern Mozambique is coming to light thanks to recent discoveries made by the PaleoMoz Project.
