The ichnogenus Thalassinoides: burrow fossil produced by crustaceans from the Middle Jurassic, Makhtesh Qatan, 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.
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 ...
Dromopus is a reptilian ichnogenus commonly found in assemblages of ichnofossils dating to the late Pennsylvanian (Moscovian stage) to the late Permian (Changhsingian stage). It has been found throughout Europe, as well as in the United States, Canada, and Morocco.
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.

Grallator (GRA-lə-tor) is an ichnogenus (form taxon based on footprints) which covers a common type of small, three-toed print made by a variety of bipedal theropod dinosaurs.
Five invertebrate traces including a new ichnospecies of Diplichnites (Diplichnites rawi), were described from the latest Carboniferous of Shropshire, England by Hedge et al. (2019) [20] Tetrapod burrow most likely produced by a notosuchian crocodylomorph is described from the Upper Cretaceous Bauru Group by Martinelli et al. (2019). [21]
The trackmaker of Haenamichnus is probably a large azhdarchid pterosaur, likely reaching 10 m (33 ft) in wingspan, 3 m (9.8 ft) in height and 145 kg (320 lb) in body mass, more than ten times heavier than the Kori bustard.
Bonaparteichnium is a dinosaur ichnogenus known from the Candeleros Formation of Neuquén Province, Argentina.It was named by Jorge O. Calvo in a 1991 paper, alongside the other ornithopod ichnogenera Sousaichnium and Limayichnus.
