Scaphitidae
Scaphitidae is a family of extinct cephalopods belonging to the family of heteromorph ammonites. There is a possible fossil record of them being the last ammonites with fossils dating to the Danian of the Paleocene in Denmark, the Netherlands, the US and Turkmenistan.

Time the record covers
At least 40 million years on record.
The record covers at least 106.3 Mya to 66 Mya. No occurrence read is dated outside 143.1 Mya to 61.66 Mya.
1,460 occurrences of Scaphitidae 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
1,460 occurrences- Early Cretaceous3%
- Late Cretaceous96%
- Paleoceneunder 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 1,059 sites for Scaphitidae, 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 1,460 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. 192 further references are not listed. 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.
