There were many skeptics. 20 years later it was carbon dated to 15,000 years. It was starting to be used as a comparison for other fossils. After another couple of decades with a new carbon dating technique it was still 15,000 years. This was fact for 20 more years, Then they carbon dated again with jaw material and it was 60 years old. It was an Orangutan jaw with the molars reworked to fit and stained to look like the skull.
