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.
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. [1]
The taxon was named for a 60cm footprint of a bipedal ornithopod; the heel of the track is 28cm long, making it 45% of the track. This length, above that expect for an ornithopod foot, along with the width and robustness of the heel, was the distinguishing trait cited in naming the specimen as a new ichnospecies, and is the basis of the species ...
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 ...
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 ...
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.

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.
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 .
