The extinction of great apes in Eurasia: environmental context revealed by ungulate teeth

MerceronPrior to the radiation of hominines that took place in Africa, the Eurasian continent was home to a radiation of great apes during the Miocene. All of these hominids went extinct at the end of the Miocene (between 9 Ma and 7 Ma), at least in western Eurasia. Gildas Merceron investigates the potential changes in climate and vegetation at both continental and local scales contemporaneous to this extinction. This presentation will depict how the dental remains of the antelopes, deers, and horses, which lived before and after the extinction of European great apes, can be used to track these changes. The past vegetation and its changes through time and space are explored using a combination of carbon stable isotope analyses on tooth enamel and dental microwear analysis. These two approaches decipher the chemical and physical properties of the plants ingested by these ungulates. Besides, by measuring the oxygen isotope compositions in tooth enamel, some aspects of the climatic conditions, especially seasonality, can be pictured before and after the extinction of great apes in Europe.
