Research Focus - Isotope analysis: diet, migration and climate

Migration

We undertake isotope analysis of a number of elements in bone and teeth to reconstruct the movements of hominins and fauna.  A main research focus is on the measurement of the isotopes of strontium in tooth enamel using our PIMMS facility.  We are developing the use of laser ablation as a method to sub-sample tooth enamel for strontium isotope measurements as a way to measure small-scale movements.  Additionally, we are continuing to develop the use of sulphur isotopes in bone and tooth collagen as an indicator of migrations.
