| Abstract/Notes | Four species of Emilites are now known; these are E. incertus (Böse), E. plummeri Ruzhencev, E. brownwoodi n. sp., and E. bennisoni n. sp. Representatives of this genus may occur as early as Middle Pennsylvanian in North America to as late as Early Permian in the Soviet Union. All described taxa are from North America except E. plummeri, which is from the Soviet Union. Because Emilites is extremely rare in upper Paleozoic ammonoid assemblages, generic and species level phylogenetic relationships are poorly understood. Emilites is not considered to be a good generic-level zone indicator due to its relatively long time range and its rarity. |
