A trace fossil, also known as an ichnofossil ( / ˈɪknoʊfɒsɪl /; from Greek: ἴχνος ikhnos "trace, track"), is a fossil record of biological activity by lifeforms but not the preserved remains of the organism itself. Trace fossils contrast with body fossils, which are the fossilized remains of parts of organisms' bodies, usually ...
Trace fossils are classified in various ways for different purposes. Traces can be classified taxonomically (by morphology), ethologically (by behavior), and toponomically, that is, according to their relationship to the surrounding sedimentary layers. Except in the rare cases where the original maker of a trace fossil can be identified 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 ...
Paleodictyon is a trace fossil, usually interpreted to be a burrow, which appears in the geologic marine record beginning in the Precambrian /Early Cambrian [ 1] and in modern ocean environments. [ 2][ 3][ 4] Paleodictyon were first described by Giuseppe Meneghini in 1850. [ 1] The origin of the trace fossil is enigmatic and numerous candidates ...
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. 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 ...
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. It was produced globally by a variety of organisms, mostly in shallow marine environments, and appears as linear features in sedimentary rocks.
Dinosaur trace fossils. Trace fossils, also called ichnofossils, are structures preserved in sedimentary rocks that record biological activity. Trace fossils made by dinosaurs include such nonbody remains as footprints, eggs, and coprolites (fossil feces), and are important documents of the activities of dinosaurs in life.
A fossil (from Classical Latin fossilis, lit. 'obtained by digging') [ 1] is any preserved remains, impression, or trace of any once-living thing from a past geological age. Examples include bones, shells, exoskeletons, stone imprints of animals or microbes, objects preserved in amber, hair, petrified wood and DNA remnants.
