RIYADH: The Royal Commission for AlUla announced on Thursday the discovery of rare horseshoe crab fossils estimated to be 465 million years old.
Work is being carried out to study and characterize the fossils, which have not yet been scientifically classified, the RCU said in a post on X.
All of the fossils were found in an upside-down position, an unprecedented preservation pattern for this species.
The discovery was also notable in that the fossils were larger than other known species typically found from the same period.
The RCU also said that trace fossils were found, suggesting that the specimens were moving.
