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. [1]
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 vertebrate footprints. However, most trace fossils lack sufficiently complex details to allow such classification.
Characichnos (meaning "score trace") is an ichnogenus of possibly dinosaurian tetrapod footprint. It includes a single species, C. tridactylus, known from prints found in the Middle Jurassic Saltwick Formation of Yorkshire, United Kingdom. [1]
Name of the Footprint The name Megalosauripus means large saurian footprints and derives historically from an archaic and generalized concept of megalosaurid dinosaurs. The name may coincidentally, but by no means certainly, imply a relationship to dinosaurs like Megalosaurus and its relatives.
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.

Otozoum ("giant animal") is an extinct ichnogenus (fossilized footprints and other markings) of sauropodomorph dinosaur from the Late Triassic-Middle Jurassic sandstones. Footprints were made by heavy, bipedal or, sometimes, quadrupedal animals with a short stride that walked on four toes directed forward. [ 1 ]
