Sporadoceras terminusDzik, 2006 from the P. jugosus Zone at Dzikowiec  and Kowala in the Holy Cross Mountains.

 

Diagnoza

Suture with bulbous lobes and saddles, additional ventral and flank lobes of subequal depth; rather globose conch.

Porównanie

Sporadoceras orbiculare (Münster, 1832) as interpreted by Korn (1999; Korn and Klug 2002) may represent a connecting link between S. nux and S. terminus sp. n., being intermedioate in its geological age and in the inferred conch globosity at comparable stages of the ontogeny.
