What amino acids in shells can tell us about Bronze Age people

A new study has shed new light on the use of mollusc shells as personal adornments by Bronze Age people. The research team used amino acid racemisation analysis (a technique used previously mainly for dating artefacts), light microscopy, scanning electron microscopy and Raman spectroscopy, to identify the raw materials used to make beads in a complex necklace discovered at an Early Bronze Age burial site at Great Cornard in Suffolk, UK.
