Dr Thalassa Matthews studies fossil micromammal (mice, rats, shrews etc.) and frog remains from archaeological and palaeontological sites. Her research includes sites dating from the Pliocene and Quaternary from the west, south and east coasts of South Africa, as well as the Cradle of Humankind (Gauteng Province), and focuses on using the microfauna from fossil sites to provide a palaeoenvironmental context for research into climate change and the development of 'modern' human behavior.
