Ichnology is the study of trace fossils of once-living things.^[1]

Burrows, trackways, trails and borings are all examples of traces made by organisms.^[1] Scientists study traces made by plants and animals to try to determine their behavior.^[2] An ichnologist is a scientist whose area of study and research is ichnology.

A species name given to a fossil is called an ichnospecies. It is written in italics with a lower case initial. It is shown to be an ichnospecies by the abbreviation "isp".^[3]
