Detailed explanation-1: -Fossils may also consist of the marks left behind by the organism while it was alive, such as animal tracks or feces (coprolites). These types of fossil are called trace fossils or ichnofossils, as opposed to body fossils. Some fossils are biochemical and are called chemofossils or biosignatures.

Detailed explanation-2: -Ichnofossils, also known as trace fossils, are geological records of the activities and behaviors of past life. Some examples include rock evidence of nests, burrows, footprints, and scat. These fossils are different from body fossils that preserve the actual remains of a body such as shells or bones.

Detailed explanation-3: -The four types of trace fossils are tracks and trails (footprints), burrows and bores (worm holes), gastroliths (stomach stones), and coprolites (fossilized feces).

Detailed explanation-4: -A trace fossil is a result of animal activity. For example, a dinosaur footprint or an arthropod burrow would be an example of a trace fossil. The holes in this petrified wood are burrows made by beetles before fossilization.

Detailed explanation-5: -1. Name five kinds of trace fossils. Burrows, coprolites, tracks, trails, nests and footprints are examples of trace fossils.
