Summary

In this conference, geologist Jean-Jacques Bahain presents the main dating methods used in prehistory. He begins by emphasizing the importance of chronology in archaeology and paleoanthropology, illustrating with recent discoveries. He then introduces the four main families of dating methods: naturalistic (stratigraphy, biostratigraphy, paleomagnetism), chemical (amino acid racemization, obsidian hydration), radioactive (carbon-14, potassium-argon, uranium-thorium, cosmogenic nuclides), and methods based on radiation damage (ESR, TL). He details the principles, applications, and limitations of each method, using concrete examples such as the dating of Toumaï, Lucy, and the Tautavel Man. He stresses the importance of stratigraphic context and the need to choose the appropriate method according to the material and the age range. The conference concludes with a discussion on the complementarity of methods and the need for a multidisciplinary approach.
