Missions

The goal of the PACé project is to characterize by a geochemical approach the paleoclimate, the paleo-environment and the food web of the Early Cretaceous continental ecosystem of Angeac-Charente.
The project will rely mainly on the analyses of stable isotope compositions of carbon (13C/12C), oxygen (18O/16O), sulphur (34S/32S), calcium (44Ca/42Ca) and strontium (87Sr/86Sr) recorded in the bone tissues of some 30 vertebrates and fossilized plants of the Angeac-Charente deposit.
This project is carried out as part of the DIM " Heritage and Ancient Materials" and is part of the research themes of UMR7207/CR2P and UMR8212/LSCE.

Activities

Interdisciplinary Paleontology/Geochemistry project consisting in a geochemical approach whose results will have to be compared with the sedimentological, paleobiological and taphonomic data already obtained.
Reasoned sampling in existing collections and in the field will have to be carried out. Analyses of the isotopic composition of carbon from fossilized wood will be carried out on the Paris Saclay Geoscience analytical platform (PANOPLY), those of oxygen, carbon, sulfur, calcium and strontium of vertebrate apatite will be carried out at the Lyon Geology Laboratory (GISEL platform and HR-MC-ICPMS facility at the ENS).

Skills

- Ph.D. in paleontology/geochemistry with good experience in isotope analyses.
- Good knowledge of Mesozoic continental ecosystems.
- Fluency in English.
- Mobility.
- Good teamwork skills and autonomy expected.

Work Context

The postdoctoral researcher (M/F) will be mainly based at the National Museum of Natural History, but the work will be carried out within 3 research centres:
- PDM team (20 members) of CR2P/UMR7207. This team focuses on the evolution of biodiversity in time and space. It is interested in the study of organisms in their taxonomic, paleobiogeographic and ecological context.
- GLACIOS team (20 members) of the LSCE/UMR8212. The team seeks to establish an absolute chronological framework within which to situate key events in Earth's history and human evolution, and to describe and interpret the geochemical processes governing the present and past environments. Access to the analytical platform (PANOPLY).
- LGL-TPE/UMR5276 Paleoenvironment and Paleobiodiversity team. The team is interested in the reconstruction of Mesozoic terrestrial paleoenvironments and vertebrate ecology. The team will allow the access to the analytical platform (GISEL).

Constraints and risks

Travel in France (Angoulême and Lyon).
