"But with the ability to obtain reliable radiocarbon dates on pictographs, archaeologists have now begun to incorporate rock art into a broader study that includes other cultural remains." Archaeologists have discovered a cluster of 12 unusual stones in the back of a small, prehistoric rock-shelter near the town of Boquete in Panama.
The cache represents the earliest material evidence ...
From the captured images, researchers singled out those from stones still bearing some sort of noticeable archaeological evidence such as pigment.
The sample taken from the surface permits exclusion of the use of wood that was already old.All paintings are carefully examined on their arrival to the studio in order to understand their condition and determine the necessary treatment to be carried out.In some cases it is necessary to use various scientific techniques that can add to our understanding of the structure of the painting, its materials and the techniques of the artist."This program has algorithms predefined for working with rock art," says study leader Andres Troncoso, an archaeologist at the University of Chile."These new technologies are allowing us to account for a universe of representations that were poorly known because the conservation status of these paintings is bad," says Marcela Sepulveda, an archaeologist at the University of Tarapaca, who has done studies on rock art in northern Chile.
