Explanation:

The discoveries indicates that the rocks were formed over millions of years ago due to the age of fossils they contain.

Fossils are the preserved remains of life found in rocks. Most fossils are used in relative dating of rocks.

Dinosaurs are extinct organisms that once lived in the Mesozoic. This was about 100 million years ago.
Tool man also grazed the surface of the earth just a few thousands to a million years.
