Dating the fossil record activity
The method of reading the order is called stratigraphy (layers of rock are called strata).Relative dating does not provide actual numerical dates for the rocks.The oldes tknown fossils are The magnetic north pole has changed throughout the history of Earth and its geographical coordinates are known in different geological eras.Some minerals have magnetic properties and are directed towards the north magnetic pole when in aqueous suspension, for example clays.That fossil species may have been dated somewhere else, so you can match them and say that your fossil has a similar age.Some of the most useful fossils for dating purposes are very small ones.When subjected to external stimuli, mineral emits light due to these changes.This luminescence is weak and distinct as apply heat (TL), visible light (OSL) or infrared (IRSL).

Geologists have studied the order in which fossils appeared and disappeared through time and rocks. Fossils can help to match rocks of the same age, even when you find those rocks a long way apart.
Fossils are important for working out the relative ages of sedimentary rocks.
