skad [1K]

Answer:

The fossil evidence of both an ocean and a forest can be found at different depths in the same location because there might have been a presence of both an ocean and a forest at the same location at different times in the history of Earth.

Explanation:

It is clear from various studies that the Earth has had a diverse geologic history in which events like drastic climate changes, upsurging of oceans, rapid desertification, etc., have taken place many times.

Thus, the possibility of an ocean and forest having shared a single location at different times in the history of Earth cannot be neglected.
