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

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.

Figure 10 in Braincase evolution in suchian archosaurs (Reptilia: Diapsida): evidence from the rauisuchian Batrachotomus kupferzellensis

, 2002
Figure 10. Strict consensus tree of five most parsimonious trees (MPTs) retrieved by parsimony analysis of data in Table 1. These MPTs have a length of 37 steps, a consistency index of 0.811, and a retention index of 0.889.

A redescription of Brouffia orientalis Carroll & Baird, 1972 from the Upper Carboniferous of the Czech Republic and the status and affinities of protorothyridid amniotes

Swiss Journal of Palaeontology
The Upper Carboniferous protorothyridid amniote Brouffia orientalis from Czech Republic is redescribed. Photogrammetric scanning of the holotype and only known specimen yields considerable new information on the skull and postcranium of this tetrapod and
