Tiarajudens eccentricus and Anomocephalus africanus, two bizarre anomodonts (Synapsida, Therapsida) with dental occlusion from the Permian of Gondwana [PDF]
Royal Society Open Science, 2015 Anomodontia was a highly successful tetrapod clade during the Permian and the Triassic. New morphological information regarding two bizarre basal anomodonts is provided and their palaeoecological significance is explored.

The 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.

Does a Cadillac engine need a biological and phylogenetic explanation? [PDF]
, 2016 In this text we briefly explore whether ridiculing material objects like a ‘Cadillac engine’, a ‘desk’, ‘gold bars in a vault’ as reduction ad absurdum in ‘dialectical duels’ or as a metaphor for teaching evolution is really phylogenetically justified,

The Anatomical Record, Volume 307, Issue 4, Page 1634-1730, April 2024.Abstract The origin of cynodonts, the group ancestral to and including mammals, is one of the major outstanding problems in therapsid evolution. One of the most troubling aspects of the cynodont fossil record is the lengthy Permian ghost lineage between the latest possible divergence from its sister group Therocephalia and the first appearance of ...

A mammal and bird's‐eye‐view of the pupil during sleep and wakefulness
European Journal of Neuroscience, Volume 59, Issue 4, Page 584-594, February 2024.The pupil size of mammals and birds varies as a function of brain state during wakefulness and sleep; however, in an opposite way. This raises the possibility that state‐dependent changes in pupil size are a window into different brain processes in birds compared with mammals.

Aspects of gorgonopsian paleobiology and evolution: insights from the basicranium, occiput, osseous labyrinth, vasculature, and neuroanatomy [PDF]
PeerJ, 2017 Synapsida, the clade including therapsids and thus also mammals, is one of the two major branches of amniotes. Organismal design, with modularity as a concept, offers insights into the evolution of therapsids, a group that experienced profound anatomical

On the Lystrosaurus zone and its fauna with special reference to some immature Lystrosauridae [PDF]
, 1968 Main articleIn the past, collecting from the middle Beaufort Beds or Lystrosaurus zone has been badly neglected by field workers mainly due to the monotonous occurrence of the genus Lystrosaurus.

The first tritylodontid (Synapsida, Cynodontia) fossil from Scandinavia.
Bulletin of the Geological Society of DenmarkLower Jurassic (Pliensbachian) sand- and siltstones of the Hasle Formation on the Danish Island of Bornholm have yielded a diverse invertebrate and vertebrate assemblage dominated by marine taxa. Recently, dental and skeletal remains of terrestrial animals have also been collected from this rock unit, including the first tritylodontid tooth from ...
