Edge Sharpness Does Not Vary Between Palaeolithic Flake Technologies, With the Possible Exception of Levallois Débitage

Archaeometry, EarlyView.
ABSTRACT Investigating why hominins adopted particular flake technologies during the Mid‐to‐Late Pleistocene is essential to understanding patterns of lithic innovation. This period witnessed the emergence of Levallois technologies (~350–250 ka) and later blades, each “replacing” earlier forms.

Map Room Conversations: Mapping Objects

Area, EarlyView.
Short Abstract This article presents reflections on a ‘Map Room Conversation’ session entitled ‘Mapping Objects’ at the RGS International Conference, 2024. The session considered the three dimensional aspects of map‐making, both the objects and methods involved with producing maps, and the construction of maps in three dimensions in the form of relief ...

Morphometric and Paleobiological Insights Into Pleistocene Sicilian Wolf Populations

Acta Zoologica, EarlyView.
ABSTRACT The Pleistocene wolves (Canis lupus) from Sicily represent one of the few known insular populations of this species from that time period. Despite their potential relevance for understanding carnivore adaptations in insular contexts, no dedicated study has previously investigated their morphology and evolutionary significance.

Unravelling the evolution of the Frébouge polygenetic cone in Val Ferret (Mont Blanc Massif)

Boreas, EarlyView.
Proglacial settings in the Alps are typically polygenetic, often characterized by a complex and discontinuous interplay between glacial, fluvial and gravitational processes. These processes yield high volumes of sediments, which usually exceed their transportation capacity.

Middle to Late Pleistocene landscape evolution and glacial dynamics in the Eastern Alps: the Gröbminger Mitterberg record, Austria

Boreas, EarlyView.
Glacial erosion during the Last Glacial Maximum (LGM) has removed much evidence of earlier glaciations and interglacials in the European Alps. At Gröbminger Mitterberg (GM), beneath a blanket of LGM till, a distinctive sediment archive preserves deposits predating the LGM.
