Recovery of gastropods in the Early Triassic

Comptes Rendus Palevol, 2005
Abstract Gastropod rebound from the end-Permian mass extinction event initiated in the Olenekian and diversification continued until the Carnian. The most diverse and abundant Early Triassic gastropod faunas are from the Moenkopi Formation (Utah) and the Upper Werfen Formation (Europe, Alps), which contribute as much as 50% to the reported global ...

PERMIAN-TRIASSIC BOUNDARY AND EARLY TRIASSIC CONODONTS FROM THE SOUTHERN ALPS, ITALY

RIVISTA ITALIANA DI PALEONTOLOGIA E STRATIGRAFIA, 2020
The Bellerophon (Late Permian) and Werfen (Lower Triassic) Formations were investigated on the basis of conodonts. Fifteen sections were sampled from Carnic Alps and Dolomites area in the Southern Alps. Ten were productive. The Bellerophon Formation yielded a few specimens of Hindeodus typicalis, Ellisonia agordina and Ellisonia sp. In the ...

An early trend towards gigantism in Triassic sauropodomorph dinosaurs [PDF]

Nature Ecology & Evolution, 2018
Dinosaurs dominated the terrestrial ecosystems for more than 140 Myr during the Mesozoic era, and among them were sauropodomorphs, the largest land animals recorded in the history of life. Early sauropodomorphs were small bipeds, and it was long believed that acquisition of giant body size in this clade (over 10 tonnes) occurred during the Jurassic and

Biomineralization of primary carbonate cements: a new biosignature in the fossil record from the Anisian of Southern Italy

Lethaia, EarlyView., 2021
Biomineralization is a generic term used to indicate biological‐mediated mineral formation. In carbonate mineralization, nucleation of crystals can be: (1) controlled directly by the organisms, like in the skeletal formation of most metazoans; (2) induced by microbial communities, by indirect precipitation mediated by their metabolic activities; or (3)
