Environmental dynamics and timing of the late Eemian interglacial to the Weichselian pleniglacial at Lichtenberg, Germany: implications for the Oerel and Glinde interstadials

Boreas, EarlyView.
The terrestrial sediment archives of northern Germany provide important insights into Late Pleistocene climate variability, but continuous and well‐dated records remain rare. In particular, the age and stratigraphic position of the Oerel and Glinde interstadials within the Early Weichselian to pleniglacial transition remain poorly constrained.

Evaluation of the Rb/Sr ratio as an indicator of chemical weathering: a case study from five sedimentary sections in Northeast China

Boreas, EarlyView.
Chemical weathering plays a pivotal role in the Earth's surface material cycle and global climate regulation. It not only facilitates the reconstruction of palaeoclimate characteristics but also provides essential insights into Earth's evolutionary history.

Stratigraphy and palaeoceanography of the Boreal Lower Cretaceous [PDF]

, 2012
Andauernde Diskussionen und gegensätzliche Interpretationen der paläoklimatischen und paläoozeanographischen Entwicklung der frühen Kreidezeit sind teilweise auf fehlende Daten der hohen Breiten zurückzuführen. Das Ziel dieser Arbeit ist ein besseres Verständnis der frühen Kreidezeit hinsichtlich der Stratigraphie, des Paläoklimas, der ...

Geochemical and granulometric fingerprints of 8200 years of westerly wind variability in inner‐fjord lake sediments from Svalbard

Boreas, EarlyView.
The Arctic is warming faster than any other region on Earth. As sea ice diminishes, the surface boundary conditions, such as roughness and air–sea coupling, change and open‐water fetch increases. This may enhance wind forcing on Arctic coasts. Lake sediments can record these changes through the deposition of wind‐blown grains and elements, offering ...

Unravelling the phylogeny of armadillos and their kin (Mammalia, Xenarthra, Cingulata) combining morphological, molecular, and stratigraphic data

Cladistics, EarlyView.
Abstract Cingulata, a major lineage of Xenarthra, comprises extinct and extant armoured placental mammals that diversified throughout the Cenozoic. Despite extensive study, phylogenetic hypotheses based on morphological and molecular data remain incongruent, and no total evidence analysis has been conducted. Here, we integrate the largest morphological
