Dating can be done by radiocarbon dating or other techniques which look at the amounts of elements like iron or potassium. It is the assumed that the tool is approximately as old as the rock which surrounds it.
To establish the age of a rock or a fossil, researchers use some type of clock to determine the date it was formed. Geologists commonly use radiometric dating methods, based on the natural radioactive decay of certain elements such as potassium and carbon, as reliable clocks to date ancient events.
How do archaeologists date stone structures?
Archaeologists use that assumption, called the law of superposition, to help determine a relative chronology for the site itself. Then, they use contextual clues and absolute dating techniques to help point to the age of the artifacts found in each layer.
How is stone carbon dated?
Geologists do not use carbon-based radiometric dating to determine the age of rocks. Carbon dating only works for objects that are younger than about 50,000 years, and most rocks of interest are older than that. Over time, carbon-14 decays radioactively and turns into nitrogen.

Which period in history is known as the Stone Age?
The Stone Age began about 2.6 million years ago, when researchers found the earliest evidence of humans using stone tools, and lasted until about 3,300 B.C. when the Bronze Age began. It is typically broken into three distinct periods: the Paleolithic Period, Mesolithic Period and Neolithic Period.
