Preserved- forms when entire organisms or parts of organisms are prevented from decaying by being trapped in rock, ice, tar, or amber. Relative and absolute ages are used together and mutually constrain each other, particularly in areas of complex geology where both absolute and relative ages of events can be ambiguous. Gliffy Diagram Venn Diagram of Relative and Absolute Dating. In other words, how old the fossil is how long ago it was made. Radiometric dating is the fossils are most recent than rocks or absolute implies an object.

Petrified permineralized - forms when minerals soak into the buried remains, and changing them into rock. By comparing evidence from orbit, as use dating uses observation of artefacts. The half- life is the amount of time it takes for half of those elements to turn into another element known as the parent element. Index Fossil- fossil of an organism that existed for only a short period of geologic time and lived in many place.
