C) Underwater organisms in dry land

Explanation:

The listed options are:

A) Large number different-sized footprints.

B) Plant but no animal fossils.

C) Underwater organisms in dry land.

D) Straight teeth buried below curved teeth.

Discovering fossils of underwater organisms in dry land demonstrates that thousands to millions of years ago, there was a body of water such as an ocean, lake, or river in an area that is now dry land. This gives important insights into what was the Earth's climate at that epoch and how it has changed throughout time.

This discovery could allow researchers to study what the conditions were at that time and why that body of water dried out. Moreover, it could lead to answers of the reasons behind the extinctions or evolution of some underwater organisms.
