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.
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.
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]
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.
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.
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.
It was first described from bite traces in 2006. The ichnogenus originally contained two ichnospecies, Nihilichnus nihilicus and Nihilichnus mortalis. The ichnogenera Brutalichnus and Machichnus were described in the same paper. [3]
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.
