The Swanscombe fossil at 90: revisiting its phylogeny, taxonomy, and place in human origins Le fossile de Swanscombe, 90 ans après : retour sur sa place phylogénique, taxonomique et dans les origines de l'humanité

Journal of the Royal Anthropological Institute, EarlyView.
The year 2025 marked the ninetieth since a fossil hominin occipital bone was discovered in Swanscombe, southeast England. In subsequent years, its parietal bones were found, producing what remains the oldest partial cranium from Britain today. In the earliest analyses, it was interpreted as a descendant of the infamous fraudulent fossil Piltdown Man ...

What lies in between: Levallois, discoid and intermediate methods

Journal of Lithic Studies, 2023
Lithic artefacts are usually associated with the different knapping methods used in their production. Flakes exhibit metric and technological features representative of the flaking method used to detach them.

Making Mining Licit: Gold, Commodification, and the Everyday Performance of Law in Colombia

American Anthropologist, EarlyView.
ABSTRACT Ethnographies of resource‐making have shown that the extraction of resource value from objects is premised on obviating the emplaced lifeworlds that surrounded objects before they traveled to consumer markets. Much of this literature looks at such supply‐chain disentanglement from the viewpoint of corporate and formal regulatory practices ...

Refitting the Context: A Reconsideration of Cultural Change among Early Homo sapiens at Fumane Cave through Blade Break Connections, Spatial Taphonomy, and Lithic Technology

Journal of Paleolithic Archaeology
High-resolution stratigraphic frameworks are crucial for unraveling the biocultural processes behind the dispersals of Homo sapiens across Europe. Detailed technological studies of lithic assemblages retrieved from multi-stratified sequences allow ...

Progressively Fenitised Schist and Carbonatitic Clasts From a Metasomatic Aureole Beneath the Alkalic Dunedin Volcano, Otago, New Zealand

New Zealand Journal of Geology and Geophysics, Volume 69, Issue 2, June 2026.
Clasts of albite‐porphyroblastic quartzofeldspathic schist, derived from the Otago Schist basement, occur within the Port Chalmers Breccia, a diatreme at the centre of the Dunedin stratovolcano, New Zealand. Schists have undergone varying degrees of replacement reactions (at temperatures of 300° to >500°C) producing hornfelses, with Ca‐ and K‐enriched ...

Formation and Deformation of a Short‐Lived and Immature Continental Back‐Arc Basin in Southeastern Tibet

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 4, April 2026.
Abstract Comprehension of the ophiolitic mélange plays a key role in the tectonic reconstruction of an ancient orogenic belt in terms of plate tectonics. The tectonic nature of the NNW‐trending southern Jinshajiang ophiolitic mélange is still controversial.

The lithic assemblages from the Palaeolithic survey research in the Megalopolis Basin, Greece

Journal of Lithic Studies
An intensive, target-oriented surface survey conducted in the Megalopolis basin during 2012-2013 led to the discovery of several Palaeolithic sites and findspots with lithics and faunal remains, including Marathousa-1, a Lower Palaeolithic open-air ...

Modeling the Transport and Dispersion of Volcanic Co‐PDC Ash Clouds Using NAME: An Evaluation of Source Geometry and Mass Eruption Rate

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 6, 28 March 2026.
Abstract Pyroclastic density currents (PDCs) are gravity currents that frequently form during explosive volcanic eruptions. These ground‐hugging density currents consist of high‐temperature mixtures of pyroclasts (e.g., ash, pumice), lithics, and gas.
