The ichnogenus Thalassinoides: burrow fossil produced by crustaceans from the Middle Jurassic, Makhtesh Qatan, 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 ichnospecies is named in honor of Jerry MacDonald, the discoverer and local collector of the ichnofauna of the Robledo Mountains. The prints had a width of 25 mm (1 in) and consisted of symmetrical series of three to four pairs of impressions, large paddle-shaped outer tracks of 12 mm (0.5 in) in length and two or three internal linear ...
Breviparopus (ichnotype B. taghbaloutensis) is the name given to an ichnogenus of dinosaur, having been made by an unknown genus of sauropod.As an ichnogenus, the taxon is represented by (and named for) a 90-metre (295 ft) long series of fossil tracks, or ichnites, found in the spring of 1979 in the Atlas Mountains of present-day Morocco.
The confusing history of dinosaur footprints means many kinds of theropod tracks have been put into the Megalosauripus ichnogenus, [4] even though they were an entirely different ichnospecies. This makes it hard to piece together what exactly is Megalosauripus , and what is not.
Prorotodactylus mirus, the type ichnospecies, has been found in the Holy Cross Mountains in Poland. It was named in 2000, with the specific name meaning "strange" in Latin in reference to unusual features in forefoot imprints. [2] [3] A second ichnospecies, P. lutevensis, was erected along with the type.
†Otozoum moodii Hitchcock, 1847 (type ichnospecies) Otozoum ("giant animal") is an extinct ichnogenus ( fossilized footprints and other markings) of sauropodomorph dinosaur from the Late Triassic - Middle Jurassic sandstones .
Planolites is an ichnogenus found throughout the Ediacaran and the Phanerozoic that is made during the feeding process of worm-like animals.The traces are generally small, 1–5 mm (0.039–0.197 in), unlined, and rarely branched, with fill that differs from the host rock.
Bonaparteichnium is a dinosaur ichnogenus known from the Candeleros Formation of Neuquén Province, Argentina.It was named by Jorge O. Calvo in a 1991 paper, alongside the other ornithopod ichnogenera Sousaichnium and Limayichnus.
