Can you date petroglyphs?
Different researchers have applied a variety of absolute dating methods directly to petroglyphs or to sediments covering them, including AMS (accelerator mass spectrometry) radiocarbon, cation ratio, amino acid racemization, OSL (optically stimulated luminescence), lichenometry, micro-erosion and micro-stratification
What are the oldest petroglyphs dated?
Winnemucca Lake is home to several petroglyphs long believed to be very old. In 2013, researchers dated the carvings to between 14,800 and 10,500 years ago. Either date would make them the oldest known petroglyphs found in North America. The carvings lie within the Pyramid Lake Indian Reservation.
How can you tell the age of a petroglyph?
Relative Dating Methods Such as which layer the artifact may have been found in, context of where it was found, what else was found with it etc. These are called relative dating methods. In determining the age of rock art relative dating methods include seriation, varnish repatination, and superimposition.
