Why fossils are found almost exclusively in sediment and sedimentary rocks. Fossils come in many types. An incredible multitude of organisms lived prior to the species that we see on to date to between 542 and 556 Ma, putting them just before the Cambrian Trilobites are iconic Paleozoic fossils; they were more.
