Palaeoneurology and palaeobiology of the dinocephalian therapsid Anteosaurus magnificus
Dinocephalians (Therapsida), some of the earliest amniotes to have evolved large body size, include the carnivorous Anteosauria and mostly herbivorous Tapinocephalia. Whilst the palaeoneurology of
Body mass estimation in Triassic cynodonts from Argentina based on limb variables
in from based on Body mass estimations for extinct taxa are fundamental in palaeobiological reconstructions, but little work has been done on this topic for non-mammaliaform cynodonts (NMC), the
A New Large Gomphodont from the Triassic of South Africa and Its Implications for Gondwanan Biostratigraphy
ABSTRACT A partial skull (BP/1/7976) of a very large cynodont from the Middle Triassic Cynognathus Assemblage Zone (Cricodon-Ufudocyclops subzone) of South Africa is described. The specimen
Can maxillary canal morphology inform varanopid phylogenetic affinities?
TLDR
The maxillary canals of Orovenator and Prolacerta are very similar and differ markedly from those of Heleosaurus and Varanosaurus, which could support the traditional position of varanopids among the Synapsida.
Cranial anatomy of Bolotridon frerensis, an enigmatic cynodont from the Middle Triassic of South Africa, and its phylogenetic significance
TLDR
A computed tomographic reconstruction of BSPG 1934-VIII-7 represents by far the most extensive specimen of B. frerensis, providing novel information on its palatal and internal anatomy and recovering Bolotridon as the sister-taxon of Eucynodontia.
Distributions of extinction times from fossil ages and tree topologies: the example of mid-Permian synapsid extinctions
TLDR
The timing of extinctions of these three Permo-Carboniferous synapsid taxa and of their component lineages supports the idea that the biological crisis in the late Kungurian/early Roadian consisted of a progressive decline in biodiversity throughout the Kungurians.
Distributions of extinction times from fossil ages and tree topologies: the example of some mid-Permian synapsid extinctions
Given a phylogenetic tree that includes only extinct, or a mix of extinct and extant taxa, where at least some fossil data are available, we present a method to compute the distribution of the
Elevated Cranial Sutural Complexity in Burrowing Dicynodonts

TLDR
Increased sutural complexity, rather than cranial fusion, as an adaptation to resisting compressive forces during burrowing may be related to indeterminate growth in dicynodonts.
