ichnotaxon

Etymology
.

Noun

 * 1)  A grouping, analogous to a biological taxon, used to classify footprints, burrows or other trace fossils, and hence, indirectly, the organisms that might have produced them.

Usage notes

 * Classification generally extends only to the specification of ichnogenus and ichnospecies. Some researchers use higher-level categories, even as far as ichnosuperclass, but their usefulness is disputed.
 * Following the convention of ordinary taxonomy, both ichnogenus and ichnospecies are rendered in italics; the combination is called a.
