The trackway Protichnites from the Cambrian, Blackberry Hill, central Wisconsin. A trace fossil, also known as an ichnofossil (/ ˈ ɪ k n oʊ f ɒ s ɪ l /; from Greek: ἴχνος ikhnos "trace, track"), is a fossil record of biological activity by lifeforms but not the preserved remains of the organism itself.

When referring to trace fossils, the terms ichnogenus and ichnospecies parallel genus and species respectively. The most promising cases of phylogenetic classification are those in which similar trace fossils show details complex enough to deduce the makers, such as bryozoan borings , large trilobite trace fossils such as Cruziana , and ...
The ichnospecies is named in honor of Jerry MacDonald, the discoverer and local collector of the ichnofauna of the Robledo Mountains. The prints had a width of 25 mm (1 in) and consisted of symmetrical series of three to four pairs of impressions, large paddle-shaped outer tracks of 12 mm (0.5 in) in length and two or three internal linear ...
†Otozoum moodii Hitchcock, 1847 (type ichnospecies) Otozoum ("giant animal") is an extinct ichnogenus ( fossilized footprints and other markings) of sauropodomorph dinosaur from the Late Triassic - Middle Jurassic sandstones .
Ichnofauna is the diversity of fauna based on the ichnological (tracks and footprints) evidences.This term is often used by vertebrate paleontologists. [1] [2]Ichnofauna often uses parataxonomical names for tracks such as Deltapodus, Eubrontes, or Cruziana.
Limnopus is an ichnogenus of ancient tetrapod footprint.Its footprints have been found in Moscovian aged-rocks situated in Alveley, Shropshire, England, Colorado and West Virginia.
The only specimen attributed to Thinopus is a slab containing two concave impressions, a complex impression and part of a second impression. The complex impression is 84.3 millimetres (3.32 in) in length and 64 millimetres (2.5 in) in width, and has a depth of up to 9 millimetres (0.35 in).
