Peruvian Textile Remnants Confirm Occupation at Least 12,000 Years Ago

Past Horizons has an excellent presentation on the recent dating of textile remnants recovered from the Guitarrero Cave high in the Andes Mountains 30 years ago!  Although other artifacts also recovered from the cave dated to about 12,000 years ago, it wasn't certain how old, exactly, the textile remnants were.  Now - applying the newest tecnological advances in dating delicate objects - we have an answer.

“By dating the textiles themselves, we were able to confirm their antiquity and refine the timing of the early occupation of the Andes highlands,” Jolie said. His team used the latest radiocarbon dating technique—accelerated mass spectrometry—to place the textiles at between 12,100 and 11,080 years old.

You can see from the woven fabric remnants the "checkerboard" pattern innate within the ancient weave technique.
