Description: Completely spherical, pore-like apertures ('megapores') beginning to move away from the sutures of the embryonic chambers and become areal (Lillburnian onwards).
Distribution: Lillburnian.
Comment: First evolutionary appearance marks the base of the Lillburnian in the stratotype at Clifden. The transition to typical O. universa takes place in the Lillburnian but morphotypes of O. suturalis (mostly immature O. universa) are still found higher in the Miocene, particularly in neritic facies.
