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.

Morphology of the canine and precanine dentition in the gomphodont cynodonts (Synapsida, Cynodontia, Gomphodontia) from the Triassic of South America

open access: yes, 2022
En la presente tesina se plantea como hipótesis que las morfologías de los caninos e incisivos de los cinodontes gonfodontes (Synapsida, Cynognathia) descubiertos en América del Sur son más variadas que lo que se postuló hasta el momento.

The origin and evolution of Cynodontia (Synapsida, Therapsida): Reassessment of the phylogeny and systematics of the earliest members of this clade using 3D‐imaging technologies

open access: yesThe 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

open access: yesEuropean 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.

Forelimb Shape, Disparity, and Functional Morphology in the Deep Evolutionary History of Synapsida [PDF]

open access: yes, 2020
Mammals and their closest fossil relatives use their shoulders and forelimbs for many functions, which is reflected by the great range of mammalian forelimb shapes.

Selection towards larger body size in both herbivorous and carnivorous synapsids during the Carboniferous

open access: yesFACETS, 2017
Body size is one of the most important characteristics of an organism, impacting a great variety of ecological characteristics. The influence of diet on body size has received considerable attention, with previous studies suggesting a greater tendency ...
