Costellariidae
Costellariidae sometimes called the "ribbed miters" is a taxonomic family of minute to medium-sized predatory sea snails, marine gastropod mollusks. This family of snails is also sometimes referred to as Vexillum miters. The main family of miter shells however is Mitridae, a closely related group.

Time the record covers
At least 93 million years on record.
The record covers at least 93.9 Mya to 11.7 ka. No occurrence read is dated outside 100.5 Mya to 0 Mya.
887 occurrences of Costellariidae 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
887 occurrences- Late Cretaceousunder 1%
- Paleocene13%
- Eocene29%
- Oligocene13%
- Miocene26%
- Pliocene10%
- Pleistocene8%
- Holoceneunder 1%
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 379 sites for Costellariidae, and this reads 240 of them. Of that, one read hit the database's own return limit, so every count below is a floor rather than a total. 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 887 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. 144 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. Relayed as the Paleobiology Database holds them, not checked against what they resolve to.
