A trace fossil, also known as an ichnofossil ( / ˈɪknoʊfɒsɪl /; from Greek: ἴχνος ikhnos "trace, track"), is a fossil record of biological activity by lifeforms but not the preserved remains of the organism itself. Trace fossils contrast with body fossils, which are the fossilized remains of parts of organisms' bodies, usually ...
A fossil (from Classical Latin fossilis, lit. 'obtained by digging') [1] is any preserved remains, impression, or trace of any once-living thing from a past geological age. Examples include bones, shells, exoskeletons, stone imprints of animals or microbes, objects preserved in amber, hair, petrified wood and DNA remnants.
A fossil track or ichnite ( Greek " ιχνιον " ( ichnion) – a track, trace or footstep) is a fossilized footprint. This is a type of trace fossil. A fossil trackway is a sequence of fossil tracks left by a single organism. Over the years, many ichnites have been found, around the world, giving important clues about the behaviour (and foot ...
Treptichnus (formerly named Phycodes, Manykodes by J. Dzik, [ 2] and also known as Trichophycus[ 3]) is the preserved burrow of an animal. As such, it is regarded as the earliest widespread complex trace fossil. Its earliest appearance, around 542 million years ago (mya), [ 4] which was contemporaneous with the last of the Ediacaran biota, is ...
Certainly the animal lacked any appendages, as is evidenced by cross-cutting relationships of the trail with sedimentary structures such as ripple marks. While the identity of the trace-maker remains conjectural, Climactichnites was most likely produced by a large slug-like mollusc; modern gastropods have been observed to produce similar traces ...

Bird tracks in snow. An animal track is an imprint left behind in soil, snow, or mud, or on some other ground surface, by an animal walking across it. Animal tracks are used by hunters in tracking their prey and by naturalists to identify animals living in a given area. [1]
Prehistoric cave painting of animals at Albarracín, Teruel, Spain (rock art of the Iberian Mediterranean Basin) Cave artists use a variety of techniques such as finger tracing, modeling in clay, engravings, bas-relief sculpture, hand stencils, and paintings done in two or three colors.
