The Osmium Isotope Signature of Phanerozoic Large Igneous Provinces

open access: yesGeophysical Monograph Series, Page 229-246., 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.

Sedimentary characteristics and sedimentary model of the Upper Permian-Lower Triassic shallow braided river delta in the hinterland of the Junggar Basin

open access: yesShiyou shiyan dizhi, 2023
The lower play of the Junggar Basin has huge oil and gas potential, which is the most important strategic succession field for oil and gas exploration. Large-scale delta sand bodies are developed in Permian and Triassic in the four sags in the hinterland,

The westernmost occurrence of Gnathorhiza in the Triassic, with a discussion of the stratigraphic and palaeogeographic distribution of the genus [PDF]

open access: yesFossil Record, 2016
The paper refines the taxonomic assignment of the only representative of the dipnoan genus Gnathorhiza from the Lower Triassic of Poland. It is assigned here to Gnathorhiza otschevi on the basis of morphological and biometrical similarity with the tooth ...

Lower Triassic conodont stratigraphy

open access: yesGeologica Balcanica, 1995
A conodont stratigraphic subdivision of the Lower Triassic is made, and considerations about the Permian/Triassic boundary are developed. Data received during the last few years are generalized with emphasis laid on results obtained on conodonts found by the authors in their samples from the Himalayas and different parts of Europe.

Plant remains from the Polish Triassic. Present knowledge and future prospects

open access: yesActa Palaeobotanica, 2014
The Triassic plant macrofossils of Poland are very poorly known. There are few Triassic rock exposures here, they contain very few plant specimens, there is little scientific interest in the subject, and the rare plant remains found in drill cores are of

A reappraisal of the Middle Triassic chirotheriid Chirotherium ibericus Navás, 1906 (Iberian Range NE Spain), with comments on the Triassic tetrapod track biochronology of the Iberian Peninsula [PDF]

open access: yesPeerJ, 2015
Triassic vertebrate tracks are known from the beginning of the 19th century and have a worldwide distribution. Several Triassic track ichnoassemblages and ichnotaxa have a restricted stratigraphic range and are useful in biochronology and biostratigraphy.

Taphonomy of the reference Middle Permian – Early Triassic tetrapod localities of the East European Platform. I. Perevolotsoye locality (Tupilakosaurus fauna)

open access: yesУчёные записки Казанского университета: Серия Естественные науки, 2020
The results of a taphonomic study of the Perevolotskoye locality (Orenburg region), a reference for the Early Triassic Tupilakosaurus fauna of southern areas of Eastern Europe, were presented. Based on the ratio of paired elements (hypo- and pleurocentra)

Characteristics and Research Direction of Triassic in the South Yellow Sea Basin, China

open access: yesGeofluids, 2022
To advance oil and gas exploration in the South Yellow Sea Basin, characteristics of Triassic, including its correlation with regional strata, distribution, lithology characteristics, and karst development characteristics, are studied by geological ...

On the Distribution of Lower Triassic Faunas [PDF]

open access: yesThe Journal of Geology, 1912
No formation has added more in recent years to our knowledge of ancient faunal geography than the Lower Triassic. In this epoch we now know three distinct and widely distributed interregional faunal zones, which are truly bench-marks in correlation. These are in sequence upward: (i) the Meekoceras zone; (2) the Tirolites zone; (3) the Columbites zone ...

On the Presence of a Pustulated Temnospondyl in the Lower Triassic of Southern Brazil [PDF]

open access: yesActa Palaeontologica Polonica, 2009
The fossil record of temnospondyls in South America has been greatly expanded in the last 10 years, increasing their overall significance. They occur in Argentina, Brazil, and Uruguay, and range from the Guadalupian to the Late Triassic. The Early Triassic temnospondyl record in southern Brazil is mainly composed of fragmentary specimens, usually repre−
