Considering that bones are often found surrounded by different kinds of organic matter, bones are arguably one of the most highly contaminated samples submitted to AMS labs for radiocarbon dating . The common contaminants are humic and fulvic acids, which are organic acids present in soil that are produced by the microbial degradation of plant or animal tissues .
Two samples from the Sixth International Radiocarbon Intercomparison (SIRI), labeled SIRI-B (mammal) and SIRI-C (Mammoth), plus a third sample of modern bone (cow bone ) collected in Brazil in 2010, two other samples from the Centre for Nuclear Energy in Agriculture of the University of São Paulo (CENA-USP) previously dated by AMS at CAIS, University of Georgia, USA, and a fragment of human bone from a Brazilian shellmound were used in this preliminary test .
Whether or not a charred bone will yield a radiocarbon date depends on the degree of charring . Bones that have been heated in low temperatures present special considerations . Bones with charred protein can be very good samples for AMS dating . In this case, the carbon is resilient to decay and can be fully pretreated in the laboratory .
Bone samples from the Fifth International Radiocarbon Intercomparison (VIRI) were used: VIRI-E (mammoth), -F (horse), -G (human), and -I (whale) . In this study, carbon and nitrogen content and gelatin yields were used to evaluate collagen preservation in the VIRI bone samples .
We determined the ages of five sites using the radiocarbon ( ¹⁴ C) dating method and identified animal bones sampled from three sites . The dating results show that humans occasionally occupied . . .
The collagen fraction, with the mineral portion (bioapatite) removed, is the preferred material for radiocarbon dating bone samples when preservation permits . The physically pretreated bone sample is broken into smaller particles, but not pulverized, to increase the surface area .

BONE SAMPLES FOR AMS RADIOCARBON DATING 271 FIGURE 1 Processes and isolated fractions used in radiocarbon dating of bones . Dates obtained on bulk bone samples were very often rejected in the early days of radio - carbon chronometry [17] . Inconsistency of these results with the other sample types was caused mainly by the altering effect of . . .
AMS 14C Dating of Bone from Xinzhai Site in China 25 Archaeology, Academy of Social Science of China—10 of them were bone and 10 were charcoal . Samples were organized into 5 phases for the calibration of 14C ages and the result shows that the upper limit of the Erlitou culture is about 1780-1730 BC (Qui and Cai 2001) .
