Because they can be identified to the species level and radiocarbon dated, these fossil remains are key to establishing the archaeological chronologies, palaeoenvironmental reconstructions and historical-biogeographical processes (i.e.
post-glacial recolonization events) of the last 50,000 years.
Our results show also that δ13C values of calcined bones can be used to estimate the degree of C exchange and control for postburial diagenetic alteration.
Love-hungry teenagers and archaeologists agree: dating is hard.
Therefore, its reliability for 14C dating should be seen as close to that of tooth enamel, due to crystallographic properties of calcined bones.Radiocarbon dating of the carbonate remaining in calcined bones is widely regarded as a viable alternative to date skeletal remains in situations where collagen is no longer present.However, anomalously low δ13C values measured in calcined bones prompted questions about the origin of the carbon used for dating.All the bones experienced a significant increase in IRSF values and decrease in carbonate content and δ13C values.14C ages measured in the carbonate fraction of well-calcined bones indicate that 67 ± 3% to 91 ± 8% of the carbon present in bone carbonate was replaced by carbon from the atmosphere of combustion.
