A geologist shows you a rock and says it was taken from

a layer of the Grand Canyon that contained anamal fossils.

You can ask the geologist one question about the fossils

found in the layer from which the rock was taken, and

then you must tell the geologist whether the rock was

found above or below the Great Unconformity. What

question should you ask and how will it help you?

I know nothing about geology, so i just did a search for "Great Unconformity" and was taken to the first page. It had this to say. "it divides rocks with familiar fossils from those with no fossils or only fossil bacteria."

From this line and the OP I would not have to ask any questions if the rock was indeed found with animal fossils it came from above. Because below is only fossil bacteria or no fossils.

I would ask "What type of fossilized ramains were found?" If he answers with anything other than a single celled organism then it must have come from above the Great Unconformity. I am pretty sure of this but if I am not please let me know. Thanks.

Still trying to figure out how to post an answer. This is attempt number 2.
