Time the record covers
At least 41 million years on record.
The record covers at least 41.03 Mya to 11.7 ka. No occurrence read is dated outside 48.07 Mya to 0 Mya.
641 occurrences of Coscinodiscus marginatus on record, most of them in the Pleistocene. 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
641 occurrences- Eoceneunder 1%
- Miocene23%
- Pliocene22%
- Pleistocene52%
- Holocene4%
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 641 sites for Coscinodiscus marginatus, 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.

No 3D scan of Coscinodiscus marginatus was found in Sketchfab.
Smithsonian Open Access and MorphoSource were 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.
