Alveolinella

Alveolinella is a genus of larger fusiform porcelaneous alveolinids from the Miocene to Recent with apertures on the septal face in multiple rows and aligned partitions (septula) dividing the primary chambers. Aveolinella is a larger foraminifer from the milioline family Alveolinidae. Like other miliolines, they have imperforate porcelaneous walls.

10 occurrences of Alveolinella on record, most of them in the Miocene. The Paleobiology Database records this as a living group. Bar height is expected occurrences, not a count: each fossil is spread across the span it is dated to, so a tall narrow bar means tight dating and a low wide one means loose.

When

10 occurrences

These are dates about fossils, not the animal: the record can only begin after it arose and end before it died out, so either end may reach further. Shares are expected occurrences: a fossil dated to a span is counted partly in each period it straddles. More on what this infers.
