carbon-14 dating

Using carbon-14 dating techniques, researchers confirmed the ages of the tombs, the artifacts, and the writing.

The researchers studied the raw materials and technology and carried out carbon-14 dating, which revealed that the set dates to the early and middle Holocene period, between 9,500 and 6,200 years ago.

In addition, carbon-14 dating of twelve remains has indicated three periods of funerary use in the cave: in 3800 BC, in 2500 BC.

The archaeologists used a process known as carbon-14 dating to find out how old the bone instruments were.

Not only are megafauna bones relatively rare there, but carbon-14 dating could only show that the animals had been gone at least 40,000 years.
