Old Fossils, New Information: Insights into Site Formation Processes of Two Pleistocene Cave Sequences in Zambia from Enamel Amino Acid Geochronology Open
Intra-crystalline protein degradation (IcPD) analysis was undertaken on 80 fossil tooth enamel samples from four taxonomic groups (rhinocerotid, suid, equid, bovid) excavated from two archaeological cave sites in Zambia (Twin Rivers and Mu…

Notes on Pleistocene and Recent non-marine Mollusca from Zambia Open
Pleistocene and Recent non-marine molluscan faunas from Zambia, and from South-Central Africa more generally, are relatively poorly understood. Many extant species have been reported only from single localities, often the type localities f…

Investigating the potential of African land snail shells (Gastropoda: Achatininae) for amino acid geochronology Open
Aragonitic calcium carbonate (CaCO3) terrestrial mollusc shells with complex shell microstructures, such as those in the African subfamily Achatininae, have the potential to be used to build amino acid geochronologies across the African co…

The genetic legacy of the expansion of Bantu-speaking peoples in Africa Open
With the largest genomic dataset to date of Bantu-speaking populations, including newly generated data of modern-day and ancient DNA from previously unsampled regions in Africa, we shed fresh light on the expansion of peoples speaking Bant…

Challenges of dating quartz OSL samples with saturated grains: Lessons from single-grain analyses of low dose-rate samples from Victoria Falls, Zambia Open
A suite of samples from an extensive aeolian sandscarp near Victoria Falls, Zambia was used to explore several different methods of calculating optically stimulated luminescence (OSL) ages that account for the effects of saturated quartz g…

Semiotics and the Origin of Language in the Lower Palaeolithic Open
This paper argues that the origins of language can be detected one million years ago, if not earlier, in the archaeological record of Homo erectus . This controversial claim is based on a broad theoretical and evidential foundation with la…

From <i>Chaîne Opératoire</i> to Observational Analysis: A Pilot Study of a New Methodology for Analysing Changes in Cognitive Task-Structuring Strategies Across Different Hominin Tool-Making Events Open
The chaîne opératoire (CO) approach is a well-established method for the analysis of tool creation, use and discard, and associated cognitive processes. Its effectiveness in respect of cognition, however, is occasionally challenged. We bri…

A Dynamical Analysis of the Suitability of Prehistoric Spheroids from the Cave of Hearths as Thrown Projectiles Open
Spheroids are ball-shaped stone objects found in African archaeological sites dating from 1.8 million years ago (Early Stone Age) to at least 70,000 years ago (Middle Stone Age). Spheroids are either fabricated or naturally shaped stones s…

Quaternary fossil fauna from the Luangwa Valley, Zambia Open
This paper describes a large collection of Quaternary fossil fauna from the Luangwa Rift Valley, Zambia. Stone Age artefacts have been recovered from stratified fluvial contexts, but no in situ fossil faunas have yet been recovered. We rep…

Excavations at Site C North, Kalambo Falls, Zambia: New Insights into the Mode 2/3 Transition in South-Central Africa Open
We report on the results of small-scale excavations at the archaeological site of Kalambo Falls, northern Zambia. The site has long been known for its stratified succession of Stone Age horizons, in particular those representing the late A…

New investigations at Kalambo Falls, Zambia: Luminescence chronology, site formation, and archaeological significance Open
Fluvial deposits can provide excellent archives of early hominin activity but may be complex to interpret, especially without extensive geochronology. The Stone Age site of Kalambo Falls, northern Zambia, has yielded a rich artefact record…
