Age and Date for Early Arrival of the Acheulian in Europe (Barranc de la Boella, la Canonja, Spain)

The first arrivals of hominin populations into Eurasia during the Early Pleistocene are currently considered to have occurred as short and poorly dated biological dispersions. Questions as to the tempo and mode of these early prehistoric settlements have given rise to debates concerning the taxonomic significance of the lithic assemblages, as trace fossils, and the geographical distribution of the technological traditions found in the Lower Palaeolithic record. Here, we report on the Barranc de la Boella site which has yielded a lithic assemblage dating to ∼1 million years ago that includes large cutting tools (LCT). We argue that distinct technological traditions coexisted in the Iberian archaeological repertoires of the late Early Pleistocene age in a similar way to the earliest sub-Saharan African artefact assemblages. These differences between stone tool assemblages may be attributed to the different chronologies of hominin dispersal events. The archaeological record of Barranc de la Boella completes the geographical distribution of LCT assemblages across southern Eurasia during the EMPT (Early-Middle Pleistocene Transition, circa 942 to 641 kyr). Up to now, chronology of the earliest European LCT assemblages is based on the abundant Palaeolithic record found in terrace river sequences which have been dated to the end of the EMPT and later. However, the findings at Barranc de la Boella suggest that early LCT lithic assemblages appeared in the SW of Europe during earlier hominin dispersal episodes before the definitive colonization of temperate Eurasia took place.

Sleeping Activity Area within the Site Structure of Archaic Human Groups: Evidence from Abric Romaní Level N Combustion Activity Areas

The identification of different prehistoric activity areas and Neanderthal behavior is one of the main research goals at the Abric Romaní site, which is a well‐preserved and microstratified Mousterian archaeological site. A conspicuous occupation surface excavated in level N yielded a remarkably preserved set of aligned combustion activity areas in the inner zone of the living surface. This set of combustion activity areas suggests analogy with sleeping‐and‐resting activity areas of modern foragers. Multidisciplinary analyses suggest (1) diachronic occupation and (2) similar use of the inner zone of the living floor. The sleeping area comprises five combustion activity areas, spaced at approximately 1 m distance from each other. A large wood imprint of travertine was found near the inner zone, suggesting an architectural remain of a prehistoric dwelling. Descriptions of archaic human sleeping activity areas are very few in Paleolithic archaeology. This identification is a proxy for estimating the number of individuals of Mousterian groups that occupied the Abric Romaní rock shelter around 55 kyr BP.

Cultural cannibalism as a Paleoeconomic system in the European Lower Pleistocene: the case of level TD6 of Gran Dolina (Sierra de Atapuerca, Burgos, Spain)

Human cannibalism is currently recorded in abundant archaeological assemblages of different chronologies. The TD6 level of Gran Dolina (Sierra de Atapuerca, Burgos), at more than 800 ka, is the oldest case known at present. The analysis of cranial and postcranial remains of Homo antecessor has established the presence of various alterations of anthropic origin (cut marks and bone breakage) related with exploitation of carcasses. The human remains do not show a specific distribution, and they appeared mixed with lithic tools and bones of other taxa. Both nonhuman and human remains show similar evidence of butchering processes. The stratigraphic evidence and the new increment of the collection of remains of Homo antecessor have led us to identify a succession of cannibalism events in a dilated temporal sequence. These data suggest that hunting strategies and human meat consumption were frequent and habitual actions. The numerous evidences of cannibalism, the number of individuals, their age profile, and the archaeostratigraphic distribution suggest that cannibalism in TD6 was nutritional. This practice, accepted and included in their social system, is more ancient cultural cannibalism than has been known until now.

Intergroup cannibalism in the European Early Pleistocene: the range expansion and imbalance of power hypotheses.

