Species Morozovella acuta Toulmin 1941


Discussion / Comments:
Toumarkine & Luterbacher (1985):
The conicotruncate test of this species has a well developed 'keel' and ornamented umbilical shoulders at least in the early chambers of the last whorl. The last chamber occupies up to one-third of the whorl.
Pearson et al. (2006):
