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.
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.
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]
[3] [1] Three ichnospecies of Ichniotherium have been proposed as valid: I. cotta, I. sphaerodactylum, and I. praesidentis. [ 1 ] In a 2007 study, the diadectid species Diadectes absitus was determined to be the track-maker associated with I. cotta tracks, and the related diadectid species Orobates pabsti was linked to I. praesidentis based on ...
When referring to trace fossils, the terms ichnogenus and ichnospecies parallel genus and species respectively. 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 ...
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.
Hyloidichnus is a reptile ichnogenus commonly found in assemblages of ichnofossils dating to the Permian [1] to Triassic [2] in North America, [1] Africa, [2] [3] South America, [4] and Europe.
The ichnospecies is named in honor of Jerry MacDonald, the discoverer and local collector of the ichnofauna of the Robledo Mountains. The prints had a width of 25 mm (1 in) and consisted of symmetrical series of three to four pairs of impressions, large paddle-shaped outer tracks of 12 mm (0.5 in) in length and two or three internal linear ...
