“Now, a new study suggests that this proposed timeframe was off by as much as 6,000 years.”
The first estimate said 2,000 years. Chemical analysis and tool marks now put the carvings at 7,000 to 8,000. That makes them older than Stonehenge and the pyramids, and likely the oldest large animal reliefs anywhere. The first guess was off by a factor of four. Archaeology dates tend to hold until someone tests them.
