Information about Ichnology
Ichnology is the branch of paleontology that deals with traces of organismal behavior. The division of ichnology dealing with trace fossils is paleoichnology, while neoichnology is the study of modern traces. Parallels can often be drawn between modern traces and trace fossils, helping scientists to decode the possible behavior and anatomy of the trace-making organisms even if no body fossils can be found. An ichnologist is a scientist whose area of study and research is ichnology.
Ichnologic studies are based on the discovery and analysis of biogenic structures: features caused by a living organism. Thus, burrows, trackways, trails and borings are all examples of biogenic structures, but not casts or molds of dead shells or other bodily remains. To keep body and trace fossils nomenclatorially separate, ichnospecies are erected for trace fossils. Ichnotaxa are classified somewhat differently in zoological nomenclature than taxa based on body fossils (see trace fossil classification for more information).

Examples
- Late Cambrian trace fossils from intertidal settings include Protichnites and Climactichnites, amongst others.
- Mesozoic dinosaur footprints including ichnogenera such as Grallator, Atreipus and Anomoepus.

trackway is a set of impressions in the soft earth, usually a set of footprints, left by a life-form. A fossil trackway is the fossilized imprint of a trackway. Trackways have been found all over the world.

An ichnotaxon (plural ichnotaxa) is defined by the International Code of Zoological Nomenclature as "a taxon based on the fossilized work of an organism". Ichnotaxa are names used to identify and distinguish morphologically distinctive trace fossils.

The International Code of Zoological Nomenclature is a set of rules in zoology that have one fundamental aim: to provide the maximum universality and continuity in the naming of all animals according to taxonomic judgment.

Trace fossil classification parallels the taxonomic classification of organisms. In trace fossil nomenclature a Latin binominal name is used, just as in animal and plant taxonomy, with a genus and specific epithet.

The Cambrian is a major division of the geologic timescale that begins about 542 ± 1.0 Ma (million years ago) at the end of the Proterozoic eon and ended about 488.3 ± 1.7 Ma with the beginning of the Ordovician period (ICS, 2004).

Protichnites is a genus of trace fossil consisting of the imprints made by the walking activity of an unknown arthropod. It includes two rows of tracks and a linear depression between the two rows. This depression is thought to be the result of a dragging tail.

Climactichnites is a genus of trace fossil formed on sandy tidal flats in the Saint Lawrence Seaway portions of Canada and northern United States, and in Missouri, around 510 Ma during late Cambrian time.

The Mesozoic Era is one of three geologic eras of the Phanerozoic eon. The division of time into eras dates back to Giovanni Arduino, in the 18th century, although his original name for the era now called the 'Mesozoic' was 'Secondary' (making the modern era the 'Tertiary').

Grallator is an ichnogenus representative of a bipedal theropod dinosaur which roamed the supercontinent Pangea in the Late Triassic and the Early Jurassic.[1] The trackmaker likely resembled Coelophysis.

Anomoepus gracillimus is the name assigned to footprints in the Late Triassic beds of the Connecticut River Valley, Massachusetts, USA in 1802. All four feet have left impressions. The smaller forefeet have five toes, whereas the larger hind feet have three toes.
