What organism gets buried quickly?

Organisms that get buried quickly often include smaller, soft-bodied creatures like jellyfish or plankton, as well as larger organisms like fish and marine mammals in sediment-rich environments. Rapid burial typically occurs in areas with high sedimentation rates, such as river deltas or ocean floors during mass extinctions. This swift entombment helps preserve their remains, facilitating fossilization. Additionally, organisms such as plants can also be buried quickly in flood events or landslides.
