EARLY TRIASSIC ORIGIN OF COCCOLITHOGENESIS
Rivista Italiana di Paleontologia e StratigrafiaCalcareous nannofossil investigations were conducted on Lower and Middle Triassic marine successions from South China. Coccoliths, nannoliths and calcispheres are relatively frequent and moderately preserved, showing an increase in diversity from the ...

REVIEW OF EARLY TRIASSIC THYLACOCEPHALA
Rivista Italiana di Paleontologia e Stratigrafia, 2021 Thylacocephala (Euarthropoda: Eucrustacea?) is a group of enigmatic fossil euarthropods, known from at least the Silurian to the Cretaceous. The Triassic is considered to be the period during which thylacocephalans were the most diversified with 17 ...

Early Triassic super-greenhouse climate driven by vegetation collapse. [PDF]
Nat Commun, 2022 The Permian–Triassic Mass Extinction (PTME), life’s most severe crisis1, has been attributed to intense global warming triggered by CO2 emissions from Large Igneous Province volcanism2–8. It remains unclear, however, why super-greenhouse conditions persisted for around five million years after the volcanic episode,

Early Triassic ichthyopterygian fossils from the Russian Far East. [PDF]
Sci Rep, 2022 AbstractIchthyopterygia is a major clade of reptiles that colonized the ocean after the end-Permian mass extinction, with the oldest fossil records found in early Spathian substage (late Olenekian, late Early Triassic) strata in the western USA. Here, we describe reptilian remains found in situ in the early Spathian Neocolumbites insignis ammonoid zone

Early Triassic marine biotic recovery: the predators' perspective. [PDF]
PLoS One, 2014 Examining the geological past of our planet allows us to study periods of severe climatic and biological crises and recoveries, biotic and abiotic ecosystem fluctuations, and faunal and floral turnovers through time. Furthermore, the recovery dynamics of large predators provide a key for evaluation of the pattern and tempo of ecosystem recovery because

Prolonged Late Permian-Early Triassic hyperthermal: failure of climate regulation? [PDF]
Philos Trans A Math Phys Eng Sci, 2018 The extreme warmth associated with the mass extinction at the Permian–Triassic boundary was likely produced by a rapid build-up of carbon dioxide in the atmosphere from the eruption and emplacement of the Siberian Traps. In comparison to another hyperthermal event, the Palaeocene–Eocene Thermal Maximum, the Permian–Triassic event, while ...

Provenance and tectonic settings of late Triassic–Jurassic deposits in the Southwestern Yangtze block: evidence from the geochemistry, SW China [PDF]
Scientific ReportsDuring the Late Triassic to Jurassic, the western Yangtze Block transitioned from marine carbonate deposits to terrestrial detrital deposits. There are different views on the orogen evolution of the western margin of the Yangtze Block, such as whether ...

A Hiatus Obscures the Early Evolution of Modern Lineages of Bony Fishes
Frontiers in Earth Science, 2021 About half of all vertebrate species today are ray-finned fishes (Actinopterygii), and nearly all of them belong to the Neopterygii (modern ray-fins). The oldest unequivocal neopterygian fossils are known from the Early Triassic.
