What fossils tell us about crocodiles

8th April 2024

66 million years ago, the impact of a meteorite with the Earth shook up marine and continental environments, leading to the mass extinction of animal and plant species. The highly adaptable Sebecosuchians, part of the crocodilian order, are among the lineages that survived. A team from the Laboratoire de Géologie de Lyon has used several approaches, such as chemical analysis of bones and detailed study of their skulls, to characterize their diet and the environment in which these ancient species evolved.

This research was financed in whole or in part by the French National Research Agency under the ANR SEBEK – AAPG2019 project. This report was produced and financed as part of the “Sciences avec et pour la société – Culture scientifique technique et industrielle” (SAPS) call for projects.
