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]
Paleodictyon consist of thin tunnels or ridges that usually form hexagonal or polygonal-shaped honeycomb-like network. [1] Both irregular and regular nets are known throughout the stratigraphic range of Paleodictyon, but it is the striking regular honeycomb pattern of some forms such as P. carpathecum and P. nodosum which make it notable and widely studied.
In trace fossil nomenclature a Latin binomial name is used, just as in animal and plant taxonomy, with a genus and specific epithet. However, the binomial names are not linked to an organism, but rather just a trace fossil. This is due to the rarity of association between a trace fossil and a specific organism or group of organisms.
Trace fossils, also called ichnofossils, are structures preserved in sedimentary rocks that record biological activity. Wikimedia Commons has media related to Trace fossils . See also: Wikipedia:WikiProject Paleontology
Diagram showing the differences between meniscate and spreiten burrows. Modified from Chamberlain (1978). [1] Spreite (German: [ˈʃpʁaɪ̯tə] ⓘ), meaning leaf-blade in German (or spreiten (pronounced [ˈʃpʁaɪ̯tn̩] ⓘ), the plural form in German) is a stacked, curved, layered structure that is characteristic of certain trace fossils ...
Trace fossil assemblages are far from random; the range of fossils recorded in association is constrained by the environment in which the trace-making organisms dwelt. [1] Palaeontologist Adolf Seilacher pioneered the concept of ichnofacies, whereby the state of a sedimentary system at its time of deposition could be deduced by noting the trace ...
Protichnites is an ichnogenus of trace fossil consisting of the imprints made by the walking activity of certain arthropods.It consists of two rows of tracks and a medial furrow between the two rows.
Skolithos from Kraków am See, Germany. Skolithos in a bed of the Dakota Formation, New Mexico, US. Skolithos (formerly spelled Scolithus or Skolithus [1]) is a common trace fossil ichnogenus that is, or was originally, an approximately vertical cylindrical burrow with a distinct lining.
