Radiocarbon dating of ancient rock paintings
Intriguingly, analysis of the animal bones revealed bears lived in the cave until 33,000 years ago ‘contemporary with the first human occupation phase.’ However, the study added: ‘It is important to remember that a minimum of 200 individual cave bear skeletons have been identified thus far.
— A new dating method finally is allowing archaeologists to incorporate rock paintings — some of the most mysterious and personalized remnants of ancient cultures — into the tapestry of evidence used to study life in prehistoric times. Rowe points out that rock paintings, or pictographs, are among the most difficult archaeological artifacts to date.
Las fechas obtenidas tienen un promedio entre 110–140 años de más antiguedad que lasfechas calendricas.
Hay diverses posibilidades que expliican esta discrepancia, la primera es aplicable a todas lasfechas de radiocarbono en carbon; la segunda, es aplicable apinturas rupestres y la tercera, es especifica para el trópico.
Caution is urged in the interpretation of dates on charcoal pigments from rock paintings; consideration of the “old wood” and “old charcoal” factors is important.
Several possible reasons are discussed for this discrepancy: one that is applicable to all radiocarbon dates on charcoal, one that applies to rock paintings, and one that is specific for the tropics.The cave features a number of human handprints as well.Researchers were confused after their studies revealed the intricate order in which the cave paintings were made, showing that both animals and humans lived in the cave in the distant past.It validates the method and allows rock painting to join bones, pottery and other artifacts that tell secrets of ancient societies, Rowe said.Radiocarbon age determinations are presented on three hieroglyphic texts from Naj Tunich cave in Guatemala containing Maya calendar dates.
