Use the evidence of these ammonite index fossils, what can we say about these two geologic layers?

They were laid down around the same time

Sandstone is older than the shale

Shale is older than the sandstone

Since they are from different locations, unless we can radiometric Lee date them, we cannot distinguish anything between the two

Since they are from different locations, unless we can radiometric Lee date them, we cannot distinguish anything between the two

Explanation:

It is not possible to determine information about the geological layers of different locations just by viewing the images, as the question above asks. This is because these two sites have different natural elements that acted on these layers and these fossils differently. In this case, making conclusions only with the visualization of the images, would not promote accurate and correct information. Ideally, a radiometric dating would be performed in both cases, so that accurate conclusions could be created.
