Paleoneurology of the Early Diversification of Triassic Archosauriforms and Pseudosuchians
2022Paleoneurology is a branch of paleontology that is dedicated to the study of the anatomy and evolution of the nervous system of extinct animals. You are reading the introduction to this book about paleoneurology because you are a descendent of a long line of primate ancestors that had evolved progressively larger brains, and that were eventually able ...

Dienerian (Early Triassic) ammonoids and the Early Triassic biotic recovery: a review
2018It has been estimated that about 90% of all marine species disappeared during the end-Permian mass extinction (Raup & Sepkoski 1982). It is the biggest known biodiversity crisis in the history of Phanerozoic life, and it led to the replacement of typical Palaeozoic faunas by typical modern communities (Sepkoski 1984). The recovery which followed in

Proteromorphosis in Early Triassic Conodonts
2020Herein we emphasise how environment, palaeoecology and palaeobiogeography play key roles in the evolution of organisms. Nineteenth-century ammonoid biochronology led to the definition of the Mesozoic stages. Their beginning and end are bound by the biggest mass extinctions of Earth history.

Early Triassic seawater sulfate drawdown
Geochimica et Cosmochimica Acta, 2014Abstract The marine sulfur cycle is intimately linked to global carbon fluxes, atmospheric composition, and climate, yet relatively little is known about how it responded to the end-Permian biocrisis, the largest mass extinction of the Phanerozoic. Here, we analyze carbonate-associated-sulfate (CAS) from three Permo–Triassic sections in South China ...

Early ornithischian dinosaurs: the Triassic record
Historical Biology, 2007Ornithischian dinosaurs are one of the most taxonomically diverse dinosaur clades during the Mesozoic, yet their origin and early diversification remain virtually unknown.

Recurrent Early Triassic ocean anoxia
Geology, 2012The Early Triassic record, from the Smithian stratotype, shows that the organic carbon isotope record from northwest Pangea closely corresponds to major fluctuations in the inorganic carbon records from the Tethys, indicating truly global perturbations of the carbon cycle occurred during this time. Geochemical proxies for anoxia are strongly correlated

Late Permian to Early Triassic magnetostratigraphy
Earth and Planetary Science Letters, 1991A Late Permian to Early Triassic magnetostratigraphic reference section is presented. The Lower Triassic part is based on results from marine limestone sections in South China published earlier [1,2]. Reliable new Permian data are added here which have been collected in the Nammal gorge (Salt Range, Northwest Pakistan) where marine sediments have been ...

Early Triassic tetrapod faunas of southeastern Gondwana
Alcheringa: An Australasian Journal of Palaeontology, 1986A modified version of the Simpson index is used to assess similarities between the Early Triassic tetrapod faunas of Australia, Antarctica, India and South Africa. This index takes into account the relative abundances of taxa, and not merely their presence or absence.

Gastropod evidence against the Early Triassic Lilliput effect
Geology, 2010Size reduction in the aftermath of the Permian-Triassic mass extinction event has repeatedly been described for various marine organisms, including gastropods (the Lilliput effect). A Smithian gastropod assemblage from Utah, USA, reveals numerous large-sized specimens of different genera as high as 70 mm, the largest ever reported from the Early ...
