* the organism must be common in rocks from most of the world
*the organism must have lived for only a geologically short period of time( a few million years to a few hundred million years)
*the organism must be easy to identify.(trilobites and ammonites are 2 kinds of organisms that are used as index fossils).

It results in fractures, joints and faults, features that you will have the ... shapes of folds, but most can be classified into three basic types. ... see shortly, plunging folds do not share this characteristic.
Well, the three ways a nation can grow are, #1. English #2. Roman #3 Oriental The order that I put them in is the order that from best, to worst, I hope that helped!
A fossil could be destroyed by heat due to melting, pressure from colliding bodies of rock, or from weathering at the surface.

Geologists use index fossils to date the rock layers they are found in and to correlate similar rock layers in different locations. Three characteristics of a good index fossil are: widespread distribution, short duration in the geologic time scale, and easily recognizable features.
An index fossil is organisms that is a signature for certain geographical eras. Index fossils are a charting of time that is used to describe other organisms found in that time era. The fossils were found in the stones that are determinations by carbon indexing and therefore are index fossils.
Relatively short rime span. To be an index fossil, a fossil organism must be easy to identify and many fossils of that organism must exist. You are using the 7th grade interactive reader...... Naughty naughty naughty

To be an index fossil, it must be widespread, commonly found (sometimes in groups) and have a short life span for which it lived. If a fossil meets all three of these requirements, it is considered an index fossil.

There are technically more than three traits and those traits are distinctive, widespread, abundant and limited in geologic time.
coal, oil, and natural gas are the three major fossil fuels :)
