Abstract

Oxygen isotopes

Enamel

Mammal

Miocene

Aquitaine

Palaeoclimate

The relationship between the oxygen isotope ratio of mammal tooth enamel and that of drinking water was used to reconstruct changes in the Miocene oxygen isotope ratio of rainfall (meteoric water δ18OMW). These, in turn, are related to climatic parameters (temperature, precipitation and evaporation rate). δ18O values of rhinocerotid teeth from the Aquitaine Basin (southwestern France) suggest a significant climatic change between 17 and 12 Ma, characterized by cooling together with precipitation increase, in agreement with other terrestrial and oceanic records.
