Time the record covers

At least 246 million years on record.

The record covers at least 247 Mya to 11.7 ka. No occurrence read is dated outside 250.8 Mya to 0 Mya.

1,374 occurrences of Plicatula on record, most of them in the Late Cretaceous. The Paleobiology Database records this as a living group. 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

1,374 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 1,374 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. 323 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.
