The Uluzzian in the north of Italy: insights around the new evidence at Riparo Broion

In attempt to enlighten the debate on the Middle to Upper Palaeolithic transition, this work contributes new data from a yet unpublished site, Riparo Broion in the north-east of Italy. Studies confirm the presence of the Uluzzian technocomplex embedded in an archaeological sequence which includes Mousterian, Gravettian and Epigravettian. These layers have yielded finds of bone and lithic technology, shell beads, engraved portable art and the use of red mineral pigments, which make this archive a unique case for evaluating the implications of cultural dynamics in Northern Italy 44.0\u201342.4 ky BP. The diversity of the faunal assemblage recovered in layers 1f and 1g is representative of the different environments surrounding the site, with ungulates being targeted for hunting and consumption. The lithic assemblage records a high fragmentation rate due to the extensive use of the bipolar knapping technique, responsible for a large variety of splintered pieces and associated chips which also affected the backed pieces, lunates and end-scrapers. The features of the bone tools, as well as those of the marine and freshwater beads, echo the technique used in the Uluzzian in the south of Italy, confirming the geographic spread of this technocomplex in the North Adriatic region, as previously envisaged at Grotta Fumane. However, comparisons between these two sites stimulate a discussion around the possible driving forces responsible for the differences observed in technological, typological and structural lithic assemblages. A definitive scenario for the Middle Palaeolithic\u2013Upper Palaeolithic transition in this region of Southern Europe is ongoing and Riparo Broion is adding key contributions

Bears and Humans, a Neanderthal tale. Reconstructing uncommon behaviors from zooarchaeological evidence in Southern Europe

Cave bear (Ursus spelaeus), brown bear (Ursus arctos), and Neanderthals were potential competitors for environmental resources (shelters and food) in Europe. In order to reinforce this view and contribute to the ongoing debate on late Neanderthal behavior, we present evidence from zooarchaeological and taphonomic analyses of bear bone remains discovered at Rio Secco Cave and Fumane Cave in northeast Italy, an extended geographic area north of the Adriatic Sea. The remains from both caves come from layers dated to 49-42 ky cal. BP, and suggest close interactions between humans and bears, with data not only limited to the association of Mousterian lithic artifacts with numerous bear remains, but also the detection of clearly preserved traces of human modification such as cut and percussion marks, which enable a reconstruction of the main steps of fur recovery and the butchering process. Examples of Neanderthal bear exploitation are extremely sporadic in Europe, and Grotta Rio Secco and Grotta Fumane can be considered rare cases of remain accumulations generated by the human predation of bears of varied age classes during or near the end of hibernation. All of this evidence suggests that bears had a strategic role in the nomadic economy of Neanderthal hunting groups

Late Neanderthal subsistence at San Bernardino Cave (Berici Hills-Northeastern Italy) inferred from zooarchaeological data

North-eastern Italy is a key region for the study of Neanderthal way of life over a wide timeframe, as attested by over 20 Middle Palaeolithic multi-layered sites in caves, rock shelters and at open-air sites. Here we contribute to increase our understanding of Neanderthal subsistence strategies through the study of the faunal assemblage of Unit II dated to the first half of Marine Isotopic Stage 3 (MIS3), from San Bernardino Cave. The site is located in the Berici Hills, at low altitude near the edge of a karstic plateau dissected by valleys and delimited by the alluvial lowland. Zooarchaeological and taphonomic analyses suggest that Neanderthal groups were the primary agent for the accumulation of mammal remains, and that hunting mainly focused on ungulates, such as Cervus elaphus and Capreolus capreolus. Forested environment sustained by mild climatic conditions is also inferred by micromammals evidence. Our data suggest a selective transport of the prey - even for the roe deer - which might have implied a long distance transportation from the site. Also, it might have been related to the age of the prey or to multiple preys hunted in a single episode. The Bayesian method applied to the analysis of skeletal profiles shows a high level of attrition at the site and a greater degree of processing appendicular skeleton. Neanderthals used San Bernardino Cave as a place where carcasses processing was finalized, after an initial process at the kill-site, and then prepared for consumption. Also, discarded bones were used for lithic manufacturing. The San Bernardino evidence can be compared with productive systems for exploiting available ungulate game from other regional-scale MIS 3 Middle Palaeolithic sites.Excavations and studies at San Bernardino Cave are coordinated by the University of Ferrara (M.P.) and supported by the Ministry of Cultural Affairs and Tourism and Veneto Archaeological Superintendency (SABAPVerona, Vicenza and Rovigo), public institutions (Veneto Region - Department for Cultural Heritage, Province of Vicenza, Municipality of Mossano).

