Time the record covers
At least 68 million years on record.
The record covers at least 141 Mya to 72.2 Mya. No occurrence read is dated outside 145.06 Mya to 66 Mya.
2,098 occurrences of Desmoceratidae on record, most of them in the Early 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
2,098 occurrences- Late Jurassicunder 1%
- Early Cretaceous64%
- Late Cretaceous36%
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 named rock units Desmoceratidae has been recovered from, largest first. Drawn where the rock is now, not where it formed. 194 further formations hold fewer occurrences each and are not listed. 727 occurrences have no formation on record, which is common for older literature.

The Paleobiology Database records at least 1,419 sites for Desmoceratidae, 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 2,098 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. 328 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.

No 3D scan of Desmoceratidae 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.
