The cranial anatomy of Kombuisia frerensis Hotton (Synapsida, Dicynodontia) and a new phylogeny of anomodont therapsids [PDF]

open access: yesZoological Journal of the Linnean Society, 2007
Redescription of the small Triassic dicynodont Kombuisia frerensis Hotton reveals new information about its cranial anatomy. On the basis of the new data, the previously suggested hypothesis of a close relationship of Kombuisia and the Permian genus Kingoria is tested within a phylogenetic framework.

Evolution of the temporal skull openings in land vertebrates: A hypothetical framework on the basis of biomechanics

open access: yesThe Anatomical Record, Volume 307, Issue 4, Page 1559-1593, April 2024.
Abstract The complex constructions of land vertebrate skulls have inspired a number of functional analyses. In the present study, we provide a basic view on skull biomechanics and offer a framework for more general observations using advanced modeling approaches in the future.
