Time the record covers
At most 11 million years on record.
Every occurrence read is dated to somewhere between 72.2 Mya and 61.66 Mya, and nothing in the dating separates them, so that window is what the record shows rather than a span.
83 occurrences of Planomalina yaucoensis 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
83 occurrences- Late Cretaceous77%
- Paleocene23%
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 83 sites for Planomalina yaucoensis, 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.

No 3D scan of Planomalina yaucoensis was found in MorphoSource and Sketchfab.
Smithsonian Open Access was not reached for this taxon, so this list is what the others held rather than everything there is.
This is what the site found, which is not the same as what exists.
