GENERAL GEOLOGY

Detailed explanation-1: -Ichnotaxa. Ichnotaxa (trace fossils) are fossil taxa that are based on the fossilized activities of organisms rather than the actual organisms (body fossils).

Detailed explanation-2: -Trace fossils are rocks that have preserved evidence of biological activity. They are not fossilized remains, just the traces of organisms. The imprint of an ancient leaf or footprint is a trace fossil.

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: -Fossils are classified as either body fossils or trace fossils. Body fossils were parts of the organism, such as bones or teeth. Trace fossils include foot impressions, eggs, burrows, and dung.

Detailed explanation-5: -Examples of trace fossils are tracks, trails, burrows, borings, gnawings, eggs, nests, gizzard stones, and dung. In contrast, a body fossil is direct evidence of ancient life that involves some body part of the organism.
