Trace fossils are fossilized structures produced on or within a substrate by the life processes of ancient organisms, including tracks, trails, burrows, borings, and other structures. Ichnocoenosis, a suite of trace fossils representing the work of a particular benthic community, is a powerful tool for reconstructing sedimentary settings and retrieving paleoenvironmental factors.
