An animal dies and falls into a river. Over time sand, rock, and other material settle on top of the animal remains, completely covering it.What type of rock might form to preserve this fossil? Lava igneous metamorphic sedimentary basaltic
Sedimentary would be your answer. Sediment is the matter that settles to the bottom of a liquid, so as rocks, dirt and mud settled over the dead body it would fossilize inside the sedimentary rock.
