The previously uncovered camel image was discovered by Eudald Guillamet, a well-known restorative specialist from Andorra, who was invited by the State Office of Protection of Cultural Heritage of Bashkiria to clean the cave of graffiti.
The images in the Kapova are remarkable for their use of red pigment and the caves are characterized by partially blurred shapes, partly the remains of erased drawings, and partially traces of Paleolithic artistic activities of unknown origin.
Play a game that tests your ability to match the percentage of the dating element that remains to the age of the object.
The simplest form of isotopic age computation involves substituting three measurements into an equation of four variables, and solving for the fourth.
It is filled with representations of stone-age fauna such as the wooly rhino, bison, horse, and, of course, the wooly mammoth itself.In addition, it requires that these measurements be taken from several different objects which all formed at the same time from a common pool of materials.(Rocks which include several different minerals are excellent for this.) Each group of measurements is plotted as a data point on a graph.In many cases, there are independent cues (such as geologic setting or the chemistry of the specimen) which can suggest that such assumptions are entirely reasonable.However, the methods must be used with care -- and one should be cautious about investing much confidence in the resulting age...
The equation is the one which describes radioactive decay: If one of these assumptions has been violated, the simple computation above yields an incorrect age.
