They are engaged in defining the stages of hominid evolution and their artifactual record, and the assignment of a chronology to these stages.Chronology is the science of measuring time and ordering of the things in time.b) Absolute These methods are based on calculating the date of artefacts in a more precise way using different attributes of materials.This method includes carbon dating and thermoluminescence.In fact, chronology is one of the most fundamental issues in and perhaps a characteristic of archaeology.Archaeologists use several methods to assign ages to events of the past.Most of the summarized dating methods may not be used with regularity in the field, but individuals should be informed about their existence, usefulness, and sample collection methods.Bibliography & Glossary (PDF) Class Outline The Candidate Application and Record of Previous Experience forms.

Archaeologists have access to various techniques for dating archaeological sites or the objects found on those sites.But while the difficulties of single life may be intractable, the challenge of determining the age of prehistoric artifacts and fossils is greatly aided by measuring certain radioactive isotopes.Until this century, relative dating was the only technique for identifying the age of a truly ancient object.Radiocarbon dating involves determining the age of an ancient fossil or specimen by measuring its carbon-14 content.Carbon-14, or radiocarbon, is a naturally occurring radioactive isotope that forms when cosmic rays in the upper atmosphere strike nitrogen molecules, which then oxidize to become carbon dioxide. This is an informational tour in which students gain a basic understanding of geologic time, the evidence for events in Earth’s history, relative and absolute dating techniques, and the significance of the Geologic Time Scale.
