Time the record covers

At least 37 million years on record.

The record covers at least 110.1 Mya to 72.2 Mya. No occurrence read is dated outside 113.2 Mya to 66 Mya.

389 occurrences of Placenticeratidae 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

389 occurrences

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.

Each of the 389 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. 113 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.
