An ichnotaxon is "a taxon based on the fossilized work of an organism", i.e. the non-human equivalent of an artifact. Ichnotaxa comes from the Greek ίχνος, ichnos meaning track and ταξις, taxis meaning ordering.
Thalassinoides is an ichnogenus of trace fossil used to refer to "dichotomously or T-branched boxworks, mazes and shafts, unlined and unornamented". Facies of Thalassinoides increased suddenly in abundance at the beginning of the Mesozoic. Such burrows are made by a number of organisms, including the sea anemone Cerianthus, Balanoglossus and fishes, but are most closely associated with decapod crustaceans of the (former) infraorder Thalassinidea.
Brutalichnus is an ichnogenus. A Case Study from the Miocene of the Czech Republic found that Brutalichnus and two other Ichnogenera have evidence of biting and gnawing traces on Reptilian and Mammalian bones. Brutalichnus contains one ichnospecies, Brutalichnusbrutalis. The ichnogenera Machichnus and Nihilichnus were described in the same paper.
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. According to modern analogues, the series of scratches represent marks of teeth of carnivorous or scavenging reptilians and mammals. Such traces are quite frequent in the fossil record since the mid-Mesozoic, but they have seldom been described in detail.
Isopodichnus is an ichnogenus of trace fossil. Ribbon-like in form, Isopodichnus traces were likely formed by the activity of an isopod crustacean foraging within the preserved sediment. Parallel to the bedding plane, a central furrow is flanked by two hypichnial ridges. Trails may also exhibit scratch marks and be associated with Rusophycus-like resting traces. Isopodichnus are very similar in form to Cruziana traces, making delineation of the two forms difficult, and controversial.
Fugichnia is an ichnogenus of trace fossil characterized as "escape burrows" that are formed as a result of organisms' attempts to escape burial in sudden high-sedimentation events like turbidity currents. The burrows are often marked with chevron patterns showing the upward direction the organisms were tunneling.
Teredolites is an ichnogenus of trace fossil, characterized by borings in substrates such as wood or amber.
Conostichus is an ichnogenus of trace fossil.
Conichnus is an ichnogenus of trace fossil.
Piscichnus is an ichnogenus of trace fossil.
Phycosiphon is an ichnogenus of trace fossil. The first recorded fossil was found in Scunthorpe, United Kingdom.
Asterosoma is an ichnogenus of trace fossil.
Komlosaurus is an ichnogenus of theropod dinosaur from the Early Jurassic of Baranya, Hungary. The type species, Komlosaurus carbonis, was described by Kordos in 1983. The type remains come from the Mecsek Coal Formation, from the Middle Hettangian to the Early Sinemurian, and comprise several footprints.
Jialingpus is an ichnogenus of dinosaur, likely a theropod. Its footprints have been found in the Feitianshan Formation, a low-energy lake formation and the holotype is SCFP-24, which was found in Late Jurassic (Oxfordian)-aged Yuechi tracksite at Huanglong, China. Its footprints were found within the vicinity of those of the smaller theropod Minisauripus, meaning that it likely hunted Minisauripus.
Camptosaurichnus is an ichnogenus of dinosaur footprint.
Dakotasaurus is an ichnogenus of dinosaur footprint.
Gregaripus is an ichnogenus of dinosaur footprint. It is possibly synonymous with Anomoepus, and may represent underprints that are instead referable to this ichnogenus.
Orcauichnites is an ichnogenus of dinosaur footprint.
Saurichnium is an ichnogenus of dinosaur footprint. Traces of different species of this genus have been found at Otjihaenamparero in central Namibia.
Tetrapodosaurus is an ichnogenus of dinosaur footprint.
