Time the record covers
At least 477 million years on record.
The record covers at least 477.1 Mya to 11.7 ka. No occurrence read is dated outside 486.4 Mya to 0 Mya.
8,486 occurrences of Nuculanoidea on record, most of them in the Eocene. 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.

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 Nuculanoidea has been recovered from, largest first. Drawn where the rock is now, not where it formed. 1,157 further formations hold fewer occurrences each and are not listed. 1,218 occurrences have no formation on record, which is common for older literature.

The Paleobiology Database records at least 1,309 sites for Nuculanoidea, 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.
