Preliminary investigation by paleontologists of the age of a particular stone artifact or rock begins with a thorough examination of the location-site together with a study of the geological record.In order to confirm that the object is contemporaneous with the soil or sedimentary deposit in which it was found, and not a later intrusive burial in an older deposit, comparisons with other fossils, rocks and rock strata are made to establish the site's biostratigraphy.Once contemporaneity has been established the age of the object can be assessed, sometimes quite precisely, using techniques of "absolute" or chronological dating.A major type of absolute dating is radiometric dating.For a sculptural masterpiece from the late Neolithic of southern Europe, see the terracotta sculpture known as The Thinker of Cernavoda (c.5000 BCE, National Museum of Romanian History, Bucharest).Noted for its metallurgy, including exquisite early bronze, gold and silver metalwork, and ceramics.Nearby hand stencils were dated to about 37,000 BCE.
