New parameters for the characterization of diagenetic alterations and heat-induced changes of fossil bone mineral using Fourier transform infrared spectrometry
Abstract Diagenetic alteration may limit the potential use of the biogenic composition of fossil bone as a reliable source of information for dietary, environmental and climatic reconstructions. OneExpand

Variability of bone preservation in a confined environment: The case of the catacomb of Sts Peter and Marcellinus (Rome, Italy)
Most of the studies investigating the diagenetic trajectory of fossil bones focus on open-air sites and very little work have been published in confined environments such as catacombs. While theExpand

Radiocarbon Dating of Calcined Bones: Insights from Combustion Experiments Under Natural Conditions
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,Expand

Rapid Quantification of Bone Collagen Content by ATR-FTIR Spectroscopy
Expensive and time-consuming preparation procedures for radiocarbon and stable isotope analyses can be conducted on archaeological bone samples even if no collagen is preserved. Such unsuccessfulExpand

Screening in situ bone and teeth preservation by ATR-FTIR mapping
Abstract Bones and teeth are highly hierarchically structured and hererogeneous materials, and post mortem processes can reinforce this heterogeneity. It is therefore important to consider thisExpand

Direct Dating and Physico-Chemical Analyses Cast Doubts on the Coexistence of Humans and Dwarf Hippos in Cyprus
In the Mediterranean, the island dwarf megafaunas became extinct around the end of the Pleistocene, during a period of rapid and global climate change. In Cyprus, this coincided with the first humanExpand
