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.
Dromopus is a reptilian ichnogenus commonly found in assemblages of ichnofossils dating to the late Pennsylvanian (Moscovian stage) to the late Permian (Changhsingian stage). It has been found throughout Europe, as well as in the United States, Canada, and Morocco.
Dromaeosauriformipes represents one of the few known fossil records of Early Cretaceous dromaeosaurids in South Korea, along with the indeterminate dromaeosaurid femur from the Gugyedong Formation and two ichnospecies of Dromaeosauripus, D. hamanensis from the Haman Formation and D. jinjuensis from the Jinju Formation.

Ornithichnites is an ichnotaxon of mammal footprint that was originally classified as a dinosaur. [1] The name was originally used by Edward Hitchcock in 1836 as a higher group name rather than a specific ichnogenus, [1] and thus the name does not have priority over specific ichnogeneric names even if they were first identified as Ornithichnites.
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 ...
Machichnus is an ichnogenus.It was erected by Mikuláš et al. (2006) for shallow, thin, discrete, parallel to subparallel, smooth-bottomed scratches, occurring on bone tissue in small groups or series.
Chelonipus is a trace fossil ichnogenus attributed to turtles and testudines. [1] Chelonipus ichnospecies are known from the a number of locations including the Early Triassic of Wyoming and Utah, [1] Late Jurassic Morrison Formation [citation needed], the Late Paleocene-Early Eocene Chuckanut Formation, and the Eocene of Texas.
The foot impressions show five digits and clear palm prints, though the fifth digit is not always impressed. The digits are short and broad with rounded tips.
