Erratic palynomorphs from some British tills [PDF]

Journal of Micropalaeontology, 1984
Abstract. The palynological investigation of tills (boulder clays) may provide considerable information about the direction of ice movement in lowland areas during the Pleistocene. Tills from Dyfed, Cheshire, Devon, Suffolk and Lincolnshire were subjected to palynological investigation.

Microbial mediation and climatic control on dolomite precipitation in a hypersaline lake: Insights from Salinas Lake, southern Iberia

The Depositional Record, Volume 12, Issue 1, February 2026.
The cyclical nature of aridity and humidity led to the alternating deposition of dolomite‐rich and calcite‐rich sediments. During arid phases, the lake hydrology and growth of microbial mats under evaporative and hypersaline environment favors the precipitation of dolomite.

Linking palaeo‐wildfire to depositional environmental and ecological dynamics of an Early–Middle Pennsylvanian fluvial‐tidal transition zone—Palynology and pyrolysis evidence

The Depositional Record, Volume 12, Issue 1, February 2026.
The Pennsylvanian landscape in the Forest City basin was characterised by low‐lying lycopod tree and fern swamp forests with persistently high groundwater tables and adjacent fluvial channel, floodplain and upland environments. The occurrence of abundant charcoal within a specific thin interval in the Cherokee Group indicates substantial wildfire ...

THE PERMIAN -TRIASSIC BOUNDARY, DEAD SEA, JORDAN: TRANSITIONAL ALLUVIAL TO MARINE DEPOSITIONAL SEQUENCES AND BIOSTRATIGRAPHY

Rivista Italiana di Paleontologia e Stratigrafia, 2016
The Permian to Triassic transition in Jordan is characterised by a sequence boundary underlain by red-bed, alluvial lithofacies deposited in a humid-tropical climate by low-sinuosity rivers, and overlain by shallow marine siliciclastics with thin ...

Palaeoclimate changes in the Afyon province, Sw-Turkey, during the Middle-Late Pleistocene: Signals from calcareous tufa pollen and stable isotope records [PDF]

, 2018
The calcareous tufas of Sarikavak located in the northern part of NE-SW trending Acigöl Graben in SW-Turkey are investigated in detail. For this aim, various analyses (stable isotopes, U/Th dating, palynology) have been carried out on samples obtained ...

An early Little Ice Age brackish water invasion along the south coast of the Caspian Sea (sediment of Langarud wetland) and its wider impacts on environment and people [PDF]

, 2015
Caspian Sea level has undergone significant changes through time with major impacts not only on the surrounding coasts, but also offshore. This study reports a brackish water invasion on the southern coast of the Caspian Sea constructed from a multi ...

Reconstructing Environmental and Microbial Ecosystem Changes Across the Permian–Triassic Mass Extinction at Lusitaniadalen, Svalbard

Paleoceanography and Paleoclimatology, Volume 41, Issue 2, February 2026.
Abstract The Permian–Triassic environmental crisis triggered fundamental changes in marine ecosystems, culminating in the most severe biodiversity crisis of the Phanerozoic. Yet, the environmental and geochemical conditions governing the crisis and ecosystem recovery remain debated.

The Nossa Senhora da Luz flora from the Early Cretaceous (early Aptian-late Albian) of Juncal in the western Portuguese Basin

Acta Palaeobotanica, 2018
A new fossil flora is described from the Early Cretaceous of the western Portuguese Basin, based on a combined palynological-mesofossil study. The fossil specimens were extracted from samples collected in the Nossa Senhora da Luz opencast clay pit ...

Intercalibration of Boreal and Tethyan timescales: the magneto-biostratigraphy of the Middle Triassic and the latest Early Triassic from Spitsbergen, Arctic Norway [PDF]

, 2008
An integrated bio-magnetostratigraphic study of the latest Early Triassic to the upper parts of the Middle Triassic, at Milne Edwardsfjellet in central Spitsbergen, Svalbard, allows a detailed correlation of Boreal and Tethyan biostratigraphies.

Unravelling the plot: Co‐producing visualisations of palaeo‐data to improve their utility in conservation practice

Ecological Solutions and Evidence, Volume 7, Issue 1, January–March 2026.
This study explores how typical palaeo‐data visualisations can hinder communication with conservation practitioners and other end users due to complexity, inaccessibility and unfamiliarity. Through a survey of palaeo‐researchers and presentation of two case studies, we highlight key barriers and demonstrate how collaboration with end users can improve ...
