“…Boraginaceae) and its potential for paleoclimate research. Previously, biogenic carbonate in fruits of flowering plants has been studied isotopically in the genus Celtis (Wang et al, 1997;Jahren et al, 1998Jahren et al, , 2001. These works addressed the processes of biomineralization in fruit tissues (Jahren et al, 1998) as well as the radiocarbon content (Wang et al, 1997) and oxygen isotopic composition (Jahren et al 2001) of fruit carbonate.…”

It has been demonstrated that the δ 18 O values of biogenic carbonate in Celtis fruits are correlated to δ 18 O of local meteoric water and, for the studied ecological range, also to mean annual temperatures (Jahren et al, 2001).…”

“…Our analyses confirm the prevalence of carbonates in the fruit walls of both fossil and modern specimens. The Celtis modern fruits we studied are mostly composed of aragonite, as is expected for modern material (Cowan et al 1997;Wang et al 1997;Jahren et al 1998). Fruit endocarps of Celtis are formed of a silica framework associated with aragonite deposits, even though silica opal structures may be lacking.…”

“…The second group corresponds to fossils that have been preserved because some living plants have the capacity to produce mineral matter, i.e., biomineralisation processes in organisms before deposition and burial. Carbonates are most commonly involved in such mineralisation, along with silica (Wang et al 1997;Jahren et al 1998Jahren et al , 2001Pustovoytov et al 2004;Pustovoytov and Riehl 2006). As mineralised fruits or seeds are commonly collected in archaeological sites or natural deposits, their specific preservation status has to be taken into account and studied.…”

Mineralised fruits and seeds are frequently found in archaeological sediments but their chemical nature has not been often examined. The nature and the origin of these archaeobotanical remains have to be investigated to understand their taphonomic history. Fruits or seeds can be mineralised not only by replacement mineralisation but also by biomineralisation during the plant life. The mineral components of three fossil fruits sampled on the Pleistocene site of Dmanisi were analysed and compared with their modern analogues. Analyses were carried out by means of an environmental scanning electron microscope, equipped with an energy dispersive X-ray device and by means of a Fourier transform infrared spectrometer. Biogenic carbonates and/or biogenic silica were identified in the fossil and modern fruits of some taxa. Comparison between fossil and modern specimens has shown that molecular reorganisation occurred in carbonate and in biogenic silica during fossilisation, through diagenetic processes. The resulting stable mineral structures confer an exceptional preservation to fruits in sediments. Taking into account these taphonomic specificities (transformation and differential preservation), the chronological and palaeoenvironmental aspects of the mineralised fruits are discussed.

Could the central‐eastern Iberian Mediterranean region be defined as a refugium? Fauna and flora in MIS 5–3 and their implications for Palaeolithic human behaviour

Neanderthals and modern humans from the Early Upper Palaeolithic had a highly developed knowledge of their environment, where they found the essential resources for their subsistence. Therefore, changes in the local landscape and available resources should have influenced their behaviour, as indicated by faunal and plant remains recovered from archaeological sites. In the central‐eastern Iberian Mediterranean region, the archaeological sites of Cova Negra, Abrigo de la Quebrada, Cova de les Malladetes and Cova de les Cendres have provided wood charcoal, seeds and fauna. The combination of these data allows an accurate reconstruction of the regional landscape from MIS 5 to the beginning of MIS 2. The available evidence suggests that this region could be defined as a refugium in which biodiversity persisted. This type of refugium, containing a high diversity of biotopes and some endemic species, which has lasted until the present day, can be seen at a regional scale, but also locally, especially near the coast. These special characteristics of the region – relatively stable climatic conditions with oscillations mainly in aridity and humidity, and a high diversity of flora and fauna – could explain the high density of Palaeolithic sites throughout Middle and Upper Palaeolithic here.
