GC-MS analysis of soil faecal biomarkers uncovers mammalian species and the economic management of the archeological site "Le Colombare di Negrar"

: The identification of the mammalian species based on faecal sediments in modern and ancient environments is the aim of the research of archaeologists, forensic scientists and ecologists. Here, we set up and validated an optimized gas chromatography-mass spectrometry (GC-MS) method, characterized by a time-saving sample preparation protocol, for the simultaneous analysis of faecal biomarkers (6 sterols/stanols and 5 bile acids) in 14 soil samples from the archaeological site of "Le Colombare di Negrar" in northern Italy. Although the archaeological sediment samples examined are numerically exiguous, a comparative reading of our faecal biomarkers findings with new studies on faunal materials collected in the same stratigraphic detail during recent excavation campaigns will allow to better clarify the economic interest of the animal species farmed in the Colombare site (such as bovines, goats, sheep and pigs) and to shed light on the management of breeding. Together with archaeozoological and archaeobotanical analyses, the investigation of faecal biomarkers can increase our knowledge of how ancient local communities exploited natural resources and may allow us to deduce what their impact on the landscape was

Palaeoenvironment, Settlement, and Land Use in the Late Neolithic—Bronze Age Site of Colombare di Negrar di Valpolicella (N Italy, On-Site)

Palynological and archaeobotanical analyses have been carried out as part of the interdisciplinary project of Colombare di Negrar, a prehistoric site in the Lessini Mountains (northern Italy). The palaeoenvironmental and economic reconstruction from the Late Neolithic to the beginning of the Early Bronze Age was based on 16 pollen samples and three samples of macroremains taken from two contiguous trenches. The landscape reconstruction shows the presence of natural clearings in the wood. Forest cover was characterised by oak wood, with Ulmus and Tilia. The intermediate morphology of size and exine of Tilia cordata/platyphyllos pollen may be regarded as the first palynological evidence of lime hybrids in palaeorecords. Hygrophilous trees and Vitis vinifera testify to the presence of riparian forests and moist soils. Among trees supplying fruits, in addition to the grapevine, hazelnut (Corylus avellana) and walnut (Juglans regia) were present. A mixed economy based on animal breeding and cultivation of cereals (Hordeum vulgare, Triticum monococcum, T. dicoccum, T. timopheevii) emerged from the data. The combined analysis of pollen and plant macroremains suggests that different activities were carried out simultaneously in Colombare and a relationship between natural resources and the socio-economic and cultural evolution of the territory

LA PALAFITTA DI TOMBOLA DI CEREA (VR). LO SCAVO 1999.

