Trilobite Soft Tissue Preservation

Trilobites Family Album - Trilobite Morphology

Only rarely under very special conditions are the ventral (underside) soft tissue parts of trilobites preserved. Understanding those conditions is the field of taphonomy, the study of decaying organisms over time and how they become fossilized.