In this paper, we compare cannibalism in chimpanzees, modern humans, and in archaeological cases with cannibalism inferred from evidence from the Early Pleistocene assemblage of level TD6 of Gran Dolina (Sierra de Atapuerca, Spain). The cannibalism documented in level TD6 mainly involves the consumption of infants and other immature individuals. The human induced modifications on Homo antecessor and deer remains suggest that butchering processes were similar for both taxa, and the remains were discarded on the living floor in the same way. This finding implies that a group of hominins that used the Gran Dolina cave periodically hunted and consumed individuals from another group. However, the age distribution of the cannibalized hominins in the TD6 assemblage is not consistent with that from other cases of exo-cannibalism by human/hominin groups. Instead, it is similar to the age profiles seen in cannibalism associated with intergroup aggression in chimpanzees. For this reason, we use an analogy with chimpanzees to propose that the TD6 hominins mounted low-risk attacks on members of other groups to defend access to resources within their own territories and to try and expand their territories at the expense of neighboring groups.

Upper Palaeolithic ritualistic cannibalism at Gough's Cave (Somerset, UK): The human remains from head to toe.

A recurring theme of late Upper Palaeolithic Magdalenian human bone assemblages is the remarkable rarity of primary burials and the common occurrence of highly-fragmentary human remains mixed with occupation waste at many sites. One of the most extensive Magdalenian human bone assemblages comes from Goughs Cave, a sizeable limestone cave set in Cheddar Gorge (Somerset), UK. After its discovery in the 1880s, the site was developed as a show cave and largely emptied of sediment, at times with minimal archaeological supervision. Some of the last surviving remnants of sediment within the cave were excavated between 1986 and 1992. The excavations uncovered intensively-processed human bones intermingled with abundant butchered large mammal remains and a diverse range of flint, bone, antler, and ivory artefacts. New ultrafiltrated radiocarbon determinations demonstrate that the Upper Palaeolithic human remains were deposited over a very short period of time, possibly during a series of seasonal occupations, about 14,700 years BP (before present). The human remains have been the subject of several taphonomic studies, culminating in a detailed reanalysis of the cranial remains that showed they had been carefully modified to make skull-cups. Our present analysis of the postcrania has identified a far greater degree of human modification than recorded in earlier studies. We identify extensive evidence for defleshing, disarticulation, chewing, crushing of spongy bone, and the cracking of bones to extract marrow. The presence of human tooth marks on many of the postcranial bones provides incontrovertible evidence for cannibalism. In a wider context, the treatment of the human corpses and the manufacture and use of skull-cups at Gough Cave have parallels with other Magdalenian sites in central and western Europe. This suggests that cannibalism during the Magdalenian was part of a customary mortuary practice that combined intensive processing and consumption of the bodies with ritual use of skull-cups.

Occupational Patterns and Subsistence Strategies in Level J of Abric Romaní

The faunal analysis of level J has been carried out using a zooarcheological method with some contributions from the field of Taphonomy. The data were obtained from the anatomical and taxonomical analysis and from the structural modifications of the bones. Red deer (Cervus elaphus) and horses (Equus ferus) are the most abundant animals, although they are accompanied by other herbivores like Bos primigenius, Stephanorhinus hemitoechus and Rupicapra pyrenaica. The data indicate that level J is an anthropic accumulation with a minimal incidence of carnivores. Carcasses were selectively transported into the site, where they were processed and consumed. The temporal dimension and the possibility that the faunal assemblage may be the result of different occupational events have been also considered.

Taphonomy of Level J of Abric Romaní

The taphonomic study of level J (sublevels Ja and Jb) includes macrovertebrates, microvertebrates, wood and charcoal. The association of level J has, in general, a good state of conservation, although there are several taphonomic modifications. No mechanisms or taphonomic processes which may have distorted any of these associations have been detected. This study shows how Neanderthals were the main collecting agent of animals and wood and the main agent of modification. Moreover, the water activity (water flow, dry periods and reactivitation) were the main postdepositional agent. The burial of the remains was probably relatively fast in both sublevels. There are abundant similarities in the temporary sequences of formation in both sublevels. The fossilization process of level J is consistent with a karst taphosystem in a travertine deposit. The main feature of this taphosystem is a microenvironment characterized by a relative humid environment, marked by wet conditions and reactivations of water flows. Once the remains were buried, the fossildiagenetic phase was tremendously preservative and allowed the exceptional conservation of the remains found at the site.

