Free 5-day trial You may already know how to date a fossil with a rock.But did you know that we can also date a rock with a fossil?However, the assumption of contemporaneity may not always be correct.This is due to the fact that one or both of the objects may have been moved or redeposited into a different location.Sequencing the rock layers will show students how paleontologists use fossils to give relative dates to rock strata.
However, we must be careful to note whether or not the fossil comes from the mixed strata zone of the filled in hole..
When a scientist finds a section of rock that has lots of different strata, he assumes that the bottom-most layer is the oldest, and the top-most layer is the youngest.
But sometimes, a scientist finds a couple of rock outcrops that are separated by a wide distance.
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.
Teaching about Earth's history is a challenge for all teachers.
