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]
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
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 ...
It is important to note that fossils and trace fossils such as footprints are irreplaceable resources and it is illegal to damage or remove them in national parks. ... This 8.5-mile round-trip ...
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.
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.
The oldest fossil evidence for paravians — the dinosaur group that includes the earliest birds and their closest relatives — appears around the middle of the Jurassic Period (201.3 million to ...
Chirotherium, also known as Cheirotherium (‘hand-beast’), is a Triassic trace fossil consisting of five-fingered (pentadactyle) footprints and whole tracks. These look, by coincidence, remarkably like the hands of apes and bears, with the outermost toe having evolved to extend out to the side like a thumb, although probably only functioning to provide a firmer grip in mud.
