GEOLOGY

Detailed explanation-1: -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-2: -Trace fossils provide evidence of the activities of ancient organisms. Fossil footprints, trails, and burrows are examples of trace fossils.

Detailed explanation-3: -Burrows, coprolites, tracks, trails, nests and footprints are examples of trace fossils.

Detailed explanation-4: -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-5: -As pieces of once living things, body fossils are evidence of what was living where and when. Trace fossils are valuable because they “animate” the ancient animals or plants by recording a moment of an organism’s life when it was still alive.
