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

The ability to live underground is widespread among continental vertebrates, so
understanding the origin and early evolution of fossorial vertebrates and the architecture …

The southern part of the Karoo Basin of South Africa contains a near complete stratigraphic
record of the Permo-Triassic boundary (PTB). Isotope-and magneto-stratigraphy confirm that …

Dinosauria debuted on Earth's stage in the aftermath of the Permo-Triassic Mass Extinction
Event, and survived two other Triassic extinction intervals to eventually dominate terrestrial …

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) …

Dicynodontia represent the most diverse tetrapod group during the Late Permian. They
survived the Permo-Triassic extinction and are central to understanding Permo-Triassic …

Here, we describe the dicynodont Lisowicia bojani, from the Late Triassic of Poland, a
gigantic synapsid with seemingly upright subcursorial limbs that reached an estimated …

Background Dysalotosaurus lettowvorbecki is a small ornithopod dinosaur known from
thousands of bones and several ontogenetic stages. It was found in a single locality within …

We present a detailed histological study of long bones from an ontogenetic series of
Mussaurus patagonicus, an early sauropodomorph from the Lower Jurassic of Argentina …

The bone histology of gorgonopsian, therocephalian and cynodont genera, ranging from the
Late Permian to Early Jurassic, was examined. The analysis reveals a predominance of …
