assemblage zone
assemblage zone (coenozone, faunizone) Biostratigraphic unit or level of strata characterized by a particular assemblage of animals or plants. An assemblage zone is named after one or more of the distinguishing fossils present, which are chosen without regard for their total time ranges, so that the assemblage is of purely environmental significance. Compare CONCURRENT RANGE ZONE.
