Hercoglossidae
Hercoglossidae is a family of nautilid cephalopods in the superfamily Nautilaceae. It was established by Spath in 1927 for smooth, involute nautiloids characterized by a suture with differentiated elements, known from the Upper Jurassic to the Oligocene.

Time the record covers
At least 73 million years on record.
The record covers at least 100.5 Mya to 27.3 Mya. No occurrence read is dated outside 106.3 Mya to 23.04 Mya.
343 occurrences of Hercoglossidae on record, most of them in the Paleocene. 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
343 occurrences- Early Cretaceousunder 1%
- Late Cretaceous7%
- Paleocene48%
- Eocene44%
- Oligoceneunder 1%
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 289 sites for Hercoglossidae, 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.

Each of the 343 occurrences read was entered from one of these publications, ordered by how many each accounts for.