The Biarzo case in northern Italy: Is the temporal dynamic of swine mitochondrial DNA lineages in Europe related to domestication?

Genetically-based reconstructions of the history of pig domestication in Europe are based on two major pillars: 1) the temporal changes of mitochondrial DNA lineages are related to domestication; 2) Near Eastern haplotypes which appeared and then disappeared in some sites across Europe are genetic markers of the first Near Eastern domestic pigs. We typed a small but informative fragment of the mitochondrial DNA in 23 Sus scrofa samples from a site in north eastern Italy (Biarzo shelter) which provides a continuous record across a ≈6,000 year time frame from the Upper Palaeolithic to the Neolithic. We additionally carried out several radiocarbon dating. We found that a rapid mitochondrial DNA turnover occurred during the Mesolithic, suggesting that substantial changes in the composition of pig mitochondrial lineages can occur naturally across few millennia independently of domestication processes. Moreover, so-called Near Eastern haplotypes were present here at least two millennia before the arrival of Neolithic package in the same area. Consequently, we recommend a re-evaluation of the previous idea that Neolithic farmers introduced pigs domesticated in the Near East, and that Mesolithic communities acquired domestic pigs via cultural exchanges, to include the possibility of a more parsimonious hypothesis of local domestication in Europe

An overview of Alpine and Mediterranean palaeogeography, terrestrial ecosystems and climate history during MIS 3 with focus on the Middle to Upper Palaeolithic transition

This paper summarizes the current state of knowledge about the millennial scale climate variability characterizing Marine Isotope Stage 3 (MIS 3) in S-Europe and the Mediterranean area and its effects on terrestrial ecosystems. The sequence of Dansgaard-Oeschger events, as recorded by Greenland ice cores and recognizable in isotope profiles from speleothems and high-resolution palaeoecological records, led to dramatic variations in glacier extent and sea level configuration with major impacts on the physiography and vegetation patterns, both latitudinally and altitudinally. The recurrent succession of (open) woodlands, including temperate taxa, and grasslands with xerophytic elements, have been tentatively correlated to GIs in Greenland ice cores. Concerning colder phases, the Greenland Stadials (GSs) related to Heinrich events (HEs) appear to have a more pronounced effect than other GSs on woodland withdrawal and xerophytes expansion. Notably, GS 9-HE4 phase corresponds to the most severe reduction of tree cover in a number of Mediterranean records. On a long-term scale, a reduction/opening of forests throughout MIS 3 started from Greenland Interstadials (GIs) 14/13 (ca. 55\u201348 ka), which show a maximum in woodland density. At that time, natural environments were favourable for Anatomically Modern Humans (AMHs) to migrate from Africa into Europe as documented by industries associated with modern hominin remains in the Levant. Afterwards, a variety of early Upper Palaeolithic cultures emerged (e.g., Uluzzian and Proto-Aurignacian). In this chronostratigraphic framework, attention is paid to the Campanian Ignimbrite tephra marker, as a pivotal tool for deciphering and correlating several temporal-spatial issues crucial for understanding the interaction between AMHs and Neandertals at the time of the Middle to Upper Palaeolithic transition

Integrated multidisciplinary ecological analysis from the Uluzzian settlement at the Uluzzo C Rock Shelter, south-eastern Italy

