Triassic vertebrate tracks are known fromthe beginning of the 19th century and have a worldwide distribution. Several Triassic track ichnoassemblages and ichnotaxa have a restricted stratigraphic range and are useful in ...

For more than 30 million years, in early Mesozoic Pangea, ""rauisuchian"" archosaurs were the apex predators in most terrestrial ecosystems, but their biology and evolutionary history remain poorly understood. We describe ...

The Brachyopoidea is a group of Mesozoic temnospondyls with flat, parabolic skulls that were recently reviewed and considered to include Brachyopoidea and Chigutisauridae (Warren and Marsicano, 2000; Yates and Warren, 2000, ...

Background: Archosauromorpha originated in the middle–late Permian, radiated during the Triassic, and gave rise to the crown group Archosauria, a highly successful clade of reptiles in terrestrial ecosystems over the last ...

Darwinulocopina is an interesting group of ostracods that includes some of the first invaders of freshwater habitats during the late Palaeozoic. The Permian–Triassic extinction greatly reduced their diversity, culminating ...

The salle Grylloblattidae or Grylloblattodea order (extant representatives are referred to as ‘living fossils’ and have relictual distributions) is one of the least diverse extant insect groups (with 29 species and five ...

We report here on the first tetrapod tracks from the Triassic of the Nurra region (north-western Sardinia, Italy). The specimens were found on sandstone blocks used to build a fence limiting a seasonal camping, in the ...

Erythrosuchidae is a clade of early archosauriform reptiles, which were apex predators in many late Early and Middle Triassic ecosystems, following the Permo-Triassic mass extinction. Erythrosuchids had a worldwide ...
