Birmingham University Radiocarbon Dates X

Abstract: The following list of dates contains the majority of measurements made during 1975, ie, since our last list (R, 1975, v 17, p 255-275 Sample preparation and pretreatment continue as before (R, 1969, v 11, p 263). Where sample size was insufficient for full pretreatment or where the sample required special treatment, details accompany the result. All bone samples in this list were pretreated using the collagen extraction method of Longin (1971). ACKNOWLEDGMENTS

“…BC (Rivoli-Chiozza phase), and 4,360-3,690 cal. BC (Rivoli-Castelnovo phase) (Shotton et al, 1970;Skeates, 1994a;Williams and Johnson, 1976). Although the late phase of the Square Mouthed and the Lagozza cultures are considered to be Late Neolithic (Bagolini, 1993), for the purpose of consistency with previous studies, the data from Rivoli will be grouped as Middle…”

“…(Birm 660) and 11,110 t 210 B.P. (Birm 661) (Williams & Johnson 1976). These ages are unexpectedly young, but in view of uncertainties about their precise stratigraphic position and their long storage in a museum (Smith et al 1977), it would be unwise to use these ages other than as confirming the Late Devensian age of the raised beach fragment (at about 11 rn) in or on which they were found.…”
