1,718 occurrences of Pholadomya 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

1,718 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.

2,217 taxa

The Paleobiology Database records 1,209 sites for Pholadomya, and this reads 240 of them. Of that, one read hit the database's own return limit, so every count below is a floor rather than a total. 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.

382 references

Each of the 1,718 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. 370 further references are not listed. Each entry links to the Paleobiology Database's own record for the work.
