Which is not a factor in a fossil organism being useful as an index fossil?
it must have lived through a long span of time
What 3 requirements do index fossils have?
Index fossils must be widespread geographically, have a short stratigraphic range, and be easily identifiable. These characteristics make them useful for determining the relative ages of rock layers and correlating them across different locations.
What are some index fossil characteristics?
It must be distinct from other organisms. It must have lived in a very wide geographic region
Is it true that To be a useful index fossil a species must have been rare?
No, an index fossil does not have to have been rare to be useful. The key characteristic of an index fossil is that it is easily recognizable, widespread geographically, and existed for a relatively short period of time. This allows geologists to use it to help date the rock layers in which it is found.
