Question

Trilobites lived 200-500 million years ago. If the paleontologists finds a fossil of a trilobite in a layer of sandstone, what does that tell the paleontologist about the age of the sandstone?

Answer 1

This is easy it tells you that the sand stone is 200 to 500 million years old hope this helped pleas make brainyleist

Answer 2

If a fossil was found inside a layer of the sandstone, we can infer that the fossil is younger than the sandstone.

The fossil is younger than the sandstone because:

• The sandstone must have been there first for the fossil to be on it
• After the Trilobite died, it then got fossilized in the sandstone which was already there.

The sandstone must therefore be older than the fossil because the fossil would not be on the layer of the sandstone had the sandstone not being there first.

In conclusion, the fossil is younger than the sandstone.
