Summary:
- Researchers have discovered the well-preserved head of a prehistoric car-sized millipede, providing new insights into the evolution of these giant arthropods.
- The fossil, found in northern England, dates back to the Carboniferous period around 326 million years ago, when the Earth's atmosphere had higher oxygen levels that allowed for the existence of massive invertebrates.
- The discovery helps solve the evolutionary mystery of how these giant millipedes developed their unique head structures, which were adapted for feeding on the lush vegetation of the Carboniferous period.
