[[Trace fossil]]s are [[Biological classification|classified]] in various ways for different purposes. Traces can be classified [[#Taxonomic classification|taxonomically]] (by morphology), [[#Ethologic classification|ethologically]] (by behavior), and [[#Toponomic classification|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 confidence, phylogenetic classification of trace fossils is an unreasonable proposition.
