Time the record covers
At least 13 million years on record.
The record covers at least 79.5 Mya to 66 Mya. No occurrence read is dated outside 85.4 Mya to 61.66 Mya.
88 occurrences of Hedbergella holmdelensis 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
88 occurrences- Late Cretaceous67%
- Paleocene33%
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 88 sites for Hedbergella holmdelensis, 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 Hedbergella holmdelensis 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.
