Fire use during the last glacial maximum: evidence from the epigravettian at ko...
Murphree, William; Ferro‐Vázquez, Cruz; Kulakovska, Larissa; Usyk, Vitalii I.; Kononenko, Olesia; Bosch, Marjolein D.; Haesaerts, Paul; Damblon, FreddyThe Last Glacial maximum (LGM), spanning from 26.5 to 19 thousand years before present (ka bp), is a period of extreme climatic degradation associated with reduced biomass production and resource stress throughout Eurasia. Arguably, one of the most fundamental tools for human survival during this cold and arid period was the ability to create, maintain and use fire. While fire is widely considered a ubiquitous ...
Revisiting the thermal alteration of buried bone
Gallo, Giulia; Aldeias, Vera; Stahlschmidt, MareikeThe impacts of heat exposure directly on bone material are widely acknowledged, yet a comprehensive understanding regarding the degree of thermal alteration experienced by bone buried beneath a combustion feature or fire event remains poorly described. Such potential incidental burning below a surface fire presents challenges for distinguishing between the intentional remains of fire use behaviors from haphazar...
New methods on the block: taxonomic identification of archaeological bones in r...
Fagernäs, Zandra; Troché, Gaudry; Goldberg, Paul; Goldberg, Paul; Hublin, Jean-Jacques; McPherron, Shannon P; Murphree, William; Olsen, Jesper VThe integration of biomolecular studies of past organisms with geoarchaeological studies can significantly improve our understanding of the relative chronology and context of archaeologically (in)visible behaviors. However, the complexity and sedimentological heterogeneity of archaeological deposits at a microscopic scale is often not taken into consideration in biomolecular studies. Here, we investigate the pr...
Sediment DNA can revolutionize archaeology—if it is used the right way
Aldeias, Vera; Stahlschmidt, Mareike C.The possibility of fingerprinting ancient organisms using the DNA they leave behind is a revolution in our understanding of the past. Paleogenetic studies are rewriting our knowledge on ancient hominin genomes, hominin dispersals, interbreeding events, and ancient DNA is also a key tool in biodiversity monitoring efforts. Of particular interest: We can now retrieve DNA directly from sediments and soils (sedaDNA...
The first Miocene fossils from coastal woodlands in the southern East African Rift
Bobe, René; Aldeias, Vera; Alemseged, Zeresenay; Anemone, Robert L.; Archer, Will; Aumaître, Georges; Bamford, Marion K.; Biro, Dora; Bourlès, Didier L.The Miocene was a key time in the evolution of African ecosystems witnessing the origin of the African apes and the isolation of eastern coastal forests through an expanding arid corridor. Until recently, however, Miocene sites from the southeastern regions of the continent were unknown. Here, we report the first Miocene fossil teeth from the shoulders of the Urema Rift in Gorongosa National Park, Mozambique. W...

Site formation histories and context of human occupations at the paleolithic si...
Aldeias, Vera; Sandgathe, Dennis; McPherron, Shannon; Bruxelles, Bibiana; Turq, Alain; Goldberg, PaulThe Paleolithic site of La Ferrassie (Dordogne, France) has contributed significantly to the understanding of Middle and Upper Paleolithic technocomplexes, as well as Neanderthal skeletal morphology. Excavations at the site have spanned more than a century and uncovered rich archaeological assemblages associated with the Mousterian, Chatelperronian, Aurignacian and Gravettian technocomplexes. Renewed excavation...
Late acheulean occupations at Montagu Cave and the pattern of middle Pleistocen...
Archer, Will; Presnyakova, Darya; Aldeias, Vera; Colarossi, Debra; Hutten, Louisa; Lauer, Tobias; Porraz, Guillaume; Rossouw, Lloyd; Shaw, MatthewPatterns of so-called modern human behavior are increasingly well documented in an abundance of Middle Stone Age archaeological sites across southern Africa. Contextualized archives directly preceding the southern African Middle Stone Age, however, remain scarce. Current understanding of the terminal Acheulean in southern Africa derives from a small number of localities that are predominantly in the central and...
The evolution of pyrotechnology in the Upper Palaeolithic of Europe
Murphree, William; Aldeias, VeraPyrotechnology, the ability for hominins to use fire as a tool, is considered to be one of the most important behavioural adaptations in human evolution. While several studies have focused on identifying the emergence of fire use and later Middle Palaeolithic Neanderthal combustion features, far fewer have focused on modern human fire use. As a result, we currently have more data characterizing the hominin fire...
Carbon, nitrogen, and oxygen stable isotopes in modern tooth enamel: A case stu...
Lüdecke, Tina; Leichliter, Jennifer N.; Aldeias, Vera; Bamford, Marion K.; Biro, Dora; Braun, David R.; Capelli, Cristian; Cybulski, Jonathan D.The analyses of the stable isotope ratios of carbon (delta C-13), nitrogen (delta N-15), and oxygen (delta O-18) in animal tissues are powerful tools for reconstructing the feeding behavior of individual animals and characterizing trophic interactions in food webs. Of these biomaterials, tooth enamel is the hardest, most mineralized vertebrate tissue and therefore least likely to be affected by chemical alterat...
