Oliva
Searched as Oliva mississippiensis santander. The Paleobiology Database treats Oliva as the accepted name.
Oliva is a genus of medium-sized to large sea snails, marine gastropod mollusks in the subfamily Olivinae of the family Olividae, the olive snails or olive shells. Many former species of Oliva have been reclassified under genus Americoliva.

Time the record covers
At most 6.6 million years on record.
Every occurrence read is dated to somewhere between 33.9 Mya and 27.3 Mya, and nothing in the dating separates them, so that window is what the record shows rather than a span.
6 occurrences of Oliva on record, most of them in the Oligocene. The Paleobiology Database records this as a living group, and the chart stops with its fossils rather than at the present. 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
6 occurrences- Oligocene100%
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 407 sites for Oliva, 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.
