Orbitolina
Searched as Orbitolina conica. The Paleobiology Database treats Orbitolina as the accepted name.
Orbitolina is an extinct genus of foraminifera belonging to the order Textulariida and family Orbitolinidae. Fossils of this genus are widely found in beds deposited in the Tethys Ocean ranging from Aptian to Cenomanian in age. It has been used as a shallow carbonate platform facies marker and as a Cretaceous index fossil.

Time the record covers
At most 78 million years on record.
Every occurrence read is dated to somewhere between 143.1 Mya and 66 Mya, and nothing in the dating separates them, so that window is what the record shows rather than a span.
16 occurrences of Orbitolina on record, most of them in the Late Cretaceous. 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
16 occurrencesThese 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 64 sites for Orbitolina, and this reads all 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 16 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. 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.
