Ichnotaxon comes from the Ancient Greek ἴχνος (íchnos) meaning "track" and English taxon, itself derived from Ancient Greek τάξις (táxis) meaning "ordering". [ 1 ] Ichnotaxa are names used to identify and distinguish morphologically distinctive ichnofossils , more commonly known as trace fossils ( fossil records of lifeforms ...
Grallator ["GRA-luh-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.
†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 .
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.

Ichniotherium (meaning "marking creature") is an ichnogenus of tetrapod footprints from between the Late Carboniferous period to the Early Permian period attributed to diadectomorph track-makers. [ 1 ] [ 2 ] These footprints are commonly found in Europe , and have also been identified in North America and Morocco .
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 ...
Argoides is an ichnogenus of dinosaur footprint, originally named as an ichnospecies of Ornithichnites, [1] [2] left by what was possibly an ornithopod, although due to the age of the tracks (some of which predate the oldest known ornithopod fossils), they were probably instead made by theropods. [3]
Abelichnus is an extinct ichnogenus of dinosaur footprint from the Candeleros Formation and the Rio Limay Formation. The type ichnospecies, Abelichnus astigerrae, was first discovered in Argentina in 1987 and was recorded as the biggest known dinosaur footprint ever discovered. [1] Abelichnus probably grew to a size of 12.5-13 meters (41-42 ft ...
