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. [ 1 ] [ 2 ] These footprints are commonly found in Europe , and have also been identified in North America and Morocco .
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.
The most promising cases of phylogenetic classification are those in which similar trace fossils show details complex enough to deduce the makers, such as bryozoan borings, large trilobite trace fossils such as Cruziana, and vertebrate footprints. However, most trace fossils lack sufficiently complex details to allow such classification.
The only specimen attributed to Thinopus is a slab containing two concave impressions, a complex impression and part of a second impression. The complex impression is 84.3 millimetres (3.32 in) in length and 64 millimetres (2.5 in) in width, and has a depth of up to 9 millimetres (0.35 in).
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] Some ichnospecies have both types (e.g ...
Argoides is an ichnogenus of dinosaur footprint, originally named as an ichnospecies of Ornithichnites, [1] [2] left by what was possibly an ornithopod, although due to the age of the tracks (some of which predate the oldest known ornithopod fossils), they were probably instead made by theropods. [3]
Parabrontopodus is an ichnogenus of dinosaur footprint, that was initially described by Lockley et al. in 1994, [1] and was assigned to Sauropoda by Lockley in 2002 and in 2004 by Niedzwiedzki and Pienkowski. Various species through their footprints that are characterized by the association of two impressions left by hand and foot.
