A student finds a cast fossil of a fish and concludes that the fossil must be made of sedimentary rock. What evidence best supports the student’s conclusion?
A. Only marine fossils form in sedimentary rock.
B. Sedimentary rocks are different colors and fish bones will fossilize well in this type of rock.
C.Nearly all fossils form in sedimentary rock.
D. Fish fossils only form on the shore in sedimentary rocks.
Almost all fossils are in sedimentary rocks due to the lower pressures required to form these stones. Sedimentary rocks are built by layering materials over long periods of time, which can incase bones, creating fossils.
