Trilobites
If you live in an area which was covered by water in the Paleozoic Era, you might be able to find trilobite fossils. Usually, their remains become disarticulated or broken up due to the action of currents. But if the water was quiet while sediments were forming over their remains, you might find complete trilobites. Although paleontologists always like to find complete specimens, the quiet water has another advantage; tracks, grazing trails, and burrowing trails of trilobites may be preserved as well. These ichnofossils or trace fossils can tell us a lot about the walking and feeding habits of these long-extinct animals.
