Dinosaur Tracks and Ichnology

This web site provides links to sites on dinosaur tracks and other aspects of ichnology--the study of trace fossils. Trace fossils are any marks or other evidence of an ancient animal made while it was still alive, rather than its dead remains. Trace fossils include ancient footprints, bite marks, claw marks, burrows, borings, dens, nests, hives, coprolites, invertebrate trails, feeding traces, and any other marks indicating the movement, activity, or behavior of an ancient creature. Sometimes it may be difficult to determine if a marking is a trace fossil or a body fossil. For example, a skin impression can be either, depending on whether it was made while the animal was alive, or after death. Some fossils can be both body and trace fossils. For example, a fossil egg containing an embryo (a rare find!) can be considered a track fossil of an adult but a body fossil of the juvenile.
