I have an interest in reconstructing past environmental conditions using the stable isotope values of fossil mammalian teeth. My PhD research investigated: 1) the variability in the oxygen and carbon isotope values of rodent teeth in modern populations in Britain, 2) how the coupled isotope analysis of rodent teeth and mollusc shells can be used to quantify Quaternary palaeotemperatures, 3) short-term climatic changes recorded by the oxygen isotope values of rodent teeth from cave sequences, and 4) variations in the carbon isotopes values of rodent teeth during the Late Quaternary.

The stable oxygen isotope values (δ¹⁸O) of small mammal teeth can potentially provide important palaeoclimate records for Quaternary sequences, due to the abundance of these remains in various depositional environments. However, the application of this proxy to Quaternary climate reconstructions has hitherto been limited, due to 1) uncertainties in...
The oxygen isotope analysis of rodent teeth has the potential to provide important quantitative records of terrestrial climatic change. Grimes et al. (2003) proposed a novel approach to utilizing this technique for palaeotemperature reconstruction, involving coupling the δ18O values of rodent teeth with that of other coeval biominerals (e.g. mollus...
The aim of this project is to investigate the reliability of using oxygen isotopes in mammal teeth as a palaeoclimate proxy by: 1) establishing a modern relationship between oxygen isotopes in mammalian dental carbonate and the oxygen isotope composition of local meteoric water, and 2) applying this modern relationship to the reconstruction of past temperatures and climatic variability during Pleistocene interglacial and interstadial stages in the UK.
