The ichnogenus Thalassinoides: burrow fossil produced by crustaceans from the Middle Jurassic, HaMakhtesh HaKatan, 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]
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.
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.
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.
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 .

Ceratopsipes goldenensis is an ichnospecies of dinosaur footprint, described in 1995 from the Laramie Formation in Colorado. [1] It is represented by massive pes prints approaching 80 centimetres (31 in) in width.
