Trace fossils contrast with body fossils, which are the fossilized remains of parts of organisms' bodies, usually altered by later chemical activity or by mineralization. The study of such trace fossils is ichnology - the work of ichnologists. [2] Trace fossils may consist of physical impressions made on or in the substrate by an organism. [3]
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.
Coprolites are classified as trace fossils as opposed to body fossils, as they give evidence for the animal's behaviour (in this case, diet) rather than morphology. The name is derived from the Greek words κόπρος (kopros, meaning "dung") and λίθος (lithos, meaning "stone"). They were first described by William Buckland in 1829.
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.
Due to the chaotic nature of trace fossil classification, several ichnogenera hold names normally affiliated with animal body fossils or plant fossils. For example, many ichnogenera are named with the suffix -phycus due to misidentification as algae. [2] Edward Hitchcock was the first to use the now common -ichnus suffix in 1858, with ...

A fossil track or ichnite (Greek "ιχνιον" (ichnion) – a track, trace or footstep) is a fossilized footprint. This is a type of trace fossil. A fossil trackway is a sequence of fossil tracks left by a single organism. Over the years, many ichnites have been found, around the world, giving important clues about the behaviour (and foot ...
Even when fossils that are found in paleosols are understood, much more can be learned regarding their preservation, ecology, and evolution by studying the paleosols they inhabited. Fossil stumps in a paleosol. A fossilized footprint, burrow, or coprolite (fossil feces), are examples of trace fossils (ichnofossils). These trace fossils do not ...
