The taxonomic status of Parathrinaxodon proops (Therapsida: Cynodontia), with comments on the morphology of the palate in basal cynodonts [PDF]

, 2005
The holotype and only specimen of Parathrinaxodon proops, a cynodont from the Upper Permian Kawinga Formation, Tanzania, is redescribed. Upper postcanines from the middle of the tooth row are ovoid in outline, presenting a large main cusp and tiny ...

Endocranial morphology of the Brazilian Permian dicynodont Rastodon procurvidens (Therapsida: Anomodontia) [PDF]

Journal of Anatomy, 2019
AbstractDicynodontia is a major clade of terrestrial tetrapods that greatly diversified during the Permian and Triassic periods, reaching a worldwide distribution. In this study, the endocranial cavity of the Brazilian Permian dicynodont Rastodon procurvidens is described based on a digital endocast obtained using digital imaging (X‐ray computed ...

Numerous independent gains of daily torpor and hibernation across endotherms, linked with adaptation to diverse environments

Functional Ecology, Volume 39, Issue 3, Page 824-839, March 2025.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Many endotherms from diverse taxonomic groups can respond to environmental changes through torpor, that is, by greatly reducing their energy expenditure for up to 24 hours (daily torpor) or longer (hibernation).

Первое свидетельство наличия осязательных сенсорных зон у дицинодонтов (therapsida)

Izvestiya of Saratov University. New Series. Series: Earth Sciences, 2006
Впервые получено свидетельство о формировании осязательных сенсорных зон у представителя нетериодонтных терапсид Myosaurus gracilis (Dicynodontia). Система отверстий и бороздок на верхнечелюстной кости свидетельствует о наличии хорошо развитой системы кровеносных сосудов на морде Myosaurus. Сходные структуры обычно связываются с развитием сенсорных зон

Youngest dinocephalian fossils extend the Tapinocephalus Zone, Karoo Basin, South Africa

South African Journal of Science, 2015
The dinocephalians (Synapsida, Therapsida) were one of the dominant tetrapod groups of the Middle Permian (Guadalupian Epoch, ~270–260 million years ago) and are most abundantly recorded in the Tapinocephalus Assemblage Zone (AZ) of the Main Karoo Basin,

Fossil Record, 2015
The Late Permian dicynodont Digalodon rubidgei Broom and Robinson, 1948, is redescribed based on reanalysis of the holotype and newly recognized referable specimens.

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.

Testing extinction events and temporal shifts in diversification and fossilization rates through the skyline Fossilized Birth‐Death (FBD) model: The example of some mid‐Permian synapsid extinctions

Cladistics, Volume 40, Issue 3, Page 282-306, June 2024.
Abstract In the last decade, the Fossilized Birth–Death (FBD) process has yielded interesting clues about the evolution of biodiversity through time. To facilitate such studies, we extend our method to compute the probability density of phylogenetic trees of extant and extinct taxa in which the only temporal information is provided by the fossil ages ...