open20siThe Middle to Upper Palaeolithic transition, between 50 000 and 40 000 years ago, is a period of important ecological and cultural changes. In this framework, the Rock Shelter of Uluzzo C (Apulia, southern Italy) represents an important site due to Late Mousterian and Uluzzian evidence preserved in its stratigraphic sequence. Here, we present the results of a multidisciplinary analysis performed on the materials collected between 2016 and 2018 from the Uluzzian stratigraphic units (SUs) 3, 15 and 17. The analysis involved lithic technology, use-wear, zooarchaeology, ancient DNA of sediments and palaeoproteomics, completed by quartz single-grain optically stimulated luminescence dating of the cave sediments. The lithic assemblage is characterized by a volumetric production and a debitage with no or little management of the convexities (by using the bipolar technique), with the objective to produce bladelets and flakelets. The zooarchaeological study found evidence of butchery activity and of the possible exploitation of marine resources, while drawing a picture of a patchy landscape, composed of open forests and dry open environments surrounding the shelter. Ancient mitochondrial DNA from two mammalian taxa were recovered from the sediments. Preliminary zooarchaeology by mass spectrometry results are consistent with ancient DNA and zooarchaeological taxonomic information, while further palaeoproteomics investigations are ongoing. Our new data from the re-discovery of the Uluzzo C Rock Shelter represent an important contribution to better understand the meaning of the Uluzzian in the context of the Middle/Upper Palaeolithic transition in south-eastern Italy.First published: 13 July 2021openSARA SILVESTRINI, MATTEO ROMANDINI, GIULIA MARCIANI, SIMONA ARRIGHI, LISA CARRERA, ANDREA FIORINI, JUAN MANUEL LÓPEZ-GARCÍA, FEDERICO LUGLI, FILOMENA RANALDO, VIVIANE SLON, LAURA TASSONI, OWEN ALEXANDER HIGGINS, EUGENIO BORTOLINI, ANTONIO CURCI, MATTHIAS MEYER, MICHAEL CHRISTIAN MEYER, GREGORIO OXILIA, ANDREA ZERBONI, STEFANO BENAZZI, SPINAPOLICE ENZA ELENASARA SILVESTRINI, MATTEO ROMANDINI, GIULIA MARCIANI, SIMONA ARRIGHI, LISA CARRERA, ANDREA FIORINI, JUAN MANUEL LÓPEZ-GARCÍA, FEDERICO LUGLI, FILOMENA RANALDO, VIVIANE SLON, LAURA TASSONI, OWEN ALEXANDER HIGGINS, EUGENIO BORTOLINI, ANTONIO CURCI, MATTHIAS MEYER, MICHAEL CHRISTIAN MEYER, GREGORIO OXILIA, ANDREA ZERBONI, STEFANO BENAZZI, SPINAPOLICE ENZA ELEN

Backdating systematic shell ornament making in Europe to 45,000 years ago.

Personal ornaments are commonly linked to the emergence of symbolic behavior. Although their presence in Africa dates back to the Middle Stone Age, evidence of ornament manufacturing in Eurasia are sporadically observed in Middle Palaeolithic contexts, and until now, large-scale diffusion has been well documented only since the Upper Palaeolithic. Nevertheless, little is known during the period between ca. 50,000 and 40,000 years ago (ka), when modern humans colonized Eurasia replacing existing hominin populations such as the Neandertals, and a variety of “transitional” and/or early Upper Palaeolithic cultures emerged. Here, we present shell ornaments from the Uluzzian site of Grotta del Cavallo in Italy, southern Europe. Our results show evidence of a local production of shell beads for ornamental purposes as well as a trend toward higher homogeneity in tusk bead shape and size over time. The temporal interval of the layers of interest (45–40 ka) makes Cavallo the earliest known shell ornament making context in Europe

Human talar ontogeny: Insights from morphological and trabecular changes during postnatal growth

The study of the development of human bipedalism can provide a unique perspective on the evolution of morphology and behavior across species. To generate new knowledge of these mechanisms, we analyze changes in both internal and external morphology of the growing human talus in a sample of modern human juveniles using an innovative approach. The sample consists of high‐resolution microCT scans of 70 modern juvenile tali, aged between 8 postnatal weeks and 10 years old, from a broad chronological range from Middle/Late Neolithic, that is, between 4800 and 4500 BCE, to the 20th century. We applied geometric morphometric and whole‐bone trabecular analysis (bone volume fraction, degree of anisotropy, trabecular number, thickness, and spacing) to all specimens to identify changes in the external and internal morphology during growth. Morphometric maps were also generated. During the first year of life, the talus has an immature and globular shape, with a dense, compact, and rather isotropic trabecular architecture, with numerous trabeculae packed closely together. This pattern changes while children acquire a more mature gait, and the talus tends to have a lower bone volume fraction, a higher anisotropy, and a more mature shape. The changes in talar internal and external morphologies reflect the different loading patterns experienced during growth, gradually shifting from an “unspecialized” morphology to a more complex one, following the development of bipedal gait. Our research shows that talar plasticity, even though genetically driven, may show mechanical influences and contribute to tracking the main locomotor milestones
