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]
When referring to trace fossils, the terms ichnogenus and ichnospecies parallel genus and species respectively. 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 ...
Grallator (GRA-lə-tor) is an ichnogenus (form taxon based on footprints) which covers a common type of small, three-toed print made by a variety of bipedal theropod dinosaurs.
Strictly speaking, an ichnospecies is the name of the trace fossil, not of the animal that made it. An international team's discovery of a set of 1.5 million-year-old human ancestor footprints in Ileret, Kenya provides the earliest direct evidence of a modern human style of upright walking.
Protochirotherium, also known as Protocheirotherium (‘first hand-beast’), is a Late Permian?- Early Triassic ichnotaxon (trace fossil) consisting of five-fingered (pentadactyl) footprints and whole tracks, discovered in Germany and later Morocco, Poland and possibly also Italy.
Otozoum ("giant animal") is an extinct ichnogenus (fossilized footprints and other markings) of sauropodomorph dinosaur from the Late Triassic-Middle Jurassic sandstones. ...
Chelichnus is an ichnogenus of Permian tetrapod footprint. The name means tortoise traces , because the shape of the prints was originally mistakenly thought to be produced by a tortoise. [ 1 ] This is now known to be incorrect, as tortoises did not evolve until much later.
