Summary

Story summary

A University of Lausanne study examines how carcass chemistry influences fossil preservation.
Aquatic animals create distinct microenvironments during decay, affecting fossilization potential.
Shrimp and snails promote reducing conditions, enhancing mineral coatings like pyrite and calcium phosphate.
Larger, protein-rich bodies lead to significant drops in oxidation-reduction potential (ORP).
Microbial succession over time further alters decay chemistry, impacting fossil outcomes.
