This timescale remained a relative scale until the development of radiometric dating, which gave it and the stratigraphy it was based on an absolute time framework, leading to the development of chronostratigraphy one important development is the vail curve, which attempts to define a global historical sea-level curve according to inferences from worldwide stratigraphic patterns stratigraphy. Absolute dating is a method of determining the specific date of a paleontological or archaeological artifact or location based on a specific time scale or calendar scientists base absolute dating on measurable physical or chemical changes or on written records of events in the field of archeology.

Stratigraphic dating stratigraphy refers to layers of sediment, debris, rock, and other materials that form or accumulate as the result of natural processes, human activity, or both an individual layer is called a stratum multiple layers are called strata at an archaeological site, strata exposed during excavation can be used to relatively date. And the stratigraphy at the site is unclear, raising questions about whether the artifacts are as old as the soil they were embedded in — andrew lawler, science | aaas, neandertals, stone age people may have voyaged the mediterranean, 24 apr 2018.

Relative techniques in the past, relative dating methods often were the only ones available to paleoanthropologists as a result, it was difficult to chronologically compare fossils from different parts of the world however, relative methods are still very useful for relating finds from the same or nearby sites with similar geological histories. Other articles where stratigraphic correlation is discussed:and on different continents, involves stratigraphic correlation from place to place although correlation of strata over modest distances often can be accomplished by tracing particular beds from place to place, correlation over long distances and over the oceans almost.
