Researchers Discover Trilobite Fossils from 515 Million Years Ago in Morocco
Researchers from the French University of Poitiers have uncovered two new species of trilobites in Morocco. The ancient arthropods were found exceptionally well-preserved in their final postures within layers of volcanic ash at Ait Youb in the Souss Massa region.
Trilobites are extinct marine arthropods that lived over 500 million years ago. The scientific team led by Professor Abderrazak El Albani emphasized the significant role of underwater volcanic ash deposits in fossil preservation.
El Albani stated, This discovery demonstrates for the first time the crucial role of underwater deposits of volcanic ash in the preservation of fossils and the importance of exploring volcanic underwater environments.
The finding sheds light on an ecosystem dating back 515 million years, with the use of high-resolution X-ray micro-computed tomography offering detailed insights into the fossilized trilobites.
The researchers highlighted the significance of pyroclastic deposits in capturing and safeguarding biological remnants, showcasing the intricate details of these ancient life forms. The study revealed new insights into the anatomical organization of trilobites, settling a century-long debate about the presence of a labrum in these fossil arthropods.
The discovery underscores the importance of protecting the Ait Youb site and considering its registration in the UNESCO World Heritage listing. Trilobites remain among the most recognizable invertebrate fossils, and this new finding opens doors to further understanding Earth’s history.
The unveiling of these well-preserved trilobite fossils showcases the wealth of knowledge that lies beneath the surface in Morocco, highlighting the country’s rich paleontological heritage.
