Saudi Arabia finds 465-million-year-old horseshoe crab fossils in AlUla, revealing ancient marine behavior.
Saudi Arabia has unearthed 465-million-year-old horseshoe crab fossils in AlUla’s AlGharameel Nature Reserve, among the oldest ever found.
Preserved upside down with signs of attempted reorientation, the fossils offer rare insights into ancient marine behavior.
Geological evidence points to a shallow, storm-prone coastal environment that aided rapid burial and exceptional preservation.
The discovery, detailed in a peer-reviewed study in Gondwana Research, marks a significant contribution to understanding early arthropod evolution and reinforces AlUla’s status as a key site for paleontological research.
