trace fossils must reflect original biological behavior of the organism. Major Concepts in the Study of Traces. 1. One organism can produce multiples traces. 2. Different organisms produce similar traces. (i.e. an ichnotaxon. ≠ a biological species) 3. It is usually impossible to know what organism (s) produced a particular trace fossil.
