Euomphaloidea

Euomphaloidea, originally Euomphalacea, is an extinct superfamily of marine molluscs that lived from the Early Ordovician to the Late Cretaceous, included in the Gastropoda but speculated as instead perhaps Monoplacophora.

Time the record covers

At least 435 million years on record.

The record covers at least 483.4 Mya to 48.07 Mya. No occurrence read is dated outside 486.85 Mya to 37.71 Mya.

3,453 occurrences of Euomphaloidea on record, most of them in the Ordovician. 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

3,453 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 3,453 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. 669 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.
