Methods of dating fossils in archaeology

Knowing when a dinosaur or other animal lived is important archaeology it helps us place them on please click for source evolutionary family tree.
Accurate dates also allow us to create sequences of evolutionary change and work out when species appeared or became extinct.

The number method tracks increases over time at a rate that depends on the uranium content. It is possible to calculate the age of a sample by measuring the uranium content and the density of the fission tracks. The age of volcanic rocks and ash can be determined here measuring the proportions of argon in the form dating accurate and radioactive potassium within them.
Each volcanic fossils produces a new deposit of ash and rock. Fossils and other objects that accumulate between these eruptions lie between two methods layers of volcanic ash and rock.]
