چکیده

مرز فرازنین ـ فامنین در برش کال سردر (شرق طبس، ایران مرکزی) بر اساس زیای کنودونتی مورد بررسی قرار گرفته است. شناسایی 33 گونه و زیرگونه این مکان را فراهم ساخت تا براساس پرکندگی آنها در ستون چینه شناسی، یک بخش بدون سنگواره و پنج زیست زون تشخیص داده شود که به ترتیب شامل Upper rhenana، upper part of Upper rhenana – linguiformis، Lower to Middle triangularis، Upper triangularis و Lower crepida می باشند. تجزیه و تحلیل رخساره زیستی کنودونتها نشانگر روند عمیق شدن در طول فرازنین پسین می باشد که با یک اُفت شدید سطح آب دریا در ابتدای فامنین پیشین دنبال می شود. کمی بعد و دوباره در طول فامنین، محیط عمیقتر بر منطقه حاکم می گردد. در این پژوهش محدوده سنی جدیدی برای گونه ی P. planarius پیشنهاد می شود که برابر زیست زونهای Lower hassi – linguiformis می باشد.
