Detailed explanation-1: -Trace fossils are marks left by an animal or plant that has made an impression. These fossils include nests, burrows, footprints or any other markings of the animal’s time on the earth. The structure of the animal or plant remains as a mineral form.
Detailed explanation-2: -Trace fossils include footprints, trails, burrows, feeding marks, and resting marks. Trace fossils provide information about the organism that is not revealed by body fossils. Trace fossils are formed when an organism makes a mark in mud or sand. The sediment dries and hardens.
Detailed explanation-3: -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-4: -Different types of trace fossils include track, burrow, boring, trails etc. Trail is a type of trace fossils in which continuous impression of animal movement is preserved in cohesive sediments like mud. These continuous impressions are preserved in geological record and are known as trail ichnofossil.
Detailed explanation-5: -Burrows, coprolites, tracks, trails, nests and footprints are examples of trace fossils.
