Alveolinidae
Alveolinidae is a family of spheroidal to fusiform milioline foraminifera with multiple apertures and complex interiors in which chambers are subdivided into chamberlets and subfloors interconnected by passageways. As with all Miliolina, the test wall in alveolinids is porcellaneous and imperforate. In living individuals the pseudopodia emerge through the multiple apertures that line the apertural or leading face of the test.

Time the record covers
At least 119 million years on record.
The record covers at least 119.57 Mya to 129 ka. No occurrence read is dated outside 121.4 Mya to 11.7 ka.
513 occurrences of Alveolinidae on record, most of them in the Eocene. 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
513 occurrences- Early Cretaceousunder 1%
- Late Cretaceous7%
- Paleocene19%
- Eocene40%
- Oligocene12%
- Miocene13%
- Pliocene6%
- Pleistocene4%
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.

The Paleobiology Database records 286 sites for Alveolinidae, and this reads 240 of them. The number is how many of those sites it was catalogued from too. The 24 sharing the most are listed.
This is not a list of everything alive at the time. It is only what has come out of the same ground as this animal and been written down.

Each of the 513 occurrences read was entered from one of these publications, ordered by how many each accounts for. This is not a search for papers mentioning the name. 93 further references are not listed. Entries link to doi.org where the Paleobiology Database holds an identifier, and to its own record where it does not.
