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 ...

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.

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.

The oldest acanthomorph fossil (Actinopterygii, Teleostei) from the Early Cretaceous of Gondwana (Morro do Chaves Formation, Sergipe–Alagoas Basin, NE Brazil)

Papers in Palaeontology, Volume 12, Issue 1, January/February 2026.
Abstract This paper presents the discovery of †Gondwanacanthus decollatus, a new genus and species of Early Cretaceous deep‐bodied fish from the late Barremian or early Aptian Morro do Chaves Formation in the Sergipe–Alagoas Basin, northeastern Brazil. It represents the first record of Acanthomorpha in Early Cretaceous Gondwana.

Drastic peatland regime shift and landscape disturbances connected to warm and cold climate events over the past centuries in subarctic Finland

Boreas, Volume 55, Issue 1, Page 85-97, January 2026.
Palaeoecological studies reporting long‐term development histories of subarctic fens—explicitly, orohemiarctic peatlands—are scarce, and overall, permafrost‐free peatlands located in the immediate vicinity of permafrost zones have received little attention in Fennoscandia. Here, we use a multiproxy approach to study the millennial‐scale dynamics of two

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 ...

Holocene Land‐Use and Climate Forcing of Ombrotrophic Peatland Dynamics in Northwest Estonia

Journal of Geophysical Research: Biogeosciences, Volume 130, Issue 12, December 2025.
Abstract We present a high‐resolution, multi‐proxy record from Mustjärve bog, northwest Estonia, covering the past ∼2,500 years. By integrating paleoecological, historical, and climate data, we evaluate how climate and land use shaped peatland hydrology, vegetation, and carbon dynamics.

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 ...

The White Stone Band of the Kimmeridge Clay Formation, an integrated high resolution approach to understanding environmental change

, 2004
The Kimmeridge Clay is a Jurassic mudrock succession that shows Milankovitch Band climatic cyclicity. A key issue is to determine how the subtle changes that define this cyclicity result from climatic change.

Water pathways and ancient lakes: Flowing towards new models to unravel the past

The Depositional Record, Volume 11, Issue 5, Page 1554-1562, November 2025.
Abstract Significant progress has been made in understanding lake basin evolution through climatic and tectonic changes using sedimentology, sequence stratigraphy, geochemistry, hydrology and watershed characteristics to interpret three main lake basin types: overfilled, balanced‐fill and underfilled, including fluvio‐lacustrine systems.
