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.
