What is Sandstone - Its Rock Type, Color, Uses, and Worth

 · Sandstone Fossils. One of the most wonderful phenomenon in the rock and mineral world is the capturing of fossils within sedimentary rock. Fish fossils, snails, corrals, clams, and other life can be trapped in sedimentary rock such as sandstone. Some sandstone's will contain fossils, but typically most fossils are found in limestone.
