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.
Experts believe that the footprint was most likely left by a dinosaur (grallator) that stood about 75 centimeters (29.5 inches) tall and 2.5 meters (about 8 feet) long and walked on its two hind feet. [11] [12] The scientists called the girl's discovery "the finest impression of a 215 million-year-old dinosaur print found in Britain in a decade ...
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 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.

†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 .
Farlowichnus is an ichnogenus of small theropod dinosaur footprint. It includes a single species, F. rapidus, known from prints found in the Early Cretaceous Botucatu Formation of Brazil. Farlowichnus is known from several fossil trackways that indicate that it was likely a cursorial animal that was well-adapted to desert environments. [1]
Bellatoripes (Latin for "warlike foot") is an ichnogenus of footprint produced by a large theropod dinosaur so far known only from the Late Cretaceous of Alberta and British Columbia in Canada. The tracks are large and three-toed, and based on their size are believed to have been made by tyrannosaurids , such as Albertosaurus and Daspletosaurus .
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).
