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]
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.
Skolithos trace fossil (scale bar is 10 mm) A number of biologically-created sedimentary structures exist, called trace fossils. Examples include burrows and various expressions of bioturbation. Ichnofacies are groups of trace fossils that together help give information on the depositional environment. In general, as deeper (into the sediment ...
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 ...

Trace macrofossils are fossilized evidence of animal behavior. These may include tracks, burrows and dung . [11] Trace fossils are the primary type of fossils used by paleontologist to reconstruct extinct animal behaviors. The study of these fossils is called Ichnology. [12]
Scientists in Argentina have discovered excellently preserved fossil remains of the oldest-known tadpole, the larval stage of a large frog species that lived alongside dinosaurs about 161 million ...
Fodinichnia / ˌ f ɒ d ɪ ˈ n ɪ k n i ə / (singular fodinichnion) are trace fossils formed by deposit feeders as they excavate the sediment in search of food. [1] They tend to have repeated patterns (e.g. Chondrites) or spreites (e.g. Rhizocorallium), the shape reflecting the systematic feeding strategy used by the organism as it scours the sediment.
