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.

Magmatic records of subduction and closure of the Meso-Tethys Ocean in the northern-central Tibetan Plateau

open access: yesGSA Bulletin, 2023
The evolution of the Tethys Ocean has received much research attention; however, the timing and subduction mechanisms involved in the closure of the Bangong-Nujiang Meso-Tethys Ocean remain poorly constrained.

Biomineralization of primary carbonate cements: a new biosignature in the fossil record from the Anisian of Southern Italy

open access: yesLethaia, EarlyView., 2021
Biomineralization is a generic term used to indicate biological‐mediated mineral formation. In carbonate mineralization, nucleation of crystals can be: (1) controlled directly by the organisms, like in the skeletal formation of most metazoans; (2) induced by microbial communities, by indirect precipitation mediated by their metabolic activities; or (3)

Sedimentology and Diagenesis of the Early–Middle Eocene Carbonate Deposits of the Ceno-Tethys Ocean

open access: yesJournal of Marine Science and Engineering, 2022
An integrated study based on field observation, petrography, and scanning electron microscopy (SEM) on the Early–Middle Eocene carbonate rocks has been carried out, which were deposited in the Ceno-Tethys Ocean. The study area of the Yadgaar Section lies

Two ophiolite belts in the East Kunlun Orogenic Belt record evolution from the Proto-Tethys to Paleo-Tethys Oceans

open access: yesSoviet Economy, 2022
As relics of oceanic lithosphere, ophiolites exposed in the East Kunlun region are crucial for deciphering the evolution from the Proto-Tethys to the Paleo-Tethys.

PALEOBIOGEOGRAPHY OF SOME EGYPTIAN AND PAKISTANIAN BENTHIC FORAMINIFERAL SPECIES IN THE NORTHERN TETHYS [PDF]

open access: yesEarth Sciences Pakistan, 2021
Twenty-one benthic foraminiferal species were originally erected from the Southern Tethys, 13 species from Egypt, and 8 species from Pakistan. Some of these species were recorded from different localities in the Northern Tethys: France, Spain, Italy ...

A new clupeid fish from the upper Miocene of Greece: A possible Hilsa relative from the Mediterranean [PDF]

open access: yesActa Palaeontologica Polonica, 2021
Much remains to be learned about the past diversity and evolutionary history of the Clupeidae (herrings, shads and allies), owing to the frequently subtle differences between modern taxa and the moderate preservational quality of some fossils.

Mercury deposition in Western Tethys during the Carnian Pluvial Episode (Late Triassic)

open access: yesScientific Reports, 2021
The Late Triassic Carnian Pluvial Episode (CPE) was a time of biological turnover and environmental perturbations. Within the CPE interval, C-isotope and sedimentary records indicate multiple pulses of depleted carbon into the atmosphere–ocean system ...

PALEONTOLOGY, STRATIGRAPHY, PALEOENVIRONMENT AND PALEOGEOGRAPHY OF SIXTY-THREE CAMPANIAN-NEOGENE TETHYAN BENTHIC FORAMINIFERAL GENERA AND SPECIES OF ANAN B- SUBORDER LAGENINA [PDF]

open access: yesGeological Behavior, 2023
This study represents the second part of the erected assemblage of benthic foraminiferal genera and species of Anan, which related to the Suborder Lagenina, after the first part which belongs to the taxa of the Suborders Textulariina and Miliolina (Anan,

A new rhynchocephalian (Reptilia: Lepidosauria) from the Late Jurassic of Solnhofen (Germany) and the origin of the marine Pleurosauridae [PDF]

open access: yesRoyal Society Open Science, 2017
A new rhynchocephalian is described based on a recently discovered and well-preserved specimen from the Late Jurassic (Kimmeridgian) marine limestones of Solnhofen, Bavaria.
