    Treptichnus. 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 ...

  3. Trace fossil - Wikipedia

    en.wikipedia.org/wiki/Trace_fossil

    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 ...

    en.wikipedia.org/wiki/Fossil

    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.

  5. Fossil track - Wikipedia

    en.wikipedia.org/wiki/Fossil_track

    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 ...

  7. Ediacaran biota - Wikipedia

    en.wikipedia.org/wiki/Ediacaran_biota

    The Ediacaran (/ ˌiːdiˈækərən /; formerly Vendian) biota is a taxonomic period classification that consists of all life forms that were present on Earth during the Ediacaran Period (c. 635–538.8 Mya). These were enigmatic tubular and frond-shaped, mostly sessile, organisms. [1][2] Trace fossils of these organisms have been found ...

  8. Trace fossil classification - Wikipedia

    en.wikipedia.org/wiki/Trace_fossil_classification

    Trace fossil classification. Trace fossils are classified in various ways for different purposes. Traces can be classified taxonomically (by morphology), ethologically (by behavior), and toponomically, that is, according to their relationship to the surrounding sedimentary layers. Except in the rare cases where the original maker of a trace ...

  9. Coprolite - Wikipedia

    en.wikipedia.org/wiki/Coprolite

    A coprolite (also known as a coprolith) is fossilized feces. Coprolites are classified as trace fossils as opposed to body fossils, as they give evidence for the animal's behaviour (in this case, diet) rather than morphology. The name is derived from the Greek words κόπρος (kopros, meaning "dung") and λίθος (lithos, meaning "stone").
