Classify each of the following as either relative or absolute fossil dating.
Relative Dating; One fossil is found to be older than another fossil.
Absolute Dating; Age of a fossil is found to be 61.1 million years old.
How to classify fossils?Relative dating is defined as the age of a rock layer (or the fossils it contains) compared to other layers. This dating can be gotten by looking at the position of rock layers. Whereas, absolute dating is the numeric age(specific age) of a layer of rocks or fossils. Absolute age can be determined by using radiometric dating.
1. Relative Dating; One fossil is found to be older than another fossil.
This is because In an excavation of a project area, if we see a set of fossils found 5 meters down, they will be younger than fossils found 17 meters down.
2. Absolute Dating; Age of a fossil is found to be 61.1 million years old.
A fossil analyzed with radiometric dating would have undergone maybe 2 half lives of radioactive isotope.
