ASAP
Assessing the Amplitudes of Seasonality
in Continental Archaeological and Paleontological Contexts
Principal investigators
- Olga OTERO, Pi (PALEVOPRIM)
Main collaborators
- Géraldine GARCIA (PALEVOPRIM)
- Antoine SOURON (PACEA)
- Doris BARBONI (CEREGE)
Type of project
ASAP is a research project granted by Région Nouvelle Aquitaine (2019-2023)
Research questions
ASAP aims the development, the calibration and the validation of two independent methods for the quantification of changes in the intensity of seasonal contrasts in the past. It is notably based on the study of growth marks recorded in the bone remains of ecthoterm animal fossils, and on the analysis of functional associations in fossil assemblages.
