摘要: A new specimen of Acrochordiceras from the Pelsonian Strzelce Opolskie, Poland, and holotype Silesiacrochordiceras damesi (Noetling, 1880) are described. Ontogenetic changes in shell morphology, based on studies museum specimens Gulf Ismid, Turkey, also presented. The pattern temporal morphologic variability oi acrochordiceratids suggests that they many represent a single lineage, with posslble eexual dimorphism expressed degree involuteness adult specimens. It is proposed to subdivide lineage into five succesive chronospecies genus. Attribution Opolskie A. ippeni Arthaber, 1911 proposed.
