Large Igneous Province Record Through Time and Implications for Secular Environmental Changes and Geological Time‐Scale Boundaries

open access: yesGeophysical Monograph Series, Page 1-26., 2021

Exploring the links between Large Igneous Provinces and dramatic environmental impact

An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

A new Early Triassic crinoid from Nevada questions the origin and palaeobiogeographical history of dadocrinids [PDF]

open access: yesActa Palaeontologica Polonica, 2023
Knowledge of the early evolution of post-Palaeozoic crinoids mainly relies on the well-preserved and abundant material sampled in Triassic Konservat-Lagerstätten such as those from the Anisian Muschelkalk (Middle Triassic) of the Germanic Basin.

A new archosauriform (Reptilia: Diapsida) from the Manda beds (Middle Triassic) of southwestern Tanzania. [PDF]

open access: yesPLoS ONE, 2013
BackgroundArchosauria and their closest relatives, the non-archosaurian archosauriforms, diversified in the Early and Middle Triassic, soon after the end-Permian extinction. This diversification is poorly documented in most Lower and Middle Triassic rock

New insights on the early Mesozoic evolution of multiple tectonic regimes in the northeastern North China Craton from the detrital zircon provenance of sedimentary strata [PDF]

open access: yesSolid Earth, 2018
To investigate the timing of deposition and provenance of early Mesozoic strata in the northeastern North China Craton (NCC) and to understand the early Mesozoic paleotectonic evolution of the region, we combine stratigraphy, U–Pb zircon geochronology,

REVIEW OF EARLY TRIASSIC THYLACOCEPHALA

open access: yesRivista 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 ...

The timing of the initial collision between the South and North China blocks constraining from the sediments in the eastern Sichuan Basin

open access: yesScientific Reports, 2023
In this study, detrital zircon U–Pb geochronology, trace element and Hf isotopic compositional data from the Early-Middle Triassic clastic rocks in the eastern Sichuan Basin were obtained to distinguish the sediment provenance and constrain the timing of

The anatomy and phylogenetic position of the erythrosuchid archosauriform Guchengosuchus shiguaiensis from the earliest Middle Triassic of China [PDF]

open access: yesPeerJ, 2019
Erythrosuchidae is a clade of early archosauriform reptiles, which were apex predators in many late Early and Middle Triassic ecosystems, following the Permo-Triassic mass extinction.

Cambrian-Eocene pre-rift, pulsed rift, passive margin and emplacement processes along the northern margin of the Southern Neotethys: Evidence from the Antalya Complex in the Alanya Window (S Turkey)

open access: yesJournal of Asian Earth Sciences: X, 2020
Sedimentary rocks in the Alanya Window document pulsed Permian-Triassic rifting in a proximal basin setting, adjacent to the Tauride continental unit (Geyik Dağ).

Synopsis of the Triassic reptiles from Germany [PDF]

open access: yesFossil Record
Triassic strata in the portion of the Central European Basin (CEB) that cover parts of conterminous Germany have yielded a long if discontinuous record of continental tetrapods spanning this period.
