The Triassic [PDF]

Current Biology, 2016
The Triassic, lasting from 252 to 201 million years (Myr) ago, was crucial in the origin of modern ecosystems. It is the seventh of the 11 geological systems or periods into which the Phanerozoic, the fossiliferous last 540 million years, of Earth history is divided.

An enormous sulfur isotope excursion indicates marine anoxia during the end-Triassic mass extinction

Science Advances, 2020
Low ocean sulfate levels at the end-Triassic mass extinction linked to rapid development of marine anoxia. The role of ocean anoxia as a cause of the end-Triassic marine mass extinction is widely debated.

Spondarthritis in the Triassic

PLoS ONE, 2010
The evidence of several forms of arthritis has been well documented in the fossil record. However, for pre-Cenozoic vertebrates, especially regarding reptiles, this record is rather scarce. In this work we present a case report of spondarthritis found in a vertebral series that belonged to a carnivorous archosaurian reptile from the Lower Triassic ...

Flat latitudinal diversity gradient caused by the Permian–Triassic mass extinction

Proceedings of the National Academy of Sciences of the United States of America, 2020
Significance The deep-time dynamics of the latitudinal diversity gradient (LDG), especially through dramatic events like mass extinctions, can provide invaluable insights into the biotic responses to global changes, yet they remain largely underexplored.

Polish Palaeobotany: 750 Million Years of Plant History as Revealed in a Century of Studies. Mesozoic Terrestrial Palynology and Flora Reconstruction

Acta Societatis Botanicorum Poloniae, 2022
Palynological studies of the Mesozoic era in Poland began in the 1950s. These investigations developed in many directions, including stratigraphy, systematics of spores and pollen grains and their botanical affinities, as well as paleoecological and ...
