Shoreline and deglaciation chronology in southeast Norway

Boreas, Volume 55, Issue 1, Page 29-56, January 2026.
The postglacial relative sea level history is reconstructed in four areas of mid‐ and inner Oslofjorden in southeast Norway. The reconstructions are based on radiocarbon‐dated raised shoreline levels from 42 sites, mainly isolation basins, and limiting ages from four lakes above the marine limit.

Foraminifera Distribution Patterns within Sequence Stratigraphy (A Case Study: Blora Area and Surroundings/Low Latitude Area)

Journal of Mathematical and Fundamental Sciences, 2019
Sari. Analisis stratigrafi sikuen memerlukan data yang menyeluruh dari berbagai disiplin ilmu geologi, termasuk biostratigrafi. Secara hipotesis, biostratigrafi (foraminifera) dapat dijadikan alat untuk mengidentifikasi sikuen.

The Neoproterozoic Throssell Range Group, Western Australia: A Peri‐Marginal Continental Basin in Rodinia and Its Implications for the Centralian Superbasin

Basin Research, Volume 38, Issue 1, January–February 2026.
This study of recent exploration drillcore reveals two sequences separated by a disconformity. Basal alluvial fan to shallow marine lithofacies suggest reactivation of basement faults, and a distinct upwelling signature points to a flooded margin, controlled by differential subsidence of diverse Proterozoic lithosphere.

Localized and Transient Oxygenation of Shallow Oceans of Southwestern Laurentia at the Ediacaran–Cambrian Boundary

Geobiology, Volume 24, Issue 1, January/February 2026.
ABSTRACT The Ediacaran–Cambrian boundary, which precedes one of the most significant biotic diversification events in Earth's history, is associated with a global negative carbon isotope excursion termed the BAsal Cambrian carbon isotope Excursion (BACE).

Microbiostratigraphy of the Berriasian–Valanginian boundary in eastern Crimea: foraminifers, ostracods, organic-walled dinoflagellate cysts

Geologica Carpathica, 2017
Thorough study of foraminifers, ostracods and dinoflagellate remnants from the Zavodskaya Balka and Koklyuk sections helps to characterize the detailed biostratigraphic division of the Berriasian / Valanginian boundary sequence in the Feodosiya district ...

A >70‐Myr‐Long Geomagnetic Field Reversal Hyperactivity Across the Ediacaran‐Cambrian Transition

Geophysical Research Letters, Volume 52, Issue 23, 16 December 2025.
Abstract The long‐term variation of the geomagnetic field is a key constraint for unraveling the geodynamo processes and the evolution of Earth's deep interior. However, the geomagnetic reversal pattern during the Ediacaran–Cambrian transition remains elusive. Here we present an integrated magneto‐ and cyclo‐stratigraphic study of a ∼1.8‐Myr‐long, late

Almost billfish: convergent longirostry, micro‐dentition, and possible glandular sinuses in a large teleost fish from the Upper Cretaceous of Northern Italy

Journal of Anatomy, Volume 247, Issue 6, Page 1109-1130, December 2025.
A 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.

Stratigraphy of diagenesis: Limestone–dolomite cycles in a mid‐ramp setting, Miocene Arcadia Formation, South Florida, USA

The Depositional Record, Volume 11, Issue 5, Page 1433-1450, November 2025.
The data and interpretations of this study are used to test the proposal by Goldhammer et al. that a ‘stratigraphy of early diagenesis’ is operational in carbonate depositional systems. What this means is that distinct mineralogical and geochemical changes to rock and sediment occur associated with external controls, such as the rise and fall of sea ...

Zaplavnensky horizon - a new stratone in the Lower Triassic of the East European platform

Известия высших учебных заведений: Геология и разведка, 2016
A new horizon, called Zaplavnensky, is suggested on the base of verhnesukhorechenskaya subsuite of Buzulukskaya depression in the Lower Triassic of the East European platform.

The Cenomanian–Turonian boundary interval in the Western Canada Foreland Basin: Stratigraphy, geochemistry, geochronology and sea‐level changes recorded in expanded and condensed clastic successions

The Depositional Record, Volume 11, Issue 5, Page 1200-1258, November 2025.
Shallow‐marine mudstone of the Cretaceous Kaskapau Formation in the British Columbia foredeep preserves a 185 m thick record of OAE2. The organic carbon‐isotope and osmium‐isotope excursions can be correlated in detail with other Cenomanian–Turonian boundary sections around the world.
