Presumed human hair belonging to humans living 195,000 to 257,000 years ago was discovered in fossilized brown hyena dung, says a study.
Carnivore dung has been described to preserve mammal hair, which is probably the cause of the survival of the hair up to this day. The findings were allowed to be printed in the Journal of Archaeological Science.
