Proteromorphosis in Early Triassic Conodonts

, 2020
Herein 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.

Permian to early Triassic tectono-sedimentary evolution of the Mahu sag, Junggar Basin, western China: sedimentological implications of the transition from rifting to tectonic inversion

, 2021
The Permian to early Triassic terrestrial successions in the Mahu sag constrain the tectonic evolution of northwestern edge of the Junggar basin. This study analyzes the sequence stratigraphy of the Mahu sag in order to understand the interplay between ...

Conodont calcium isotopic evidence for multiple shelf acidification events during the Early Triassic

, 2021
The marine calcium (Ca) cycle is controlled by rates of continental weathering, seawater pH, and carbonate deposition on the seafloor and is linked to atmospheric CO2, climate change, and marine biotic evolution.

Integrated bio-chemostratigraphy of Lower and Middle Triassic marine successions at Spiti in the Indian Himalaya: Implications for the Early Triassic nutrient crisis

, 2021
In this paper we study the Lilang Super Group in the Spiti area, Indian Himalaya to understand environmental changes in the aftermath of the end-Permian mass extinction.

Paleoneurology of the Early Diversification of Triassic Archosauriforms and Pseudosuchians

2022
Paleoneurology 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 ...

Early Triassic Conchostracans (Crustacea: Branchiopoda) from the terrestrial Permian–Triassic boundary sections in the Moscow syncline [PDF]

Palaeogeography, Palaeoclimatology, Palaeoecology, 2015
© 2015 Elsevier B.V. The Permian-Triassic boundary marks the greatest mass extinction in Earth's history. In order to understand the real causes of this severe extinction event, multidisciplinary investigations around the globe are required.

Mercury enrichments provide evidence of Early Triassic volcanism following the end-Permian mass extinction

Earth-Science Reviews, 2019
Oceanic environments and biotas were in a state of near-continuous perturbation during the Early Triassic, the ~5-million-year interval following the latest Permian mass extinction (LPME), but the underlying cause(s) remain uncertain.

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

Early Triassic seawater sulfate drawdown

Geochimica et Cosmochimica Acta, 2014
Abstract 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 ...

Late Paleozoic to early Triassic multiple roll-back and oroclinal bending of the Mongolia collage in Central Asia

Earth-Science Reviews, 2017
The architecture and mechanics of an orogen can be understood in terms of a system of collages that are characterized by a complex assemblage of multiple components, but the fundamental paleogeographic framework and the tectonic relationships between the
