Columnanidus calitzdorpensis ichnogen. ichnosp. nov: A new Middle Pleistocene subterranean termite trace fossil from South Africa

Journal of Quaternary Science, EarlyView.
ABSTRACT Termites are landscape geo‐engineers whose nesting activities substantially modify the physical and chemical properties of soils. Fossilised termite nests commonly constitute the only identifiable evidence of ancient termite activity and represent valuable trace fossil archives for reconstructing past environments.

Identification and correlation of the Aso‐3 tephra in the Omaezaki area, central Japan: A valuable key stratum for the MIS 6/5 transition period

Journal of Quaternary Science, EarlyView.
ABSTRACT The Aso‐3 tephra is one of the most significant widespread marker layers from the Middle to Late Pleistocene, generated by a large caldera‐forming eruption at the Aso volcano in Kyushu, southwestern Japan. Despite its importance, a distal co‐ignimbrite ash correlative has yet to be clearly identified, primarily because although volcanic glass ...

Geochronological reconstruction of the Lateglacial deglaciation in the Arve Valley (Northern French Alps)

Journal of Quaternary Science, EarlyView.
ABSTRACT The timing and spatial patterns of glaciers retreat in the Northern French Alps during the Lateglacial (19.0–11.7 ka) remain debated, reflecting discrepancies among available chronological data sets. The complex interactions between major glaciers, such as the Rhône and Arve glaciers to the north and the Isère glacier to the south, represent a

Raman Line Scan Analyses and a New Hypothesis for the Formation of Anatase‐Hosting Microbialites: Study of the Stromatolites From Saint‐Jean‐de‐la‐Rivière, Cotentin, France

Journal of Raman Spectroscopy, EarlyView.
Micrometer analysis of millimeter lines of Raman spectra concludes in the association of anatase and graphitized organic matter (graphogen). The photosynthetic microorganisms at the origin of the microbialites produce O2, which is transformed by TiO2 into reactive species that, in turn, decompose the organic matter of the microorganisms. ABSTRACT Raman

Exploitation of Rabbits at the Dawn of the Holocene: Evidence From the Font Voltada Site (Northeastern Iberia) Using Comparative Neotaphonomic Models

International Journal of Osteoarchaeology, EarlyView.
ABSTRACT During the transition from the Pleistocene to the Holocene, hunter‐gatherer societies in the northeastern Iberian Peninsula increased the number of settlements and broadened their subsistence strategies. This period is marked by the appearance of terrestrial snail accumulations attributable to human harvesting, the expansion of specialized ...

A GIS‐Based Approach to Modeling Carnivore Activity in the Pleistocene Site of Cova del Rinoceront (Iberian Peninsula)

International Journal of Osteoarchaeology, EarlyView.
ABSTRACT A significant methodological difficulty in the interpretation of Pleistocene zooarchaeological assemblages is the identification of taphonomic agents that modify and break bones. Carnivores, in particular, have been a main focus, as competition with carnivores may have affected carcass acquisition opportunities for humans in the past.
