Trilobites are thought to have been a marine organism because the fossils are found in rocks that contain other salt-water animals. Trilobites are thought to be one of the earliest groups of arthropods.
If the rock is sedimentary in origin and if it has a repeating organized pattern or resembles a shell or other organism that is alive today it may be a fossil. There are numerous books in stores or libraries with pictures of fossil organisms that you can compare with your finds.
The first way is if they can produce viable offspring (which must also be able to reproduce). If one of the organisms is extinct, they compare bone structures, whether it has similar vestigial parts as the other organism. I believe another way is by the comparison of some enzymes.
