Scientists are always spouting information about the ages of rocks and fossils. Well, they figure it out using two different methods: relative dating and numerical dating.
Let's find out more about these geological dating methods in order to understand how Paul the Paleontologist can be so sure about the age of his dinosaur fossils.
If I told you that I was 30 years old, that number would be my numerical age.
If I told you I was 32 years younger than my mother, that number would be my relative age.
Recently, he appeared on the evening news to talk about a new dinosaur he just discovered. Paul says he can tell from the fossils that superus awesomus lived on Earth about 175 million years ago.
Paul is super awesome, so I'm going to take him at his word.
He could be pretty confident that his super awesome dinosaur was about 175 million years old.
He saw that it underwent radioactive decay, or emission of energetic particles to produce new elements.
The most common form of relative dating is called stratigraphic succession.
This is just a fancy term for the way rock layers are built up and changed by geologic processes.
But really, how do scientists figure out how old their dinosaur bones are?
And, what about other findings like fossil fish, plants and insects?
