The Principle of Paleontological Identity is the theory that the layers of sedimentary rocks around the world can be dated by the fossils which they contain. Based on this theory, two layers having the same fossils are regarded as having the same age. This principle is based on the existence of stratigraphic fossils. It is taken in theory to make it possible to correlate sedimentary sequences in distant areas from each other.
Fossils have been found nearly everywhere in the world because animals die everywhere in the world. Although most fossils that have been fond will have only been a part of it/.

The Principle of Superposition argues that rock layers towards the top are younger than those at the bottom. This was the principal technique used in the early days.Fossils have discontinuities - a group will appear, and after a time will vanish again. But very similar fossils appear around the world at the same time.This subject paleontology, has good records, and a newly found fossil can usually be identified by comparison with the paleontological record.Today of course, radiometric dating is used very widely to determine the age of both rocks themselves, and of fossils. These techniques use the half-life of radioactive elements to determine the age.
Application protocol layers that are specific to certain applications such as the World Wide Web (WWW), email, and FTP causes websites to appear on the computer screen.
There are an unlimited number of times that any word appears in the world. Certain words appear a certain number of times in a certain piece of literature.

You dig for fossils where there is a brown X on the ground.
In the main fossils are tirtouga and archen but after you got the national dex, you can go to the dream world and get fossils of ominite etc.
Younger layers are deposited on top of older layers, whether the layer is sedimentary or volcanic. Occasionally faults may result in overthrusts, where a series of older layers may be pushed over the top of younger layers. But this is rare. In general, the older layers will be the lower layers.
