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 ...
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 .
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.

Special conditions are required, in order to preserve a footprint made in soft ground (such as an alluvial plain or a formative sedimentary deposit). A possible scenario is a sea or lake shore that became dried out to a firm mud in hot, dry conditions, received the footprints (because it would only have been partially hardened and the animal ...
†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 .
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 ...
A new analysis of three-toed fossil footprints that date back more than 210 million years reveals that they were created by bipedal reptiles with feet like a bird’s.
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.