La palafitta \ue8 stata scoperta nel 1955 all'interno della Valle del Menago, poche centinaia di metri a Sud del gruppo di case di Tombola di Cerea (VR). Dopo un primo scavo effettuato nello stesso anno da parte di Francesco Zorzi, direttore del Museo Civico di Storia Naturale di Verona, le ricerche sono riprese nel 1999 da parte della Soprintendenza Archeologica del Veneto. I risultati di queste ricerche hanno accertato che l'abitato preistorico era posto su palafitta all'interno di un ambiente di tipo palustre. Sono conservati solo dei pali verticali e alcune travi orizzontali, che fanno ipotizzare l'esistenza di una piattaforma lignea. Gli elementi strutturali della palafitta trovano confronti in altri abitati d'ambiente umido della media et\ue0 del Bronzo. L\u2019inquadramento geomorfologico finalizzato alla ricostruzione paleogeografica mostra che il sito si colloca al centro della Paleovalle del f. Menago, un\u2019incisione larga alcune centinaia di metri e profonda oltre una decina di metri, alla base di un potente spessore di torbe. Gli studi pregressi, relativi all\u2019origine della profonda incisione generata dall\u2019omonimo fiume di risorgiva, si richiamano principalmente a fattori geodinamici legati a linee tettoniche sepolte, quali moventi principali per le incisioni causate dalle diversione di canali di rotta atesini richiamati verso il bacino delle Valli Grandi Veronesi, verificatesi in et\ue0 tardoglaciale-olocenica antica. L\u2019analisi di nuove litostratigrafie rilevate su esposizioni individuate all\u2019interno della paleovalle, ha condotto a riscontrare la presenza di uno spesso e pressoch\ue9 continuo riempimento di sedimenti organico-torbosi, che contrassegnano gli accrescimenti e le sedimentazioni verificatesi a partire dai livelli basali della stazione palafitticola, deposizioni che sono perdurate sino a date piuttosto recenti. Una serie di dettagliati confronti operati con i termini delle sequenze di riempimento torboso-detritiche del bacino che si sviluppava all\u2019esterno delle arginature del vicino e coevo sito di Fondo Paviani, ha portato a verificare un\u2019analoga evoluzione negli accrescimenti che contrassegnano i tratti superiori di queste due importanti successioni alluvio-organiche. Si giunge in definitiva a far intervenire una medesima incidenza di fattori antropici e climatici quali concause principali nello sviluppo dei riempimenti sommitali della Paleovalle del Menago, in corrispondenza della stazione palafitticola della Tombola di Cerea e del sito arginato di Fondo Paviani. Lo scavo ha restituito un notevole quantitativo di materiale ceramico (ca. 620 kg) e una percentuale minoritaria di manufatti in bronzo, terracotta e osso-corno. Il presente contributo si concentra sull'analisi crono-tipologica dei materiali focalizzando l'attenzione sulla ceramica di impasto medio-fine ai fini dell'inquadramento complessivo e del confronto con materiale proveniente da siti geograficamente limitrofi. Le datazioni assolute delle strutture lignee, ottenute dall\u2019applicazione della dendrocronologia e dal radiocarbonio, collocano gli elementi verticali di Tombola di Cerea nella seconda met\ue0 del XV secolo cal BC, o al pi\uf9 tardi nei primi decenni del XIV secolo cal BC; essi sono stati ottenuti da alberi di quercia abbattuti in momenti successivi, a intervalli di circa 10 anni. Le ricerche archeobotaniche hanno compreso un\u2019analisi palinologica condotta su 18 campioni presi da una carota prelevata all'interno dell\u2019abitato palafitticolo, ed un\u2019analisi carpologica e xilo-antracologica su due campioni provenienti da unit\ue0 stratigrafiche cronologicamente corrispondenti alla parte basale della carota. L\u2019analisi dei resti vegetali ha permesso di disegnare il quadro ambientale dell\u2019insediamento. Il luogo era ricco di ambienti umidi soprattutto ripariali, con boscaglie d\u2019igrofile e con elofite, con situazioni di prati periodicamente inondati e fossati poco profondi. La presenza antropica \ue8 suggerita dalla coltivazioni di cereali e altri indicatori antropogenici. Inoltre i dati carpologici e/o pollinici testimoniano la disponibilit\ue0 nell\u2019area di varie piante con frutti eduli, come prugnolo, nocciolo, ribes, noce e vite. Il ritrovamento di reperti di Baldellia ranuncoloides -una specie oggi minacciata sottolinea come le ricerche archeobotaniche forniscano informazioni anche dal punto di vista naturalistico utili per conoscere meglio la storia di specie oggi in rarefazione. L\u2019insieme faunistico \ue8 composto complessivamente da 1995 reperti ossei. Quasi l\u201980% dei resti \ue8 stato identificato a livello specifico. La maggior parte dei resti appartiene alle specie domestiche: bue, pecora, capra e maiale, seguite da cavallo e cane. La distribuzione delle classi d\u2019et\ue0 mostra come l\u2019allevamento degli Ungulati fosse finalizzato non solo all\u2019ottenimento di carni, ma anche alla produzione di latte e lana. La pratica della caccia, volta allo sfruttamento di specie di ambiente