Selliporella neocomiensis (Radoičić)

( Fig. 3f )

This species, also known as Diplopora johnsoni Praturlon , is commonly referred to the Tithonian-Berriasian interval. Younger occurrences (Hauterivian) are probably erroneous dating ( Granier & Deloffre, 1993; Bucur & Săsăran, 2003). The unique specimen was found in the transition between the Vions and Pierre Châtel formations.

The organogenus Carpathoporella Dragastan, 1995 , possibly refers to skeletal remains very similar to isolated calcified laterals of Selliporellas; these bioclasts might be broken pieces of a discrete species. According to Schlagintweit and Gawlick (2009), this form refers to octocorallian debris, a view that we do not share. We identify Carpathoporellas in both Urgonian units
