Unexpected Early Triassic marine ecosystem and the rise of the Modern evolutionary fauna
Science Advances, 2017 A new marine fossil assemblage from the Early Triassic shows unexpected phyletic diversity and functional complexity. In the wake of the end-Permian mass extinction, the Early Triassic (~251.9 to 247 million years ago) is portrayed as an environmentally ...

An overview of the postcranial osteology of caecilians (Gymnophiona, Lissamphibia)
The Anatomical Record, EarlyView.Abstract Caecilians comprise a relatively small (~220 species) group (Gymnophiona) of snake‐like or worm‐like, mostly tropical amphibians. Most adult caecilians are fossorial, although some species may live in aquatic or semi‐aquatic environments, either as larvae or adults.

The Khadzhokh Canyon System—An Important Geosite of the Western Caucasus
Geosciences, 2020 True diversity of geological heritage sites (geosites) is yet to be fully understood. New field studies of the Khadzhokh Canyon and its vicinities in the Western Caucasus (Mountainous Adygeya tourist destination, southwestern Russia) have allowed ...

Decoupled taxonomic and ecological recoveries from the Permo-Triassic extinction
Science Advances, 2018 After the enormous Permian-Triassic mass extinction, marine animals high in the food chain recovered the most quickly. The Permian-Triassic mass extinction was the worst crisis faced by life; it killed >90% of marine species in less than 0.1 million ...

The Anatomical Record, EarlyView.Abstract Dinosaurs evolved a unique respiratory system with air sacs that contributed to their evolutionary success. Postcranial skeletal pneumaticity (PSP) has been used to infer the presence of air sac systems in some fossil archosaurs. While unambiguous evidence of PSP is well documented in pterosaurs and post‐Carnian saurischians, it remains absent

The earliest equatorial record of frogs from the Late Triassic of Arizona
Biology Letters, 2019 Crown-group frogs (Anura) originated over 200 Ma according to molecular phylogenetic analyses, though only a few fossils from high latitudes chronicle the first approximately 60 Myr of frog evolution and distribution.

The Anatomical Record, EarlyView.Abstract Dicynodonts (Anomodontia: Dicynodontia) were one of the main groups of terrestrial tetrapods in Permian and Triassic faunas. In Brazil, the genus Dinodontosaurus is one of the most common tetrapod taxon in the Triassic Santa Maria Supersequence. This genus has a complex taxonomic history and is represented in the Triassic of both Argentina and