forestale (cervo, capriolo, cinghiale), appare un\u2019attivit\ue0 marginale. Le tracce di macellazione sono numerose e attestano l\u2019utilizzo di strumenti sia litici sia metallici. Durante lo studio sono stati riconosciuti 18 manufatti in materia dura animale, ben conservati, che hanno permesso l\u2019identificazione delle tracce di lavorazione utili per la ricostruzione delle catene operative.The pile dwelling was discovered in 1955 in the valley of the river Menago, just a few hundred meters south of the settlement of Tombola di Cerea (VR). A first excavation was carried out that very year by Francesco Zorzi, director of the Museo Civico di Storia Naturale of Verona; the digging has been resumed in 1999 by the Soprintendenza Archeologica of Veneto. The results of these excavations have ascertained that the prehistoric dwelling site was built in a marshy environment. Only some vertical poles and some horizontal beams were preserved, which leads to the hypothesis that there existed a wooden platform on which the sheds were standing. The structural elements of the palafitte find correspondents in others settlements in moist environment from the Middle Bronze Age. The paleogeographic reconstruction of the immediate hinterland confirm the location of the site at the center of the Menago River Paleovalley, an incision a few hundred meters wide and more than ten meters deep, at the base of a thick layer of peat. Previous studies, related to the origin of the deep incision generated by the homonymous spring-line river, mainly refer to geodynamic factors linked to buried tectonic lines, as main motives for the incisions caused by the diversion of Adige breach-channels captured towards the basin of Great Veronese Valleys, which occurred in the late Lateglacial-Holocene age. The analysis of new lithostratigraphies detected on exposures inside the paleovalley, has led to find the presence of a thick and almost continuous filling of organic-peaty sediments, which mark the accretions and the sedimentations verified starting from the basal levels of the pile-dwelling site, depositions that have lasted until fairly recent dates. A series of detailed comparisons made with the terms of the peat-debris-filling sequences of the basin that developed outside the embankments of the near and coeval Fondo Paviani site, led to verify a similar evolution in the growths that mark the upper reaches of these two important alluvio-organic successions. Ultimately, is claimed that the same incidence, of anthropogenic and climatic factors, is involved as the main contributors to the development of the upper fills of the Menago Paleovalley, in correspondence with the pile-dwelling station of the Tombola di Cerea and the embanked site of Fondo Paviani. A great number of ceramic fragments (ca 620 kg) and a smaller amount of bronze, terracotta and bone-horn artefacts had been found. This paper focus on chrono-typological analysis of the archaeological finds, in particular on ceramic of the medium-fine tipe. The goal is the overall classification artefacts, accompanied by a comparison made from materials found in geographically nearbysites. Dendrochronology and radiocarbon allow to date the wooden structures to the second half of the 15th Century cal BC, or in the first decades of the 14th Century cal BC at the latest; the vertical posts come from oak tree felled down once about every ten years. Archaeobotanical study includes pollen analysis carried out on 18 subsamples taken from a core collected in the pile-dwelling settlement and carpological and xilo-anthacological analysis, from 2 samples taken from layers (stratigraphic units) corresponding to the bottom of the core. The results allows to draw the environmental framework of the settlement. The pollen diagram shows that the landscape was rich of wet environments: ponds, wet grassland and hygrophilous wood. The human activity was suggested by a number of anthropogenic indicators: cereal fields, ruderals and weeds. Seeds/fruits and pollen data testify to the presence in the area of edible fruits from plants such as blackthorn, hazelnut, currant, walnut and grapevine. The finds of Baldellia ranuncoloides \u2013 a threatened plants today - underline that the archaeobotanical research provide naturalistic information that allow us to better understand the history of plant species becoming rare today. The faunal assemblage is composed by 1995 bone remains. More than 80% of the faunal remains was identified at species level. Domestic animals are the most frequent. Age at death highlights different breeding strategies focused on meat consumption and secondary products. Hunting was barely practiced on wild ungulates (red deer, roe deer, wild boar). Several anthropic marks were identified on the faunal remains emphasizing the use of lithic and metal tools. During the analysis 18 animal hard material artefacts were identified. The good state of preservation allowed us to identify working traces linked to the reduction sequences of the tools

