Question

Which of these is MOST LIKELY to be a reason for why an animal or plant fossilizes?

A. It was buried slowly.
B. It was exposed to bacteria.
C. It died in a wet or warm environment.
D. It died in an oxygen-poor environment.

Answer 1

D.

Step-by-step explanation:

Animals cannot live without oxygen, so no animals live there. In these situations, the only possibility of fossilization is if a fish or other swimming animal dies in oxygen-rich waters above, sinks down into the stagnant muddy bottom, and is buried by sediments.
