WebA fossil is preserved remains or traces of living things. 2. They form in sedimentary rock. 3. Fossils form when a living thing dies and is buried by sediment which hardens into rock preserving the shape of the organism. Identify different kinds of fossils. Compare and contrast molds and casts. 1. Trace fossils are formed by organisms performing the functions of their everyday life, such as walking, crawling, burrowing, boring, or feeding. Tetrapod footprints, worm trails and the burrows made by clams and arthropods are all trace fossils. See more A trace fossil, also known as an ichnofossil , is a fossil record of biological activity but not the preserved remains of the plant or animal itself.

Webremains, determine if they are body or trace fossils, and identify the type of fossil preservation for the body fossils. 2. Review what the students will be recording on Part 2 of their data collection sheets. 3. Recording Data. Students should identify whether the fossil is a body fossil or trace fossil.
