Clastic sedimentary rocks are primarily classified on the basis of ________. grain size. What type of sediment is …Limestone is made up of fossils. After small marine animals die, their shells and skeletons build up on the ocean floor. Over time, the layers of fragments press down on each other, squeeze out the water, and recrystallize into solid rock. Sometimes the original shells, which are now fossils, are still visible.…
