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 ...
[3] [1] Three ichnospecies of Ichniotherium have been proposed as valid: I. cotta, I. sphaerodactylum, and I. praesidentis. [ 1 ] In a 2007 study, the diadectid species Diadectes absitus was determined to be the track-maker associated with I. cotta tracks, and the related diadectid species Orobates pabsti was linked to I. praesidentis based on ...
The ichnogenus Thalassinoides: burrow fossil produced by crustaceans from the Middle Jurassic, HaMakhtesh HaKatan, southern Israel. An ichnotaxon (plural ichnotaxa) is "a taxon based on the fossilized work of an organism", i.e. the non-human equivalent of an artifact.
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.

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 ...
Rotundichnus is an ichnogenus of dinosaur footprint. The ichnospecies Rotundichnus muchehagensis dates to the early lower Cretaceous in central Laurasia (present-day Germany) and the largest footprint, that was 87 cm (2.85 ft) long, belongs to an individual that measured 21.5 meters (70.5 ft) and weighed 36.5 tonnes (40.2 short tons).
Parabrontopodus is an ichnogenus of dinosaur footprint, that was initially described by Lockley et al. in 1994, [1] and was assigned to Sauropoda by Lockley in 2002 and in 2004 by Niedzwiedzki and Pienkowski. Various species through their footprints that are characterized by the association of two impressions left by hand and foot.
