Trace fossil
Trace fossils are those details preserved in rocks that are indirect evidence of life. While we are most familiar with relatively spectacular fossil hard part remains such as shells and bones, trace fossils are often less dramatic, but nonetheless very important. Trace fossils include burrows, track marks, coprolites (fossilized feces), stromatolites (fossilized algal mounds), and rhizoliths or rhizocretions (fossil remains of roots).
