Abstract The End-Triassic Extinction event (ETE) has been recognized in numerous sections worldwide and it is usually marked by three negative carbon isotope excursions (NCIEs), named “precursor” (P-NCIE), “initial” (I-NCIE) and “main” (M-NCIE) negative carbon isotope excursions. These three NCIEs are significant characteristics of this time interval, and they are likely related to the emplacement of the Central Atlantic Magmatic Province (CAMP) that is considered the main trigger of the ETE… 
The Late Triassic Extinction at the Norian/Rhaetian boundary: Biotic evidence and geochemical signature
Abstract The latest Triassic was an interval of prolonged biotic extinction culminating in the end-Triassic Extinction (ETE). The ETE is now associated with a perturbation of the global carbon cycle
A review of the Late Triassic conodont conundrum: survival beyond biotic perturbations

Significant advance in the understanding of the Late Triassic evolution of conodonts and their final disappearance has been made recently. However, the relevant information is rather fragmented and
Sedimentary record of Upper Triassic impact in the Lagonegro Basin, southern Italy: Insights from highly siderophile elements and Re Os isotope stratigraphy across the Norian/Rhaetian boundary
Abstract The Norian and Rhaetian transition (Late Triassic) is characterized by a faunal turnover in major pelagic groups, such as radiolarians, conodonts, and ammonoids. Although catastrophic events
Sauropodomorph evolution across the Triassic–Jurassic boundary: body size, locomotion, and their influence on morphological disparity
Modifications in the locomotion and the successive increase in body mass seem to be the main attributes driving sauropodomorph morphospace distribution during the Late Triassic and earliest Jurassic.
Tracing volcanic emissions from the Central Atlantic Magmatic Province in the sedimentary record
Abstract The end-Triassic mass extinction (ETME) is thought to have been caused by voluminous, pulsed volcanic activity of the Central Atlantic Magmatic Province (CAMP). Over the last decades,
Evolutionary Process from Mockina bidentata to Parvigondolella andrusovi: Evidence from the Pizzo Mondello Section, Sicily, Italy
During their last phase of evolution, the pectiniform conodont elements manifested an evident trend of simplification and miniaturization. This phase started from the late Norian (Sevatian) in the


The end-Triassic mass extinction: A new correlation between extinction events and δ13C fluctuations from a Triassic-Jurassic peritidal succession in western Sicily
Abstract A new δ13Ccarb curve was obtained from an expanded peritidal succession in western Sicily and was used to investigate the relationships between isotopic signatures and biological events on
Triassic–Jurassic organic carbon isotope stratigraphy of key sections in the western Tethys realm (Austria)
The late Triassic period is recognized as one of the five major mass extinctions in the fossil record. All these important intervals in earth history are associated with excursions in C-isotope
Carbon-isotope stratigraphy and palynostratigraphy of the Triassic–Jurassic transition in the Tiefengraben section — Northern Calcareous Alps (Austria)
Abstract The end-Triassic is characterized by enhanced rates of biotic turnover in both the marine and terrestrial realms. Carbon-isotope anomalies have been reported worldwide that may indicate
A new Rhaetian δ13Corg record: Carbon cycle disturbances, volcanism, End-Triassic mass Extinction (ETE)
Abstract The links between large-scale volcanism, carbon cycle perturbations and the biotic crises at the End-Triassic Extinction event (ETE) are not well understood. The ETE seems to be marked by
A new correlation of Triassic–Jurassic boundary successions in NW Europe, Nevada and Peru, and the Central Atlantic Magmatic Province: A time-line for the end-Triassic mass extinction
Abstract Understanding the end-Triassic mass extinction event (201.36 Ma) requires a clear insight into the stratigraphy of boundary sections, which allows for long-distance correlations and correct
Carbon cycle dynamics following the end‐Triassic mass extinction: Constraints from paired δ13Ccarb and δ13Corg records
[1] Constraining the carbon isotopic changes associated with the end-Triassic mass extinction is key to understanding the causes of the extinction and dynamics of recovery from it. Yet the pattern
Global correlation of the radiolarian faunal change across the Triassic–Jurassic boundary
Precise comparison of the change in radiolarian faunas 3.5 m above a U-Pb zircon dated 199.6 ± 0.3 Ma tuff and approximately coincident with a negative δ 13 C anomaly in the Queen Charlotte Islands,
Integrated Upper Triassic Conodont and Radiolarian Biostratigraphies of the Panthalassa Ocean
Abstract. The Late Triassic conodont biostratigraphy of two pelagic chert sections (sections N and Q) in the Inuyama area, central Japan, was investigated to calibrate the Triassic radiolarian
New Upper Triassic Conodont Biozonation of the Tethyan Realm
Conodonts are biostratigraphically very important microfossils in the Upper Triassic, occurring in different marine habitats, from deep-ocean to shallow-shelf waters. Because of their great
Abstract Bivalves are the most common macrofauna present in marine sequences spanning the end-Triassic mass extinction and document the initial ecological response to the crisis. In the west-Tethyan
