Abstrakt: A Late Serpukhovian ammonoid assemblage was recovered from the Mid-Carboniferous boundary beds cropping out in an active stone crushing quarry on the right bank of the Iset River (Middle Urals). The ammonoid assemblage includes Epicanites sp., Stenopronorites uralensis (Karpinsky), Delepinoceras bressoni Ruzhencev, Proshumardites principalis Ruzhencev et Bogoslovskaya, Deleshumardites delepinei (Schindewolf), Stenoglaphyrites isetensis sp. nov., Glaphyrites sp., Fayettevillea sp., Syngastrioceras sp., Eumorphoceras aff. transuralense Ruzhencev et Bogoslovskaya, characterizing the Deleshumardites-Delepinoceras (=Fayettevillea-Delepinoceras) Genozone, which correlates with the E2 zone of Europe and its equivalents throughout the world. The assemblage is described and compared with ammonoid associations of this age from other regions of the world. A new species, Stenoglaphyrites isetensis Nikolaeva sp. nov., is described.
