Abstract The Permian-Triassic mass extinction (PTME, ca. 252 Mya) was one of the most
severe biotic crises of the Phanerozoic, eliminating> 90% of marine and terrestrial species …

The early evolution of archosauromorphs during the Permo-Triassic constitutes an excellent
empirical case study to shed light on evolutionary radiations in deep time and the timing and …

Sauria is the crown-group of Diapsida and is subdivided into Lepidosauromorpha and

The replacement of the basal synapsid pelycosaurs by the more 'mammal‐like'therapsids in
the Permian was an important event in the history of tetrapods because it initiated the …
