Exceptionally Preserved Trilobite Fossils Unveil Unseen Anatomy

Volcanic ash in Morocco reveals 3D details of trilobites' soft tissues, offering new insights into their biology and evolution.

The fossils, over 500 million years old, were found in the High Atlas of Morocco.
These trilobites were preserved in volcanic ash, similar to the preservation seen in Pompeii.
CT scans revealed previously unseen anatomical features, including digestive systems and mouthparts.
The discovery challenges previous assumptions about trilobite anatomy and feeding mechanisms.
Researchers suggest volcanic ash deposits could be a valuable source for finding exceptionally preserved fossils.