Radiocarbon Dating of the Early Bronze Age Cemetery at Arano, Verona, Northern Italy

Seventeen of the 73 individuals buried in the Early Bronze Age (EBA) cemetery at Arano di Cellore di Illasi, near Verona, northern Italy, were radiocarbon dated by accelerator mass spectrometry (AMS). Bayesian modeling of the calibrated dates suggests that the cemetery was probably used over several generations mainly within the first 2 centuries of the 2nd millennium cal BC. Burial activity was therefore mainly restricted to within the EBA I B/EBA I C of the north Italian Bronze Age chronology. An isolated burial, found ∼90 m northwest of the cemetery, may date to the same period

Il sito di Arano (Illasi-Verona, scavo 2007) alla luce delle trasformazioni sociali, economiche, tecnologiche, tra età del Rame e Bronzo Antico in Italia settentrionale.

L’analisi del sito di Arano si concentra nei primi 5 capitoli. La cronologia delle frequentazioni comprende l’età del Rame e l’antica età del Bronzo, e la quantità di elementi da considerare ed analizzare, nella loro specificità e complessità, è senza dubbio notevole. Il Capitolo 6 rappresenta il tentativo di enfatizzare l’importanza del dato archeometallurgico, perchè emerso in un contesto così particolare come quello dell’area nord-orientale dell’Italia settentrionale, ricca di depositi minerari conosciuti e sfruttati, ai quali però non è possibile riferire la materia prima con cui sono stati realizzati i materiali in metallo del sito. Il Cap. 7 riguarda la contestualizzazione della necropoli dell’antica età del Bronzo nel quadro dei pochi rinvenimenti funerari coevi conosciuti in Italia settentrionale. L’areale e la cronologia portano a riferire Arano alla Cultura di Polada, della quale ho cercato di mettere in evidenza problematiche, lacunosità, contraddizioni. Il Cap. 8 rappresenta, infine, un approfondimento sulle necropoli e i gruppi culturali coevi a nord dell’arco alpino, in particolare quelli stanziati in area danubiano-carpatica, con una selezione necessariamente parziale e soggettiva dei contesti di confronto

L'insediamento di Lugo di Grezzana (Verona) nel quadro del primo Neolitico padano alpino

SUMMARY - The settlement of Lugo di Grezzana in the framework of the Early Neolithic Po vall ey - The Lugo di Grezzana (Verona) deposit is located in the Lessini Mountains and represents one of the key sites to decipher the occupation and raw material exploitation strategies between the end of the 6th and the beginning of the 5th millennium BC. The results of the research directed by the University of Trento in collaboration with the Soprintendenza per i beni archeologici del Veneto (Archaeological Heritage of Veneto Region) are presented in this paper. The study of the stratigraphy and material culture supported by 14C datings (tab. I, fig. 3) suggest an increasing occupation of the area with some lack or shift stressed by alluvial lenticular layers. A single date is attributable to mid 6th millennium cal BC and can be interpreted as the first early occupation of the area. The artefact complex (figg. 4-7) found at the bottom of the large pit ES 116/03 (units 260/03, 259/03, 256/03) are attributed to this phase and characterised by the absence of the Ripabianca burin and of the Fiorano carenated beaker. The main occupation is dated 5300-5000 cal BC which is the period of the maximum diffusion of the Lessini chart all over Northern Italy. Around 5000 cal BC the occupation of the settlement seems to show a temporary interruption and alluvial events are evident in all the pits. The last Neolithic occupation is attested between the 4900 and 4800/4700 cal BC when the early geometric-linear style of Square Mouthed Pottery culture is already widespread. This phase is scanty represented by chipping areas and simple round fire places
