Nuculida

Nuculida is an order of small saltwater clams, marine bivalve mollusks, within the subclass Protobranchia. "Nuculida" is sometimes spelled "Nuculoida". This order contains a single superfamily, Nuculoidea, which encompasses two families, the extant Nuculidae and the extinct Praenuculidae. Clams in the family Nuculidae are commonly known as nut clams.

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 486.85 Mya to 0 Mya.

5,037 occurrences of Nuculida 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

5,037 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 5,037 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. 1,016 further references are not listed.
