Lyon Natural Radiocarbon Measurements X

Abstract

This list includes most of the measurements made since the beginning of the compilation of our previous list (R, 1983, v 25, p 59–126), in 1982 and 1983, as well as some earlier measurements of extended geologic or archaeologic studies.

Mixed occupation during the Middle Palaeolithic: Case study of a small pit-cave-site of Les Pêcheurs (Ardèche, south-eastern France)

“…The bones from the upper part of the sequence, at a depth of 210 and 300 cm, associated with Aurignacian and Mousterian levels were dated. Although some technical problems occurred at that time, the radiocarbon results gave dates between 24 ka and >31 ka BP (Evin et al, 1985). More recently, bones from Sector 4 were dated again by U/Th and suggest an age spanning between 120 and 40 ka BP.…”

“…Radiocarbon dates, ESR and U/Th, in the archaeological sequence of Les Pêcheurs(Evin et al, 1985;Masaoudi et al, 1994)-all ages in ka…”

A radiocarbon chronology for the complete Middle to Upper Palaeolithic transitional sequence of Les Cottés (France)

“…Les Cottés is best known for its well preserved Aurignacian industry with split-based points and as the type site for "Les Cottés point" lithics from the so-called "evolved" variant of the Châtelperronian (Pradel, 1963). During Pradel's research, conventional radiocarbon dates were obtained on teeth and bone from the site (Evin et al, 1985;Pradel, 1967;Vogel and Waterbolk, 1967). However, the teeth and bone used for dating had been coated in a turpentine solution saturated with beeswax which likely influenced the obtained ages (Evin et al, 1985;Vogel and Waterbolk, 1967) which are listed in Table 1.…”

“…The production (2273 numbered lithics, Table 2) is orientated towards the production of rectilinear blades. Among the 23 Châtelperronian cores, none of them show an organized flake production and instead they all show blade production characteristic of the Châtelperronian (Connet, 2002; (Evin et al, 1985;Pradel, 1967;Vogel and Waterbolk, 1967 Pelegrin, 1995). Blades are unipolarly removed by sequential series, on both narrow and wide surfaces (Roussel, 2011).…”

Datations SMA et nouveaux regards sur l’archéo-séquence du Rond-du-Barry (Polignac, Haute-Loire)

“…3) (Debard et Virmont, 1976 ;Évin et al, 1985). On note ici la plus forte diversité de types de silex génétiques (n = 59), majoritairement semi-locaux (entre 15 et 90 km) (38,7 %) et locaux (< 15 km) (34,9 %).…”
