Here is a list of the top 10 oldest works of Prehistoric art created during the Stone Age.It features all the major types of Paleolithic art yet discovered, including: petroglyphs (the oldest type of cultural expression), parietal art (like cave painting, as well as hand stencils and other abstract signs) and also mobiliary art (like ivory carving and other portable forms of sculpture).As we pointed out in these two articles, radiometric dates are based on known rates of radioactivity, a phenomenon that is rooted in fundamental laws of physics and follows simple mathematical formulas.Dating schemes based on rates of radioactivity have been refined and scrutinized for several decades.Despite this, the momentum gained in the two decades prior to 1972 has made 4.5 b.y.a popularly accepted “universal constant” even though the foundations on which it was based have been virtually removed.A fossil can be studied to determine what kind of organism it represents, how the organism lived, and how it was preserved.However, by itself a fossil has little meaning unless it is placed within some context.

At present, a large variety of fossils, tools and artifacts are being studied by paleoanthropologists and other Stone Age scholars, in order to fix their date of origin.

Despite seeming like a relatively stable place, the Earth's surface has changed dramatically over the past 4.6 billion years.

Mountains have been built and eroded, continents and oceans have moved great distances, and the Earth has fluctuated from being extremely cold and almost completely covered with ice to being very warm and ice-free.

These changes typically occur so slowly that they are barely detectable over the span of a human life, yet even at this instant, the Earth's surface is moving and changing.

As these changes have occurred, organisms have evolved, and remnants of some have been preserved as fossils.
