Review Rocks-10

This layer of rock contains fossilized tracks from a dinosaur (Dilophosaurus). The black object is my cell phone for size reference. What kind of rock is it?

  1. Igneous

    No. Igneous rocks formed from magma or lava. An igneous rock would not have fossilized dinosaur tracks.
  2. Sedimentary

    Yes! Sedimentary rocks are deposited by wind, water, ice, or gravity, and they often contain fossils. The presence of fossils is one of the indications that a rock is probably sedimentary.
  3. Metamorphic

    No. Metamorphic rocks have been changed by heat and pressure from a different kind of rock. The metamorphic process would have destroyed the tracks.
  4. It is not rock.

    No. These dinosaur tracks are in rock.
