Jan 1, 2007 · The trace fossil Zoophycos can be considered a good example of a taxonomic problem, resulting from old interpretations and lack of studies on the type material. Zoophycos is a complex and enigmatic ichnofossil that has challenged generations of geologists and ichnologists for over a century. Fossils are often said to take a million years to form.
