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 ...
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.

Ornithichnites is an ichnotaxon of mammal footprint that was originally classified as a dinosaur. [1] The name was originally used by Edward Hitchcock in 1836 as a higher group name rather than a specific ichnogenus, [1] and thus the name does not have priority over specific ichnogeneric names even if they were first identified as Ornithichnites.
The study of such fossils is known as ichnology and the footprints may be given scientific names (ichnospecies). Grallator is one example of an ichnogenus based on ichnites. Strictly speaking, an ichnospecies is the name of the trace fossil, not of the animal that made it.
Charles Gilmore described the Paleocene amphibian tracks from the Fort Union Formation of Montana. He named the new ichnospecies Ammobatrachus montanensis for the tracks. He observed that these were the first Paleocene fossil footprints to be documented in the scientific literature. [18] Potential Paleocene mammal footprints were reported from ...
An ichnospecies of dinosaur footprint from the Early Cretaceous of Gulin County, Sichuan, China was discovered and named as Eubrontes nobitai. The epithet of scientific name commemorate Nobita Nobi , a fictional character in the Doraemon series, for the movies Doraemon: Nobita's Dinosaur and Doraemon: Nobita's New Dinosaur , which have inspired ...
Chelichnus is an ichnogenus of Permian tetrapod footprint. The name means tortoise traces , because the shape of the prints was originally mistakenly thought to be produced by a tortoise. [ 1 ] This is now known to be incorrect, as tortoises did not evolve until much later.
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 .
