(Riedel and Sanfilippo, 1970)
The top of the zone is defined by the morphotypic first appearance of Podocyrtis goetheana and is coincident with the lower limit of the Podocyrtis goetheana Zone.
Event included in the zone is:
- Tm Podocyrtis trachodes
- The lower limit of the zone is approximately synchronous with Tm Phormocyrtis striata striata; Bm Tristylospyris triceros
The base of the zone is defined by the evolutionary transition from Podocyrtis mitra to Podocyrtis chalara and is coincident with the upper limit of the Podocyrtis mitra Zone.
