Researchers discovered well-preserved trilobite fossils in Moroccan volcanic ash, providing insights into their soft internal structures after centuries of limited understanding.
Volcanic ash's fine texture allowed for precise impressions of trilobites' anatomical features, enhancing scientists' ability to study these ancient arthropods in detail.
The discovery suggests that a brief volcanic event rapidly entombed the trilobites in ash, preserving even minute details like the sediment-packed digestive tract of one specimen.
