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.
[3] [1] Three ichnospecies of Ichniotherium have been proposed as valid: I. cotta, I. sphaerodactylum, and I. praesidentis. [ 1 ] In a 2007 study, the diadectid species Diadectes absitus was determined to be the track-maker associated with I. cotta tracks, and the related diadectid species Orobates pabsti was linked to I. praesidentis based on ...
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 ...
Anticheiropus is an ichnogenus of dinosaur footprint belonging to a saurischian. [1] It has only been discovered in Massachusetts (Portland Formation, Newark Supergroup).Two ichnospecies are known (both are known from a single footprint): [2] [3] A. hamatus and A. pilulatus, both discovered around 1863 and named by Edward Hitchcock in 1865.
Rotundichnus is an ichnogenus of dinosaur footprint. The ichnospecies Rotundichnus muchehagensis dates to the early lower Cretaceous in central Laurasia (present-day Germany) and the largest footprint, that was 87 cm (2.85 ft) long, belongs to an individual that measured 21.5 meters (70.5 ft) and weighed 36.5 tonnes (40.2 short tons).
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.

Limnopus is an ichnogenus of ancient tetrapod footprint.Its footprints have been found in Moscovian aged-rocks situated in Alveley, Shropshire, England, Colorado and West Virginia.
Sketch by Richter (1926) showing spreite in a Diplocraterion parallelum burrow.. Diplocraterion is an ichnogenus describing vertical U-shaped burrows having a spreite (weblike construction) between the two limbs of the U. [1] [2] The spreite of an individual Diplocraterion trace can be either protrusive (between the paired tubes) or retrusive (below the paired tubes). [3]
