Pholadomya
Searched as Pholadomya (Bucardiomya) aubryi. The Paleobiology Database treats Pholadomya as the accepted name.
Pholadomya is a genus of saltwater clams, marine bivalve molluscs in the family Pholadomyidae.

Time the record covers
At least 6.7 million years on record.
The record covers at least 161.5 Mya to 154.8 Mya. No occurrence read is dated outside 165.3 Mya to 149.2 Mya.
5 occurrences of Pholadomya on record, most of them in the Late 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
5 occurrencesThese 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 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.
