Ichnofacies An ichnofacies is an assemblage of trace fossils that provide an indication of the conditions that their formative organisms inhabited. ==Concept== Trace fossil assemblages are far from random; the range of fossils recorded in association is constrained by the environment in which the trace-making organisms dwelt.〔 Palaeontologist Adolf Seilacher pioneered the concept of ichnofacies, whereby the state of a sedimentary system at its time of deposition could be deduced by noting the fossils in association with one another.
