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.
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 ...
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.
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.
Prorotodactylus mirus, the type ichnospecies, has been found in the Holy Cross Mountains in Poland. It was named in 2000, with the specific name meaning "strange" in Latin in reference to unusual features in forefoot imprints. [1] [2] A second ichnospecies, P. lutevensis, was erected along with the type.
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.
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]
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]
