La Fusta. Patrimoni cultural i biològic
Wood: biological and cultural heritage. Anthracology is a branch of archaeobotany that came into being at the beginning of the 20th Century for the botanical identification of prehistoric wood and carbon. The goals are paleoecological, ethnological and methodological. The protocol followed for this analysis involves the observation of plant tissues under reflected-light microscopy and scanning electron microscopy to identify the material botanically. In recent years, this kind of analysis is being applied to heritage objects and those in restoration; here we will give some examples: an historic object, the restoration of a monument and the reconstruction of a prehistoric landscape

The fire of Iberian Neanderthals. Wood charcoal from three new Mousterian sites in the Iberian Peninsula
Neolithic woodland in the north Mediterranean basin: A review on Olea europaea L.
The aim of this paper is to specify the natural distribution of Olea europaea L. during the Early Holocene in the Northern Mediterranean by means of the identification of wood charcoal remains of this species at prehistoric sites. For this purpose, we have reviewed the relevant literature and extracted the data in which Olea charcoal has been identified. We have taken into consideration the biogeographical and chrono-cultural contexts in which the species is present, its frequency of occurrence at different locations and the associated plant taxa with the aim of tracking the Holocene history of the oleaster. Based on this information we suggest that the species started expanding during the Preboreal from Pleistocene thermophilous tree refugia located in the Levant, Cyprus, Sicily and the southern parts of the Iberian Peninsula. Its presence was confined to the thermomediterraenan bioclimatic level. The expansion dynamics of Olea after the Boreal are better understood in the western Mediterranean. There the species becomes very abundant or dominant in the thermophilous plant formations of the Atlantic period and expands to favorable enclaves outside the limits of the thermomediterraenan bioclimatic level.The aim of this paper is to specify the natural distribution of Olea europaea L. during the Early Holocene in the Northern Mediterranean by means of the identification of wood charcoal remains of this species at prehistoric sites.

Olea europaea L. in the North Mediterranean basin during the Pleniglacial and the Early–Middle Holocene
17 páginas, 5 figuras, 2 tablas.The paper aims to define the natural distribution of Olea europaea L. var sylvestris (Miller) Lehr. in the North Mediterranean basin during the Pleniglacial and the Early-Middle Holocene by means of the identification of its wood-charcoal and/or wood at prehistoric sites For this purpose we have reviewed the previously available information and we have combined it with new wood-charcoal analyses data We have taken under consideration the presence and frequency of 0 europaea L in the available wood-charcoal sequences, the characteristics of the accompanying flora, the associated chrono-cultural contexts, the broader biogeographical context and the AMS dates provided by Olea wood-charcoal or endocarps. According to the available evidence, during the Middle and Late Pleniglacial (ca 59-11.5 ka cal BP), Olea would have persisted in thermophilous refugia located in the southern areas of the North Mediterranean basin, the southern Levant and the north of Africa. The Last Glacial Maximum (ca 2218 ka cal. BP) probably reduced the distribution area of Olea. During the Preboreal and the Boreal (ca 11500-8800 cal BP) the species started to expand in the thermomediterranean bioclimatic level In the western Mediterranean, during the Atlantic period (ca 8800-5600 cal. BP), the species became very abundant or dominant in the thermophilous plant formations and expanded to favorable enclaves outside the limits of the thermomediterranean level.This study has been supported by the national projects ‘‘Late Middle Palaeolithic and Upper Palaeolithic in the central region of the Iberian Peninsula’’ (Ref. FFI2008-01200/FISO) and ‘‘PALAEOFLORA OF IBERIA II: Ecological Change as Anthropological Contingency’’ (Ref. CGL2009-06988). We are grateful to all the
wood-charcoal analysis specialists who have identified and published Olea wood-charcoals from archaeological sites. We are also thankful to the directors of excavations from which we report unpublished material for allowing us to study the wood-charcoal
remains at those sites. Special thanks are addressed to Isabel Figueiral for her useful comments on the manuscript and for providing
unpublished data. The authors are especially thankful to M. Stiner and J. Pigati for their kind permission to cite unpublished dating data from Klissoura Cave 1. Finally, we thank the two anonymous reviewers for their comments on an earlier version of the
manuscript.Peer reviewe
