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.
Ichniotherium (meaning "marking creature") is an ichnogenus of tetrapod footprints from between the Late Carboniferous period to the Early Permian period attributed to diadectomorph track-makers.
Sketch by Richter (1926) showing spreite in a Diplocraterion parallelum burrow.. Diplocraterion is an ichnogenus describing vertical U-shaped burrows having a spreite (weblike construction) between the two limbs of the U. [1] [2] The spreite of an individual Diplocraterion trace can be either protrusive (between the paired tubes) or retrusive (below the paired tubes). [3]
Megalosauripus is an ichnogenus that has been attributed to dinosaurs.The first ever appearance of this ichnospecies is 201 - 197 million years ago during the Early Jurassic period. [2]
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.
†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.
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.
