Answer

Brief Explanations:

Good index fossils have a broad geographic distribution so they can be found in many locations for correlation. They are short - lived to represent a narrow time interval. And they are easy to identify at the species level for accurate dating. Being an invertebrate is not a necessary characteristic for an index fossil.

Answer:

had a broad geographic distribution, short - lived, easy to identify at the species level
