Floteringprodukt med trækul, korn eller frø er returneret og magasineret.
Materiale udtaget til AMS-datering.
AMS-datering modtaget 19. marts 2009 med følgende oplysninger:
AAR-12765
Type: Charcoal (hassel/el)
Indsamlingsoplysninger: Rynkeby Mølle 09.01.08 sb. 159, Ringe sogn, Svendborg Amt.
Prøve af trækul udtaget til datering. Fundet hidrører fra et et-skibet langhus med svagt buede langvægge, der typologisk er dateret overgangen yngre vikingetid til ældre middelalder. Dateringen ses som et led i at opbygge en bredere kronologi/forståelse for middelalderens mange hustyper.
Vedbestemmelse (FHM): Prøven bestå af > 100 stk. små trækulsstykker, heriblandt Fagus, bøg 6 stk, heraf en fra en mindre gren.
AMS-prøve, 1 stk. Alnus/corylus, Elletræ/hassel, < 5 cm uden bark, 1-2 årringe

14C ages are reported in conventional radiocarbon years BP (before present = 1950) in accordance with international convention (M. Stuiver & H.A. Polach: Discussion of reporting 14C data. Radiocarbon 19(3) (1977) p. 355).
Thus, all calculated 14C ages have been corrected for fractionation so as to refer the result to be equivalent with the standard d13C value of -25‰ (wood). Reported d13C and d15N values have been measured by high-precision stable-isotope mass spectrometry. The values represent the isotopic composition of the original sample and is therefore useful for interpretation regarding association with the terrestrial/marine/freshwater food chains as well as trophic levels.
Calibrated ages in calendar years have been obtained from the calibration curves in Reimer et al. 2004 Radiocarbon vol. 46(3) pp 1029-1058 by means of the Oxcal v4.0 calibration programme (Bronk Ramsey C., 2001, Radiocarbon, 43 (2A) 355-363) using the terrestrial calibration curve, IntCal04 (for marine samples, see below). The probability method has been used to calculate the calibrated age ranges corresponding to 68.2% probability (1 sigma) and 95.4% probability (2 sigma) with the probability of each range given in brackets (indicating the probability that the true date belongs to the interval in question).
