Abstract The latest Triassic was characterised by protracted biotic extinctions concluding in the End-Triassic Extinction (~ 200 Ma) and a global carbon cycle perturbation. onset of declining diversity is closely related to reducing conditions that spread globally from upper Sevatian (uppermost Norian) across Norian-Rhaetian boundary, likely triggered unusually high volcanic activity. We correlate significant organic perturbations an increase CO 2 ocean–atmosphere system, outgassed...
It is generally accepted that conodonts went extinct at the end of Triassic, but younger conodont fossils have been reported, and it becoming clear extinction occurred asynchronously across different regions. Although some reports post-Triassic disproven, Lower Jurassic found in Buda area Hungary Inuyama Japan. Here, we report discovery more Misikella posthernsteini above first occurrence typical radiolarian Pantanellium tanuens e, which not know from Kastuyama section, area, reaffirming...
Two significant stratigraphical microfossils, conodonts and radiolarians, are usually used for the Upper Triassic chronostratigraphy. The Baoshan Block was located in eastern Tethys during Late where biostratigraphical data of still poorly known. We collected new samples from Hongyan section (HY) study. This 24-m-thick Dabaozi Village, City, is mainly composed thin-layered limestones, sandstone siltstone. conodont fauna referred to Sevatian 1 (late Norian), which species Mockina englandi,...
The Norian "chaotic carbon episode" stands out as a compelling cycle perturbation event within the Late Triassic period. This episode has been documented in marine stratigraphic sections across North America, Italy, Japan, and China. However, limited chronostratigraphy available eastern Tethys inhibited identification of this broad area, thus possible global response to perturbation. To address issue, we analyzed conodonts carbon-isotope Sanhedong (SHD) section Simao terrane, Southwest...
Abstract Microfossils are important components of sedimentary rocks used for palaeontological, biostratigraphic, palaeoenvironmental and palaeoclimatic investigations. They usually extracted from using an acid solution, which might vary depending on the embedding rock lithology. Here we propose a new method common NaOH (sodium hydroxide; soda) to digest cherts (micro‐ cryptocrystalline quartz) instead standard technique based HF (hydrofluoric acid). This allows collection undamaged specimens...
Triassic was a critical period for significant increase in the generic diversity of radiolarians after disappearance more than 80% radiolarian genera during Permian-Triassic mass extinction. In particular, Upper fauna is very rich and documented from several world regions, such as North America, Western Europe, Mediterranean area, Japan, Philippines, Timor, Far East Russia. Moreover, upper Carnian-lower Norian interval marked by radiation Carnian Pluvial Episode, which short time...
Norian time interval is a crucial period in Earth’s evolutionary history, characterized by several organic carbon-isotope perturbations the carbon cycle that are closely related to global environmental change and biotic turnover (Zaffani et al., 2017). Among them, “chaotic episode” has been recently reported globally North America, Italy, Japan, from shallow pelagic environments (Whiteside Ward, 2011; Zaffani 2017; Jin 2022; Sato 2023). However, mechanisms...
The Triassic was a critical period for significant increase in the generic diversity of radiolarians after disappearance >80% radiolarian genera during Permian-Triassic mass extinction. In particular, Upper fauna is rich and has been documented several world regions, such as North America, Western Europe, Mediterranean area, Japan, Philippines, Timor, Far East Russia. this study, well-preserved high-diversity from continuous pelagic-hemipelagic section deposited western Tethys (Sicily,...
