Pholadomya (Bucardiomya)
Not Pholadomya (Bucardiomya). This is Cardium protei (Brongniart, 1821), a relative — both are Pholadomyidae.

Time the record covers
At least 188 million years on record.
The record covers at least 211.18 Mya to 23.04 Mya. No occurrence read is dated outside 227.3 Mya to 5.333 Mya.
202 occurrences of Pholadomya (Bucardiomya) on record, most of them in the Middle Jurassic. 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
202 occurrences- Late Triassic1%
- Early Jurassic10%
- Middle Jurassic47%
- Late Jurassic23%
- Early Cretaceous4%
- Late Cretaceous4%
- Paleocene2%
- Eocene6%
- Miocene1%
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.

The named rock units Pholadomya (Bucardiomya) has been recovered from, largest first. Drawn where the rock is now, not where it formed. 27 further formations hold fewer occurrences each and are not listed. 59 occurrences have no formation on record, which is common for older literature.

The Paleobiology Database records 141 sites for Pholadomya (Bucardiomya), and this reads all of them. 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.

Each of the 202 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. 42 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.

No 3D scan of Pholadomya (Bucardiomya) was found in MorphoSource and Sketchfab.
Smithsonian Open Access was not reached for this taxon, so this list is what the others held rather than everything there is.
This is what the site found, which is not the same as what exists.
