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.

There are actually ten principals used by paleontologists to do relative dating. They are:The Principal of UniformitarianismThe Principal of Intrusive relationshipsThe Principal of Cross-cutting relationshipsThe Principal of Inclusions and componentsThe Principal of HorizontalityThe Principal of SuperpositionThe Principal of Faunal successionThe Principal of Lateral continuityThe Principal of Inclusions of Igneous rocksandThe Principal of Included fragments
"its basically when someone has a personalitydisorder or an identity disorder..at least that's what i read about" This is completely incorrect. What you are talking about is DID (Dissociative Identity Disorder) Identity Diffusion is part of the identity crisis that all teenagers go through. It is a theory by James Marcia. Identity Diffusion is when the individual does not care to find their own identity.
