Evolutionary success of theropod dinosaur-like crocodiles
The biological crisis at the end of the Cretaceous, 66 million years ago, affected marine and continental environments on a global scale.
Crocodilians are emblematic because they survived, thanks to their particular physiology and adaptations to the aquatic environment. Another group of crocodilians, the Sébécosuchia, appear to be purely terrestrial, and their survival in this crisis calls into question the influence of abiotic factors on biodiversity. Sébécosuchiens are indeed interpreted as morphological analogues of non-avian theropod dinosaurs; but why did Sébécosuchiens survive when these dinosaurs disappeared? This report was produced and funded as part of the "Sciences Avec et Pour la Société" (SAPS) call for projects.
