PALEONTOLOGY AND EVOLUTIONARY LINEAGES OF THE DIAGNOSTIC BENTHIC FORAMINIFERAL GENUS ORTHOKARSTENIA [PDF]

open access: yesGeological Behavior, 2022
This work is focused on the members of the Late Cretaceous-Early Paleogene (K-Pg) diagnostic benthic foraminiferal genus Orthokarstenia which is regionally important in paleontology and stratigraphic correlations.

40 years of field work in the Triassic marine vertebrate sites [PDF]

open access: yesResearch & Knowledge, 2017
During the first 70 years of the XX century very few researches have concerned the marine Triassic fishes. They were prevalently related to the many scientific expeditions carried out in the first half of that century in localities situated along the ...

Paleocene orthophragminids from the Lakadong Limestone, Mawmluh Quarry section, Meghalaya (Shillong, NE India). Implications for the regional geology and paleobiogeography [PDF]

open access: yes, 2018
The late Paleocene orthophragminids, hitherto poorly known from the Himalayan foreland basins, are studied from the Lakadong Limestone in Meghalaya, northeastern India, in order to establish a systematic, biostratigraphic, and paleobiogeographical ...

Detrital Zircon Age Constraints on the Evolution of Paleo‐Tethys in NE Iran: Implications for Subduction and Collision Tectonics

open access: yesTectonics, 2021
The timings of the onset of oceanic spreading, subduction and collision are crucial in plate reconstructions, but not always straightforward to resolve.

Evaluation of the performance of a hydraulic barrier by the Null space Monte Carlo method

open access: yesAcque Sotterranee, 2019
A gasoline leak caused the contamination of a shallow alluvial aquifer in an urbanized area in Northern Italy. A rapid intervention was conceived to stop the spreading of contamination: a hydraulic barrier has been placed downstream of the source to ...

Quantifying Abundance and Mapping Distribution of Loggerhead Turtles in the Mediterranean Sea Using Aerial Surveys: Implications for Conservation

open access: yesDiversity, 2023
In the Mediterranean, incidental captures in fishing gear contribute to the high mortality of loggerhead turtles (Caretta caretta). Understanding the effects of bycatch is complex and requires robust knowledge of baseline population parameters such as ...

The Oligo–Miocene closure of the Tethys Ocean and evolution of the proto-Mediterranean Sea

open access: yesScientific Reports, 2020
The tectonically driven Cenozoic closure of the Tethys Ocean invoked a significant reorganization of oceanic circulation and climate patterns on a global scale. This process culminated between the Mid Oligocene and Late Miocene, although its exact timing

Climate warming, euxinia and carbon isotope perturbations during the Carnian (Triassic) Crisis in South China [PDF]

open access: yes, 2016
The Carnian Humid Episode (CHE), also known as the Carnian Pluvial Event, and associated biotic changes are major enigmas of the Mesozoic record in western Tethys.
