Genus Actinoporella (Gümbel)

Actinoporella gr. podolica (Alth)

( Fig. 4 l-n; Fig. 5i )

We use “gr.” to indicate that in our opinion we are not dealing with a single species but possibly with several (Granier, 1995). These forms were identified in both Upper Hauterivian Urgonian units as well as in the Middle Berriasian Pierre Châtel Formation.
