  2. Ichnotaxon - Wikipedia

    en.wikipedia.org/wiki/Ichnotaxon

    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.

  3. Ichniotherium - Wikipedia

    en.wikipedia.org/wiki/Ichniotherium

    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 .

  4. Trace fossil - Wikipedia

    en.wikipedia.org/wiki/Trace_fossil

    The trackway Protichnites from the Cambrian, Blackberry Hill, central Wisconsin. A trace fossil, also known as an ichnofossil (/ ˈ ɪ k n oʊ f ɒ s ɪ l /; from Greek: ἴχνος ikhnos "trace, track"), is a fossil record of biological activity by lifeforms but not the preserved remains of the organism itself. [1]

  5. Trace fossil classification - Wikipedia

    en.wikipedia.org/wiki/Trace_fossil_classification

    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.

  6. Grallator - Wikipedia

    en.wikipedia.org/wiki/Grallator

    Grallator ["GRA-luh-tor"] is an ichnogenus (form taxon based on footprints) which covers a common type of small, three-toed print made by a variety of bipedal theropod dinosaurs. Grallator-type footprints have been found in formations dating from the Early Triassic through to the early Cretaceous periods.

  7. Megalosauripus - Wikipedia

    en.wikipedia.org/wiki/Megalosauripus

    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.

  8. Diplocraterion - Wikipedia

    en.wikipedia.org/wiki/Diplocraterion

    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]

  9. Ceratopsipes - Wikipedia

    en.wikipedia.org/wiki/Ceratopsipes

    Ceratopsipes goldenensis is an ichnospecies of dinosaur footprint, described in 1995 from the Laramie Formation in Colorado. [1] It is represented by massive pes prints approaching 80 centimetres (31 in) in width.
