a. _____ Widespread, easily identified fossils that are typical of a particular time segment of the Earth’s history

Expert Solution & Answer

To determine

Pick the keyword from the given list: The name of fossils that are widespread and represent a particular time segment of earth’s history.

Answer to Problem AM

The fossils that are widespread and represent a particular time segment of earth’s history are called as the index fossils.

Explanation of Solution

Some specific fossils are used to find the similarity between the rock layers of two different localities. This process of matching the rock layers of different localities is called as correlation.

The fossils used as a base in the process of correlation are called as the index fossils. Every index fossil represent a particular time period.

Therefore, if two rocks layers obtained from different localities have same index fossils then it represents that those rock layers belong from the same time period of the history.

Conclusion:

Therefore, the word index fossils can be picked from the list.
