Late Permian nautiloids from Baghuk Mountain (Central Iran)
Abstract
The Wuchiapingian to Changhsingian (Late Permian) Hambast Formation of sections at Baghuk Mountain and Shahreza (Central Iran) has yielded diverse nautiloid assemblages from the early Wuchiapingian Araxoceras beds (nine species), the early Wuchiapingian Prototoceras beds (one species), the late Wuchiapingian Vedioceras beds (twelve species) and the late Changhsingian Paratirolites beds (two species). These species belong to 14 genera, six of which are new: Lutonautilus gen. nov., Epitainoceras gen. nov., Ocunautilus gen. nov. in Ocunautilidae fam. nov., Aifinautilus gen. nov., Baghuknautilus gen. nov. and Shahrezanautilus gen. nov. A total of 24 species are described, all of which are new: Serometacoceras pentagonum sp. nov., Lutonautilus cratus gen. et sp. nov., Lutonautilus elachus gen. et sp. nov., Lutonautilus cymus gen. et sp. nov., Tainoceras hystatum sp. nov., Epitainoceras lutense gen. et sp. nov., Foordiceras eicosacanthum sp. nov., Foordiceras decacanthum sp. nov., Foordiceras ascetum sp. nov., Tardunautilus aperimos sp. nov., Domatoceras myloide sp. nov., Domatoceras canonium sp. nov., Domatoceras ocomphalum sp. nov., Ocunautilus diplodocus gen. et sp. nov., Ocunautilus coelodesmus gen. et sp. nov., Ocunautilus tachytrephus gen. et sp. nov., Aifinautilus icanus gen. et sp. nov., Azarinautilus phorminx sp. nov., Liroceras leptum sp. nov., Paraliroceras macrogaster sp. nov., Permonautilus adelphidus sp. nov., Baghuknautilus aplomorphus gen. et sp. nov., Shahrezanautilus weyeri gen. et sp. nov. and Shahrezanautilus ghaderii gen. et sp. nov. This nautiloid assemblage is remarkable for its high endemism. Although many genera known from the Transcaucasian region are represented, there is no correspondence at the species level.
