Suppose you are hiking in the hills and you come across a wall of rock. you look closely at the rock and you notice a trilobite fossil embedded in it. what might this fossil suggest yo you about the hills you are hiking in? a. the hills used to be volcanic and are now dormant b. the hills, at one time, were under water c. the hills were once at a much higher elevation d. the hills are rich in sandstone

Your answer would be B). The hills, at one time, were under water. Trilobite fossils are fossils that are rocks that have bones engraved in them. Trilobites are marine animals that have been extinct for thousand of years. Since they're marine animals, the hill use to have water. You wouldn't see a Trilobite fossil in a land where there has been no source of water.
