The trace fossil record is important in determining the timing of the appearance of bilaterian animals. The earliest reasonable fossil evidence for total-group bilaterians comes from undisputed complex trace fossils that are younger than about 560 Ma, and these diversify greatly as the Ediacaran .

In fact, in the studied offshore deposits Trichophycus is commonly the only mid-tier component, in contrast to younger marine deposits that typically display a large variety of mid-tier trace fossils dominated by those produced by crustacean (Carmona et al.
Trace fossils have a further utility as many appear before the organism thought to create them, extending their stratigraphic range. First described as Phycodes pedum (Seilacher, 1955), this ichnospecies has also been assigned to Trichophycus (Geyer & Uchman, 1995) or Treptichnus (Jensen, 1997).

While we are most familiar with relatively spectacular fossil hard part remains such as shells and bones, trace fossils are often less dramatic, but nonetheless very important. Trichophycus Miller and Dyer refers mainly to cylindrical trace fossils with delicate striae (Osgood, 1970), but the formation of a series of upward-curved probes was recognized as the most characteristic feature of this ichnogenus (Geyer and Uchman, 1995).
