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.

Voltziopsis, a southern conifer of lower Triassic age [PDF]

open access: yesPapers and proceedings of the Royal Society of Tasmania, 1967
Shoots ascribed to Voltziopsis africana Seward are described, with cuticular detail. These compare very closely with the shoot system, with an attached seed cone, caned V. wolganensis sp. nov., which is associated with pollen of the Strotersporites Wilson sort.

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 ...

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,

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
