Three-dimensional geological modeling supports a revised Burdigalian chronostratigraphy in the North Alpine Foreland Basin [PDF]

open access: yes, 2019
Precise age data are a basic prerequisite for the correlation of a sedimentary succession with the Global Time Scale, which in turn allows one to place its biotic and other data in a global context.

THE RECORD OF THE TYPOTHERE PACHYRUKHOS (MAMMALIA, NOTOUNGULATA) AND THE CHINCHILLID PROLAGOSTOMUS (MAMMALIA, RODENTIA) IN THE SANTA CRUZ FORMATION (EARLY–MIDDLE MIOCENE) SOUTH TO THE RÍO COYLE, PATAGONIA, ARGENTINA

open access: yesPublicación Electrónica de la Asociación Paleontológica Argentina, 2021
The continental early–middle Miocene Santa Cruz Formation (SCF) from Patagonia is one of the most important stratigraphic units of southern South America in terms of the terrestrial Neogene record.

Fossil bears break free from inhibitory cascade constraints at least twice (Ursus minimus and Ursus deningeri) caused by dietary adaptations

open access: yesBoreas, Volume 55, Issue 2, Page 503-516, April 2026.
Bears deviate from the inhibitory cascade model (ICM) during molar size evolution, with two significant deviations linked to changes in diet: Ursus minimus and Ursus deningeri. Many bears exhibit a ‘partial ICM’, highlighting the relationship between relative molar size, dietary adaptations and dental development across different species.

Multidisciplinary approach to revisit the state of activity of a deep‐seated gravitational slope deformation in the frame of the Quaternary geomorphological evolution of the Central Apennines (Italy)

open access: yesEarth Surface Processes and Landforms, Volume 51, Issue 3, March 2026.
Abstract Evaluating the state of activity of Deep‐Seated Gravitational Slope Deformation (DSGSD) is a challenge that requires multidisciplinary analytical approaches. This research focuses on the slope‐scale gravitational process, framing the role of the Quaternary morphodynamics of a river valley where multiple DSGSDs coexist, to reconstruct the ...

An Early Miocene bumble bee from northern Bohemia (Hymenoptera, Apidae)

open access: yesZooKeys, 2017
A new species of fossil bumble bee (Apinae: Bombini) is described and figured from Early Miocene (Burdigalian) deposits of the Most Basin at the Bílina Mine, Czech Republic. Bombus trophonius sp. n., is placed within the subgenus Cullumanobombus Vogt and

Tectonostratigraphic Evolution of the Guyana Basin: Implications for Sediment Routing and Slope Stability

open access: yesBasin Research, Volume 38, Issue 2, March–April 2026.
Seismic profile across the Guyana Basin showing the main tectonostratigraphic units and an order‐of‐magnitude increase in sedimentation rates since the Middle Miocene corresponding with the onset of sedimentation dominated by mass transport deposits. ABSTRACT The Guyana Basin developed in an evolving tectonic setting, but a lack of subsurface data has ...

Two distinct decadal and centennial cyclicities forced marine upwelling intensity and precipitation during the late Early Miocene in central Europe [PDF]

open access: yesClimate of the Past, 2015
Within a 5.5 m thick succession of Upper Burdigalian (Karpatian) sediments in the North Alpine Foreland Basin (NAFB; Austria), dated to CNP-zone NN4, a high-resolution section was logged continuously.

The First Complete Chloroplast Genome of Lycium shawii: Genomic Architecture, Molecular Phylogenetics and Evolutionary Insights

open access: yesEcology and Evolution, Volume 16, Issue 1, January 2026.
The study presents the first complete chloroplast genome of Lycium shawii (PQ824997.1) spanning 155,936 bp and contains 128 genes (84 protein‐coding genes, 36 tRNAs, and eight rRNAs). Nucleotide diversity analysis highlighted atpI, rbcL, and accD as hypervariable loci suitable for DNA barcoding. Molecular dating analysis revealed that L.

From Compression to Extension in the Eastern Pyrenees: New Insights From Low‐Temperature Thermochronology

open access: yesTectonics, Volume 45, Issue 1, January 2026.
Abstract The tectonic evolution of the Eastern Pyrenees from the orogenic mountain building to the post‐orogenic dismantling is still debated. Since the Oligocene, the Gulf of Lion rifting in the Western Mediterranean superimposed crustal extension in this eastern part of the Pyrenean belt, while compressional tectonics persisted in the Central ...
