A team of international scientists, led by Prof Abderrazak El Albani, discovered well-preserved trilobite fossils from the Cambrian era in Morocco.

The fossils, found in the Tatelt Formation, are preserved in volcanic ash and showcase intricate anatomical details.

High-resolution X-ray micro-tomography revealed new features such as curved spoon-like bases on mouth appendages and a fleshy lobe called a labrum.

These findings challenge existing scientific understanding of trilobites and offer insights into their behavior and evolution.

The study, published in Science, highlights the significance of volcanic ash deposits in fossil preservation and suggests potential for further discoveries in similar settings.

The research also sheds light on trilobites' feeding habits and identifies pyroclastic deposits as valuable sites for future fossil studies.
