Summary Introduction
To review:
A scenario illustrating the use of Ediacaran fossils as index fossils.
Introduction:
An index fossil is a preserved rock record that is characteristic of a particular time. It is the fossil, which is useful for dating the strata. A fossil must be distinctive or specific, easily found, and sufficient with wide distribution geographically to be an index fossil. These are helpful in marking the boundaries according to the geologic time scale.
