The Unexpected Discovery of Paleocene? Coals in Outcrops Thought to Be Cambrian, Al Huqf, Oman

Journal of Petroleum Geology, EarlyView.
ABSTRACT Two brown organic deposits were encountered whilst investigating kaolinitic claystones thought to occur at the base of a Cambrian formation at outcrop. The age of these organic deposits is probably Paleocene from palynology. Organic petrography shows that they are subbituminous coals with some oil source potential.

High-resolution ecosystem changes pacing the millennial climate variability at the Middle to Upper Palaeolithic transition in NE-Italy

Scientific Reports, 2023
Observation of high-resolution terrestrial palaeoecological series can decipher relationships between past climatic transitions, their effects on ecosystems and wildfire cyclicity. Here we present a new radiocarbon dated record from Lake Fimon (NE-Italy)

Multi‐proxy sequence stratigraphy of a mixed carbonate–siliciclastic shelf across the Jurassic–Cretaceous transition

The Depositional Record, Volume 12, Issue 4, September 2026.
An integrated facies, MS and XRF‐based approach applied to the Tithonian–Berriasian Sidi Khalif Formation (central Tunisia) resolves five Tithonian and eight Berriasian third‐order sequences, showing how mixed carbonate–siliciclastic shelves record coupled eustatic, climatic and tectonic controls and providing a transferable template for similar mud ...

The Complete Chloroplast Genome Sequences of Salvia reflexa and Genome Comparison: Implications for Phylogeny and Plant Invasion

Ecology and Evolution, Volume 16, Issue 8, August 2026.
This study reports the complete chloroplast genome of Salvia reflexa and compares it with those of other invasive and non‐invasive Salvia species to explore genomic features associated with invasiveness. The chloroplast genome exhibits a typical quadripartite structure and shows high conservation within the genus, while several hypervariable regions ...

Pollen, women, war and other things: reflections on the history of palynology

Vegetation History and Archaeobotany, 2018
The development of palynology since its recognised launch in 1916 by Lennart von Post is examined in terms of its historiography, the biographies of pollen analysts and the role of those who have influenced the discipline.

Farming in the shadows of Rome: A multi‐proxy palaeoenvironmental record from Loch Clunie—Perthshire

Journal of Quaternary Science, Volume 41, Issue 6, Page 915-932, August 2026.
ABSTRACT Roman impacts on local society is a subject of international significance. Loch Clunie, Perthshire, lies only 5.4 km from Inchtuthil, the only Roman legionary fortress in Scotland, and contains two crannogs and a probable lakeside hillfort. Despite this proximity and the likelihood of local–Roman interaction, these sites remain unexcavated ...

Quantitative Palynology Informing Conservation Ecology in the Bohemian/Bavarian Forests of Central Europe

Frontiers in Plant Science, 2018
In 1927, the first pollen diagram was published from the Bohemian/Bavarian Forest region of Central Europe, providing one of the first qualitative views of the long-term vegetation development in the region. Since then significant methodological advances
