OBJECTIVES. • Define, compare, and contrast relative and absolute age dating. relative age of geologic events. Explain how absolute dating has established numerical ages for geologic events is usually found by combining clues from. Second, it is possible to determine the numerical age for fossils or earth materials . Relative dating to determine the age of rocks and fossils .. Combined observations of this type have led to the development of the geomagnetic polarity time.
Paul is super awesome, so I'm going to take him at his word.
But really, how do scientists figure out how old their dinosaur bones are? And, what about other findings like fossil fish, plants and insects? Scientists are always spouting information about the ages of rocks and fossils. How do they know these ages? Well, they figure it out using two different methods: 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.
Relative Dating The first method that scientists use to determine the age of rocks is relative dating. In this method, scientists compare different layers of rock to determine an ordered sequence of events in geologic history. That means they don't really know how old their rocks actually are. The key in relative dating is to find an ordered sequence. Scientists piece together a story of how one event came before or after another. Relative dating cannot tell us the actual age of a rock; it can only tell us whether one rock is older or younger than another.
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.
Combining numerical and relative age dating - Relative and numerical age dating
Scientists know that the layers they see in sedimentary rock were built up in a certain order, from bottom to top. When they find a section of rock that has a lot of different strata, they can assume that the bottom-most layer is the oldest and the top-most layer is the youngest.
Again, this doesn't tell them exactly how old the layers are, but it does give them an idea of the ordered sequence of events that occurred over the history of that geologic formation. Fossil succession can be used to determine the relative ages of fossils. Sort of an offshoot of stratigraphic succession is fossil succession, or a method in which scientists compare fossils in different rock strata to determine the relative ages of each.
Let's say that Paul the Paleontologist found an iguanodon fossil in the light green layer shown above. And, he also found a coelophysis fossil in the yellow layer.
