Exempel på hur man kan använda ICHNOTAXON i en mening

• However, in 1994 the ichnotaxon Tyrannosauropus were identified as large plant-eater dinosaur tracks, and when combined with analyses to distinguish three-toed carnivore and herbivore dinosaur footprints the large tracks attributed to Tyrannosauropus at Lark Quarry were interpreted as being produced by a large herbivore similar to Muttaburrasaurus, rather than by a predatory theropod, and were suggested to belong to the ichnogenus Amblydactylus instead.
• He originally assigned them to ichnotaxon Ornithichnites in 1836, then Ornithoidichnites in 1841, before coining Eubrontes in 1845.
• The fossils on which this ichnotaxon was based are now thought to be from giant myriapods, such as Arthropleura.
• Fossil sauropod tracks, belonging to an unknown ichnotaxon, and stegosaur tracks belonging to the ichnogenus and species Garbina roeorum have been reported from the formation since the 1990s.
• Nevertheless, the authors considered the survival of stegosaurians into the Maastrichtian to be possible, noting the presence of the stegosaurian ichnotaxon Deltapodus in the Maastrichtian Lameta Formation (western India).
• Griesbachian aged layers of the formation also preserve an unexpectedly diverse ichnotaxon assemblage, including the ichnogenera Catenichnus, Helminthopsis, Lockeia, Palaeophycus, Planolites, Rhizocorallium, Spongeliomorpha, Taenidium and Thalassinoides.
• Protochirotherium is the earliest known chirotheriid ichnotaxon, similar to later forms such as Chirotherium, Isochirotherium, and Brachychirotherium.
• Duffin, Lauer & Lauer (2022) describe chimaeroid egg cases from the Upper Jurassic (Tithonian) Altmühltal Formation (Germany), probably produced by Ischyodus quenstedti, and name a new ichnotaxon Chimaerotheca schernfeldensis.
• It should not be used indiscriminately, particularly with ichnotaxons, where the fact that an ichnotaxon derives part of its morphology from taphonomic processes may not always render it an invalid ichnotaxon.
