radiocarbon dating

That’s based on radiocarbon dating of the remains of grass seeds buried in the layers of sediment above and below the tracks.

Improved radiocarbon dating techniques applied to remains of short-lived plant species unearthed at archaeological sites are also producing a chronology of Polynesian colonization close to that proposed in the genetic study, Lipo says.

Hunter-gatherers have been coming to this place for around 12,000 years, according to radiocarbon dating of sediments on the cave floor.

The bones were too old for radiocarbon dating, which only works well on organic remains from the past 40,000 years or so.

The bone, just the fragment of a femur, comes from a dog that lived about 10,150 years ago, based on radiocarbon dating.

Philon went on to explain the radiocarbon dating of the book.
