This fossil was discovered in the desert. What is the BEST argument that proves the fish lived in the desert?

• The fossil does not prove that fish lived in this area. The earth's crust shifts over many years and the fossil could have ended up in the desert because of the shifting.

• After the Ice Age, melting water carried the fossil into what is now the desert. This area was a desert long ago just as it is a desert now. Climates do not change.

• Fossils are very old and take thousands of years to form. Long ago this area must have had a river or been an ocean that dried up years ago.

• People that lived long ago used tools to draw this organism into the rock. It is not a fossil because fish do not live in the desert.
