Although most attention in today's world focuses on dinosaurs and why they became extinct, the world of paleontology includes many other interesting organisms which tell us about Earth's past history.

The study of fossils and the exploration of what they tell scientists about past climates and environments on Earth can be an interesting study for students of all ages.

Correlation can involve matching an undated rock with a dated one at another location.

Sequencing the rock layers will show students how paleontologists use fossils to give relative dates to rock strata.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.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.
