  • according to Hottinger (2006):

CUPULE - radial, rounded ridges on the shell face of conical shells resulting from an arrangement of slightly inflated radial chamberlets alternating in radial position in subsequent cycles.

Remarks: the term "cupule" means "cup" in French and English and refers to the cup-shaped sections perpendicular to an elongate barrel vault forming the radial chamberlets as in Orbitolinopsis, Orbitolinella or Halkyardia.
