Radiocarbon dating of rock
What could be the oldest images in the world have been discovered in France.
And the engravings of mammoths and wild cows known as aurochs were made from individual pixels – essentially the same technique used to produce images on computers and televisions.
For example, based on the primate fossil record, scientists know that living primates evolved from fossil primates and that this evolutionary history took tens of millions of years.
By comparing fossils of different primate species, scientists can examine how features changed and how primates evolved through time.
The age of the fossil must be determined so it can be compared to other fossil species from the same time period.
Understanding the ages of related fossil species helps scientists piece together the evolutionary history of a group of organisms.
The idea behind radiocarbon dating is straightforward, but years of work were required to develop the technique to the point where accurate dates could be obtained.The pictures are also being compared to the pointillism technique supposedly pioneered in the 1880s by artists like Vincent van Gogh and Georges Seurat.The 16 decorated stone blocks were discovered during an excavation of a now-collapsed rock overhang in France’s Vézère Valley, which was used as a shelter by the Aurignacian people, the earliest modern human culture in Europe. The method was developed by Willard Libby in the late 1940s and soon became a standard tool for archaeologists.Libby received the Nobel Prize in Chemistry for his work in 1960.
