Treptichnus is a genus of trace fossils (with modern analogues) representing a three-dimensional burrow. These fossil traces are known from marine, brackish, and freshwater deposits from the Ediacaran (550 million years ago) to the Upper Oligocene (24 mya).
Treptichnus represents the oldest known example of a complex, three-dimensional burrow. One of its ichnospecies, Treptichnus pedum, is of major paleontological importance as it defines the global boundary between the Ediacaran and Cambrian periods (539 mya).
