Answer:

Hope this helps!! :D

Explanation:

Often, the rock layers bookending the mass extinction are noticeably different in their compositions. These changes in the rocks show the effects of environmental disturbances that triggered the mass extinction and sometimes hint at the catastrophic cause of the extinction.

You can often tell by disturbances in the fossils bones. Maybe like dust or particles symbolize harm or mass extinction in a prehistoric animal or maybe even new fossils like some animals that went extinct recently like 200 years.
