Along the way, we'll learn how stratigraphic succession and radioactive decay contribute to the work of paleontologists.

Consider the following scenario: Paul the Paleontologist is a very famous scientist who has studied dinosaur bones all over the world.

He concluded, after studying rocks at many outcrops, that each layer represented a specific interval of geologic time.

Further, he proposed that wherever un-contorted layers were exposed, the bottom layer was deposited first and was, therefore, the oldest layer exposed; each succeeding layer, up to the topmost one, was progressively younger.

It only sequences the age of things or determines if something is older or younger than other things.

Some types of relative dating techniques include climate chronology, dendrochronology, ice core sampling, stratigraphy, and seriation.

However, relative methods are , which is that if there are layers of deposits, those laid down first will be on the bottom and those laid down last will be on the top. However, geological strata are not always found to be in a neat chronological order.

Wind and water erode strata and some areas are uplifted or even tilted.

However, we must be careful to note whether or not the fossil comes from the mixed strata zone of the filled in hole..Free 5-day trial Discover how geologists study the layers in sedimentary rock to establish relative age.Learn how inclusions and unconformities can tell us stories about the geologic past.But really, how do scientists figure out how old their dinosaur bones are?And, what about other findings like fossil fish, plants and insects?Geologists establish the age of rocks in two ways: numerical dating and relative dating.
