Species Praehedbergella gaultina Morozova 1948

Discussion / Comments:

Moullade et al. (2002):
Our recent observations concerning material from Site 1049 of Leg ODP 171B show that early– middle Albian sub-homeomorphs of Hedbergella planispira, which are very similar to the typical late Albian–Cenomanian form of Tappan (1940) in many morphological aspects, differ from it in being smaller and, especially, in having a microperforate, instead of macroperforate, test.
