Absolute dating of fossils definition
The Wheeler Formation has been previously dated to approximately 507 million year old, so we know the trilobite is also about 507 million years old.
As the name implies, relative dating can tell which of the two artifacts is older.
We talked about relative dating of rocks and how scientists use stratigraphic succession to compare the ages of different rock layers.
You should already understand that the lower rock strata are generally older than the strata found higher up in the rock.
Different methods have their own limitations, especially with regard to the age range they can measure and the substances they can date.
A common problem with any dating method is that a sample may be contaminated with older or younger material and give a false age.
