The late Palaeozoic is a pivotal period for the evolution of terrestrial ecosystems.
Generalised warming and aridification trends resulted in profound floral and faunal turnover …

Anomodont synapsids represent the dominant herbivores of Permian and Triassic terrestrial
vertebrate ecosystems. Their taxonomic diversity and morphological disparity in combination …

Mammals are arguably the most conspicuous tetrapods in the modern biota. Although there
are fewer extant mammal species (~ 5,500) than birds (~ 10,000) or squamates (~ 10,000) …

Until recently, the Guadalupian (middle Permian) tetrapod fossil record was known almost
exclusively from the Karoo Basin of South Africa and the Cis-Urals region of Russia, limiting …

Therapsids were a dominant component of middle–late Permian terrestrial ecosystems
worldwide, eventually giving rise to mammals during the early Mesozoic. However, little is …

Pangaean paleogeographic models place the Tim Mersoi basin of northern Niger in a 5000-
km-wide corridor between Gondwana and Laurasia approximately 15 degrees south of the …

For much of its history, the fossil record of burnetiamorph therapsids was both species poor
and known from very few specimens. By contrast, the past two decades have seen a …

Climate models indicate increased desertification in the continental interior of Pangea
during the Permian, which would have affected the composition of the flora and fauna. We …

Pareiasaurs were a group of herbivorous reptiles that lived during the middle to late Permian
(˜ 265–252 Ma) in what is modern-day Europe, Asia, South America, and Africa. Field work …

Recent field work in the upper Permian Moradi Formation of Niger has yielded new material
of the late-occurring and largest moradisaurine captorhinid, Moradisaurus grandis. The …
