We will also provide some background on our list of invertebrate animals examples. A fossil (from Classical Latin: fossilis, literally "obtained by digging") is any preserved remains, impression, or trace of any once-living thing from a past geological age.Examples include bones, shells, exoskeletons, stone imprints of animals or microbes, objects preserved in amber, hair, petrified wood, oil, coal, and DNA remnants. The New Jersey fossil record provides us with examples from four of the seven classes. Examples of parasitic invertebrates: These include helminth parasites, ectoparasites (leech), lice, etc. The cases of trace fossils in tufa (i.e., cool to near ambient freshwater carbonate deposit with common macrophyte and invertebrate remains; Ford and Pedley, 1996), in addition to those mentioned under microbial/caddisfly mounds, are rare.
