Answer

Explanation:

Step1: Observe layer - to - layer correspondence

By comparing the fossil layers in North America and Europe, we can see that the layer structure has a certain correspondence. Layer D in Europe corresponds to layer 2 in North America.

Step2: Use given dating information

We know that the fossil in European layer D is dated to 500 million years ago. Since layer D in Europe corresponds to layer 2 in North America, the fossil in North American layer 2 is also likely to be 500 million years old.

Answer:

D. 500 million years ago
