Electron backscatter diffraction (EBSD) originated in materials science and has transferred to biomineral research providing insight into fossil and modern biominerals. An electron microscopy technique, EBSD requires a fine polished sample surface where the electron beam diffracts in the first few lattice layers, identifying mineral, polymorph and crystallographic orientation. The technique is ...

ABSTRACT In the last decade, identification of bone fragments by peptide mass fingerprinting or zooarchaeology spectrometry is developing as a powerful tool in Quaternary palaeontology. The sequence amino acids that make up collagen molecule shows slight variations between taxa, which can be studied for taxonomic purposes. This requires reference databases allow identification. Although cave be...