Experimental Butchering of a Chimpanzee Carcass for Archaeological Purposes

Two archaeological assemblages from the Sierra de Atapuerca sites show evidence of anthropogenic cannibalism. These are the late Early Pleistocene level TD6-2 at Gran Dolina, and the Bronze Age level MIR4 in the Mirador Cave. Despite the chronological distance between these two assemblages, they share the common feature that the human remains exhibit a high frequency of anthropogenic modifications (cut marks, percussion pits and notches and peeling). This frequency could denote special treatment of bodies, or else be the normal result of the butchering process. In order to test these possibilities, we subjected a chimpanzee carcass to a butchering process. The processing was intensive and intended to simulate preparation for consumption. In doing this, we used several simple flakes made from quartzite and chert from quarries in the Sierra de Atapuerca. The skull, long bones, metapodials and phalanges were also fractured in order to remove the brain and bone marrow. As a result, about 40% of the remains showed some kind of human modification. The frequency, distribution and characteristics of these modifications are very similar to those documented on the remains of Homo antecessor from TD6-2. In case of the MIR4 assemblage, the results are similar except in the treatment of skulls. Our results indicate that high frequencies of anthropogenic modifications are common after an intensive butchering process intended to prepare a hominin body for consumption in different contexts (both where there was possible ritual behavior and where this was not the case and the modifications are not the result of special treatment).

Understanding the emergence of modern humans and the disappearance of Neanderthals: Insights from Kaldar Cave (Khorramabad Valley, Western Iran)

Kaldar Cave is a key archaeological site that provides evidence of the Middle to Upper Palaeolithic transition in Iran. Excavations at the site in 2014–2015 led to the discovery of cultural remains generally associated with anatomically modern humans (AMHs) and evidence of a probable Neanderthal-made industry in the basal layers. Attempts have been made to establish a chronology for the site. These include four thermoluminescence (TL) dates for Layer 4, ranging from 23,100 ± 3300 to 29,400 ± 2300 BP, and three AMS radiocarbon dates from charcoal samples belonging to the lower part of the same layer, yielding ages of 38,650–36,750 cal BP, 44,200–42,350 cal BP, and 54,400–46,050 cal BP (all at the 95.4% confidence level). Kaldar Cave is the first well-stratified Late Palaeolithic locality to be excavated in the Zagros which is one of the earliest sites with cultural materials attributed to early AMHs in western Asia. It also offers an opportunity to study the technological differences between the Mousterian and the first Upper Palaeolithic lithic technologies as well as the human behaviour in the region. In this study, we present a detailed description of the newly excavated stratigraphy, quantified results from the lithic assemblages, preliminary faunal remains analyses, geochronologic data, taphonomic aspects, and an interpretation of the regional paleoenvironment.

Neanderthal hunting strategies inferred from mortality profiles within the Abric Romaní sequence

Ungulate mortality profiles are commonly used to study Neanderthal subsistence strategies. To assess the hunting strategies used by Neanderthals, we studied the ages at death of the cervids and equids found in levels E, H, I, Ja, Jb, K, L and M of the Abric Romaní sequence. These levels date between 43.2 ± 1.1 ka BP (14C AMS) and 54.5 ± 1.7 ka BP (U-series). The degree of eruption and development of the teeth and their wear stages were used to determine the ages of these animals at death, and mortality profiles were constructed using these data. The equids display prime dominated profiles in all of the analyzed levels, whereas the cervids display variable profiles. These results suggest that the Neanderthals of Abric Romaní employed both selective and non-selective hunting strategies. The selective strategy focused on the hunting of prime adults and generated prime dominated profiles. On the other hand, non-selective strategies, involved the consumption of animals of variable ages, resulting in catastrophic profiles. It is likely that in the selective hunting events were conducted using selective ambushes in which it was possible to select specific prey animals. On the other hand, encounter hunting or non-selective ambush hunting may have also been used at times, based on the abundances of prey animals and encounter rates. Specific hunting strategies would have been developed accordance with the taxa and the age of the individual to be hunted. The hunting groups most likely employed cooperative hunting techniques, especially in the capture of large animals. Thus, it is not possible to uniquely associate a single mortality profile with the predation tactics of Neanderthals at Abric Romaní.
