Entoliidae

The Entoliidae, also referred to as the entoliids, are a taxonomic family of saltwater clams, marine bivalve mollusks in the order Pectinida. They are related to and are considered the ancestors of modern scallops. In the geological record the family contains at least seven species in five different genera, though only one is extant and it is very rare and cryptic, inhabiting the Caribbean and central west Pacific Ocean in small, disjointed populations.

At least 353 million years on record.

The record covers at least 358.86 Mya to 5.333 Mya. No occurrence read is dated outside 365.2 Mya to 2.58 Mya.

2,191 occurrences of Entoliidae on record, most of them in the Early Jurassic. The Paleobiology Database records this as a living group, and the chart stops with its fossils rather than at the present. 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

2,191 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.
