Ceramic composition at Chalcolithic Shiqmim, northern Negev desert, Israel: investigating technology and provenance using thin section petrography, instrumental geochemistry and calcareous nannofossils [PDF]
, 2018 Technological innovations in ceramic production and other crafts are hallmarks of the Chalcolithic period (4500–3600 BCE) in the southern Levant, but details of manufacturing traditions have not been fully investigated using the range of analytical ...

Calcareous nannofossils from the Eocene North Atlantic Ocean (IODP Expedition 342 Sites U1403-1411) [PDF]
Journal of Nannoplankton Research, 2017 Integrated Ocean Drilling Program Expedition 342 (June-July 2012) cored nine sites and 18 holes (Sites U1403-U1411) on the J-Anomaly and the Southeast Newfoundland ridges in the NW Atlantic Ocean. These sites recovered sections ranging from Pleistocene

Chamber-by-Chamber Measurements of Planktonic Foraminiferal Mg, Sr, and Na to Ca Ratios With Femtosecond LA-ICP-MS. [PDF]
Rapid Commun Mass SpectromABSTRACT Rationale Distribution patterns of foraminifera are controlled by environmental parameters such as temperature, salinity, and nutrient concentrations in each water mass. Since trace elements to Ca ratios of marine microfossil calcite test of foraminifera record environmental and ecological habitat information, we used femtosecond (fs) LA‐ICP ...

Almost billfish: convergent longirostry, micro-dentition, and possible glandular sinuses in a large teleost fish from the Upper Cretaceous of Northern Italy. [PDF]
J AnatA fossil rostrum fragment of a large teleost fish from the Upper Cretaceous of Northern Italy reveals remarkable anatomical convergences with Cenozoic and Recent billfishes (marlins, swordfishes, and akin). The extinct group Plethodidae independently acquired a long snout, micro‐teeth, and oil‐gland sinuses well before the evolution of true billfishes.

Marcasite at the Permian‐Triassic Transition
Geophysical Monograph Series, Page 377-399., 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.

The role of calcareous nannofossils in building age models for Cenozoic marine sediments: a review
Rendiconti Lincei SCIENZE FISICHE E NATURALI, 2022 This review paper has been thought to emphasize the role of Biostratigraphy in Geosciences and, specifically, of calcareous nannofossils as dating tool. This group of calcareous plankton occurs in Mesozoic and Cenozoic carbonate-bearing marine sediments ...

Newsletters on stratigraphy, 2022 The Eocene–Oligocene transition (EOT; ca. 34–33.5 Ma) represents a key point in Cenozoic climatic evolution, marking the onset of a semipermanent ice sheet on Antarctica and a major step from a greenhouse to icehouse climate state (e.g. Coxall & Pearson,
